The Sky Scout is a radio control model plane designed for users over age 14. For those under age 14, please seek the help of your parents, guardian or the help of a skilled RC pilot. Improper assembly or user negligence can lead to serious injury and/or property damage to yourself or other persons. Hitec is not responsible for any damages or injuries caused by the user’s negligence or improper assembly of the

model. Be sure to read the instruction manual thoroughly before assembly and ying.

RC functions: rudder, elevator and throttle; optional ailerons

The Sky Scout is manufactured of ELAPOR, a material highly suited for model airplanes. ELAPOR is light, durable and unlike traditional foams it can be bonded successfully with traditional cyanoacrylate adhesives and activators. Do not use foam-safe or “odorless” CA, epoxy or other household glues. It is recommended that you wear safety goggles when using CA glue and be sure to follow the manufacturer’s safety instructions for its use.

Section Two: Assembly Instructions

2. Prepare Snake Sleeves

Cut Parts #52 & #53 to lengths as shown using a razor knife.

3. Reinforcing the motor pod

Glue the 31 mm length of snake outer sleeve inside the motor pod using CA glue.

4. Installing the tailplane lock

Glue the tailplane clip 44, the upper tailplane sleeve 45 and the tailplane frame 46 in the right-hand fuselage shell 4: lightly spray activator thinly

on the plastic parts, and allow a few seconds for the uid to air-dry.

Take care not to glue together the two plastic parts

(tailplane clip 44 and upper tailplane sleeve 45)!

5. Inserting the tailplane slider

Allow the glue to set hard, then insert the tailplane slider 48 to ensure that the parts are accurately aligned.

This part must not be glued in place!

6. Reinforcing the bottom of the fuselage

Cut the outer snake sleeve to a length of 635 mm, then glue it in the channel in the bottom of the right-hand fuselage shell 4. Temporarily t the tailplane slider 48 to position this part accurately, but take care not to glue the parts together.

Fly high with Hitec

Section Two: Assembly Instructions

7. Reinforcing the fuselage nose

Cut the sleeves to a length of 247 mm, and glue them in the upper part ofthe two fuselage shells 3 + 4. Cut the sleeve to a length of 290 mm and glue it in the underside of the right-hand fuselage shell 4.

8. Preparing the cable holders (optional: required for ailerons)

Glue the female plug end of a 12” (30mm) servo extension lead to the

cable holder 29, ush with the edge. Push the cable under the lug on the underside.

9. Installing the cable holders

First spray activator on the joint surfaces of the cable holders 29. Allow

the uid to air-dry, then glue the parts in the appropriate recesses in both

fuselage shells.

10. Gluing the latch catches in place

Glue the latch catches 27 in both fuselage shells. Once again, spray activator onto the plastic part, and allow it to air-dry.

11. Installing the servo mounts

Glue both servo frames 43 in the appropriate openings using CA Glue.

Ensure that no glue gets onto the mount lugs, as this could prevent them holding the servos securely.

Fly high with Hitec

Section Two: Assembly Instructions

12. Preparing the servos for installation

Before installing the servos, set all of them to neutral (center) from the

transmitter: this is accomplished by connecting the servo to a receiver, switching the system on, and centring the stick at the transmitter; check that the transmitter trims are also at the neutral position. Locate the “double-ended” servo output levers with three holes per side,

t them on the servo output shafts at right-angles to the long side of the servo cases. If you nd that the output arm is not accurately at right-angles to the case when the servo is at neutral, rotate the lever through 180°

and try again; the output shaft features an odd number of splines, and reversing the output device will get you “closer to the target”. Install the elevator and rudder servos as a mirror-image pair. You will do the same with the aileron servos, if you choose to install them.

Avoid moving the servo output levers by hand, as this

can easily ruin the gears!

15. Installing the snakes

Slip the pre-formed steel pushrods 51 for the elevator and rudder into the inner tubes 52 (550 mm), and t these into the prepared outer sleeves 53, which are 523 mm long. Connect the pre-formed end of the pushrod to the second hole from the

outside of the servo output arm. Glue the snake outers in the appropriate

channels, running CA glue right along the channel.

16. Preparing the control surface horns

Fit the allen-head grubscrews 24 in the swivel barrels 23: two for elevator

and rudder, four if working ailerons are to be tted. Engage the prepared

swivel barrels in the “Twin” horns 22.

13. Installing the servos in the fuselage

Fit the servos in the servo mounts 43, with the output arms facing down, and the output shafts towards the nose. Trim the unused output arm if needed to prevent interference with the fuselage.

14. Joining the fuselage shells

Spray the joint surfaces of one fuselage shell with activator, apply medium-viscosity CA glue to the joint surfaces of the other shell, then quickly join the two shells, making sure to align the parts accurately.

17. Attaching the horns to the rudder and elevator

Spray activator on the joint surface (the underside) of the horns. Apply CA Glue to the horn recesses in the elevator 6 and rudder. Leave the uid to air-dry for a few seconds, then press the horns into their

recesses. Slip the steel pushrod for the rudder linkage through the hole in the swivel barrel 23. Check once more that the servos are at center before tightening the allen-head grubscrews 24.

We recommend that you apply a drop of medium-strength thread-lock uid

to each grubscrew to prevent them working loose over time.

Fly high with Hitec

Section Two: Assembly Instructions

18. Installing the tailplane frame

To guarantee a secure seating, the tailplane frame 47 must be glued in the recess of the tailplane 6.

21. Releasing the control surfaces

Use a sharp razor knife to remove the foam at the lateral ends of the control surfaces, cutting along the moulded-in end channels only. Repeatedly move the control surfaces to and fro in order to loosen the integral hinges and render them freemoving. Do not separate the control surfaces!

19. Attaching the tailplane

First withdraw the tailplane slider 48 slightly, then insert the tailplane 6 and push the slider back in as far as it will go to secure the tailplane.

Do not glue it! The tailplane should be left detachable for safe, convenient

transport. To remove the tailplane, press the tailplane clips 44 together with two ngers, and at the same time pull the tailplane slider 48 down; the tailplane can now be removed.

20. Connecting the elevator

Slip the inner pushrod for the elevator through the hole in the swivel barrel 23, and check the servo neutral position once more before tightening the allen-head grubscrew 24. We recommend that you apply a drop of medium-strength thread-lock

uid to the grubscrew to prevent it working loose over time.

22. Attaching the servo well covers

Press the left and right servo well covers 11 and 12 into the openings in both sides of the fuselage. They should not be glued in place, as you may have to replace the servos at some time.

23. Installing the wing joiner channel cover

Carefully glue the wing joiner channel covers 9 and 10 in the wing panels 7 and 8.

Take particular care to avoid glue running onto the surfaces which will later make contact with the wing joiner 50. Check that the wing joiner 50 is a snug t in the wings, but only when

you are absolutely condent that there is no active adhesive inside the channel. If you neglect this, youcould nd that the model is glued together

permanently.

Fly high with Hitec

Section Two: Assembly Instructions

24. Attaching the (optional) aileron horns

Assemble the “Twin” horns 22, and glue them in the recesses in both ailerons (wing panels 7 + 8) using CA Glue and activator, as described

earlier.

25. Preparing the aileron servos

See “10. Preparing the servos”.

26. Installing the aileron servos

Wrap adhesive tape round the servos to prevent glue running inside the case. Fit the pre-formed aileron pushrods 26 through the second hole from the outside of the servo output arms. Press the servos and leads into the recesses and channels, and thread the plain end of the pre-formed aileron pushrods 26 through the swivel barrels mounted on the aileron horns. Check once more that the servos are at center before tightening the grubscrews 24 in the swivel barrels.

We recommend applying a drop of medium-strength thread-lock uid to

the grubscrews to prevent them working loose.

28. Installing the cable sleeves

To avoid kinking the aileron servo leads, glue 18 mm lengths of snake

outer sleeve (3.2mm OD) in the recess where the cables exit the wing.

29. Installing the rewall

Glue the rewall 40 in place using thick CA glue. Don’t use activator for this joint, as you will need a certain amount of time to position and align

the rewall correctly.

27. Servo lead length, aileron connections

Draw the servo leads out of the wings 7 + 8 where the wing meets the

fuselage.

30. Gluing the cowl screw support in place

Glue the cowl screw support 42 at the front end of the motor pod.

Fly high with Hitec

Section Two: Assembly Instructions

31. Installing the motor

Fix the motor in place using two M3 x 6 screws. Apply a drop of medium-

strength thread-lock uid to the screws.

Slip the tapered collet through the driver 58 and place this assembly in the propeller boss 55. The washer 59 and the shakeproof washer 64 are

tted from the other side.

Screw the M6 nut 63 on the taper collet 58. Fit the taper collet 58 on the

motor shaft and tighten the nut rmly before tting the spinner.

32. Installing the motor cowl

Fit the three screws 30 to secure the motor cowl 41.

33. Assembling the propeller

Attach the propeller blades 57 to the propeller boss 55 using the two dowel pins 62.

Fit the O-ring 61 through the spinner cone 56.

Fold the propeller blades 57 back, and pass them through the ends of the O-ring 61 which project from the sides of the spinner. Take care to avoid the sharp edges of the propeller blades causing damage to the O-ring 61. Fix the spinner to the propeller boss 55 using the two pan-head self-tapping screws 60.

Fly high with Hitec

Section Two: Assembly Instructions

34. Completing the canopy

Glue the latch tongues 28 in the recesses in the canopy 5. Use thick CA glue initially, and t the canopy on the model immediately,

so that the latch components align themselves automatically. Wait for at least two minutes before removing the canopy, then apply drops of thin CA

glue to the gaps in the latches to glue them in place, ush with the foam.

36. Installing the ight battery and receiver

Deploy the receiver aerial(s) as described in the RC system instructions.

The aerial tube installed in the underside of the fuselage is intended for

conventional MHz systems. If you are using a 2.4GHz system, cut slits in the foam material (e.g. in the area of the canopy ange) and press the

short aerials into them.

NOTE: When positioning these components you should bear in mind the recommended Center of Gravity (CG) at point 40. Stick the strips of Velcro tape 20 and 21 (loop side) to the inside of the fuselage oor. Note

that the adhesive on the tape is not adequate for this application, so x

the tape with CA glue for additional security.

The nal position of the ight battery is determined when you check the model’s balance point (Center of Gravity - CG). Check to make sure that the Velcro tape for the ight battery is rmly secured. If you neglect this, your battery could come loose in ight. Always check that the ight

pack is secure before every ight!

Connect the servo leads to the receiver. Switch the transmitter on, then

connect the ight battery in the model to the speed controller, and the

controller to the receiver. This model requires a BEC-type speed controller

(receiver power supply from the ight battery).

Now switch the motor on briey, and check once more that the propeller rotates in the correct direction (clockwise looking at the spinner). If it spins

in the reverse direction, switch any two of the three motor wires to correct it.

Always hold the model securely when testing the power system, and remove any loose, lightweight objects before and behind the model before the propeller does it for you.

Do not connect the battery to the speed controller until you have switched the transmitter on, and are certain that the throttle control is at the “OFF” position.

Even small motors and propellers are capable of inicting injury!

35. Installing the wings

Slide the wing joiner 50 into one of the wing panels as shown in the

illustration, then t the joiner through the fuselage. Before the wing makes

contact with the fuselage, connect the aileron servo lead to the extension lead already installed in the fuselage.

Connect the plug and socket, then push the wing fully into place; the cable will now form itself into a loop in the space designed for it.

Fit the other wing panel onto the joiner, and connect the aileron servo lead to the extension lead already installed in the fuselage, as described previously.

37. Finishing the model

The kit includes a multi-color decal sheet (A + B) for adding the nal

touches to the model. Cut out the individual decals and apply them to the airplane in the arrangement shown on the box illustration. The canopy can be colored black using a waterproof felt-tip pen. If you wish to apply an all-over color scheme, you can use most common spray enamel paints available at your local hardware store. You must use caution and not over apply the paint instead spraying several light coats. For tips on painting our models please refer to the FAQ section on our website.

Section Three: Preparing Your Model for Flight

1. Check Transmitter Inputs

Before attempting ight ensure that your controls are set up properly and give the appropriate response to your transmitter inputs. A complete set up

guide appears at the end of this manual in Appendix B: Transmitter Control Surface Movements. If you have any questions about this consult with a

local experienced ier or your local RC Hobby Retailer or contact Hitec Customer Support.

2. Setting the control surface travels

It is important to set the correct control surface travels, otherwise your model will not respond to your control commands smoothly and evenly. To do this you need to complete all the electrical connections as described in the RC system instructions. NOTE: when we refer to a model aircraft, the terms “right” and “left” always apply to the model when viewed from above, with the nose pointing away from the you.

ELEVATOR: Up-elevator (stick back, towards you) should be about 5 mm; down elevator (stick forward, away from you) approx. 4 mm. RUDDER: The rudder should move 10 mm to either side of center, as measured from the widest part of the control surface. AILERONS: The ailerons should deect 8 mm up and 4 mm down. When you move the aileron stick to the right, the aileron on the right-hand wing

should deect up; that on the left-hand wing down. If your radio control system does not include the required mixing to set up differential aileron travel (as described above), the model will still y well with symmetrical (non-differential) travels. If you are a beginner, you will probably notice no difference in any case. However, accurate rolling maneuvers are more difcult to y with symmetrical aileron travels.

NOTE: If you cannot set the recommended travels using your transmitter’s adjustment facilities, you will have to re-position the pushrod connections, using different holes at the servo or horn.

3. Balancing the model

Like every aircraft, your Sky Scout must be balanced correctly if it is to y well and stably. To check the Center of Gravity (CG) you must rst assemble your model completely as if you were ready to y, and install the ight battery.

The correct CG is marked at a point about 5 mm from the rear edge of the wing joiner cover, and the model must balance at this point. This setting corresponds to about 78 mm aft of the wing root leading edge, measured either side of the fuselage.

Support the model under both wings on two ngertips at the marked point, and it should balance level. Minor corrections can be made by adjusting the position of the ight battery. Once you have established the correct position for the battery, mark this in

the fuselage to ensure that it is always positioned correctly.

4. Safety

Safety is of the utmost importance when ying any model aircraft. Third party insurance is mandatory. If you join a model club or association, suitable coverage will usually be available through the organization. It is your personal responsibility to ensure that your insurance is adequate (i.e. that its cover includes powered model aircraft). Always y in such a way that you do not endanger yourself or others. Bear in mind that even the best RC systems are subject to outside interference. No matter how many years of accident-free ying you have there is always the possibility of an unforeseen problem or error that can cause an accident

Make it your job to keep your models and your radio control system in perfect operating condition at all times. Check and observe the correct charging procedure for the batteries you are using.

Before every ight, check that the battery, the wings and the tail panels are attached and rmly seated. Check in turn that each control surface is operating correctly!

Where to y – Using Airelds

1) Use an ofcial model aireld if possible when ying your model.

2) Check that other pilots and spectators are positioned safely before ying your model.

3) Wait for other pilots to land their models if they are ying already.

4) Always remember that the pilot is responsible for any outcome that may occur during the ight.

5) Do not y the plane behind yourself or others.

6) Seek help from an experienced pilot for your rst ight.

7) Do not y under the inuence of alcohol or drugs or if you are feeling ill.

8) Be sure to do pre-ight safety checks of the model before ying.

If you have no prior experience with ying a radio controlled model, please take the time to read through the “Appendix A” entitled “The basics of model ying”.

Pre-Flight Inspections and Cautionary Notes

The following is based on common safety precautions for ying RC models. Please read the following information before attempting to y your model. Check all safety aspects of your model before ying for a safe ight.

1. Pre-flight Model Inspection

The following inspection should be done BEFORE plugging in the battery.

a) Check to make sure the models is in safe operating condition and that there is no damage to the wings or the tail. b) Check to ensure the wings and tail plane are properly seated and locked into position c) Make sure the prop and hub are tightly mounted to the motor d) Make sure the propeller spins freely and that the blades open and close properly

2. Pre-flight Radio Check

The following checks are done with the radios system turned on and the model’s main battery plugged in and fully charged. Be sure to turn on the transmitter and check to make sure that the throttle is in the OFF position BEFORE connecting the main battery. If using a conventional XX MHz frequency system, ensure that your chosen channel is free before beginning these tests.

a) Range Check: Follow the instructions provided by your RC system manufacturer. The transmitter battery and ight pack must be fully

charged in accordance with the manufacturer’s recommendations before conducting this test.

b) Function Check: Check to make sure the model responds correctly to the transmitter inputs.

If you are unsure about the proper range, operation or functionality of any part of the radio system, do not y the model! If you cannot identify and solve the problem, send the whole RC system (including battery, switch harness and servos) to your system manufacturer for inspection.

Pre-flight safety checks

The following instructions are for users to easily understand what to check for before the ight how to take-off, land and adjust settings during the ight.

The instruction manual cannot address every situation that may occur, but it does explain common situations that occur which could be useful for you

when ying.

1. Check whether the wings or the tail are damaged.

2. Check if the joints and the propeller are assembled rmly.

3. Connect the main battery AFTER turning on the transmitter. Keep away from other people, and especially away from the propeller.

4. Once the main battery is connected the motor could start suddenly for many reasons or due to an error. Be sure to have another person hold the model down before connecting the battery or turning the power on.

5. Check whether the model responds correctly to the radio signals.

Maiden Flight

For the rst ight wait for a day with as little breeze as possible; the evening hours often offer calmer conditions The aircraft is designed to be handlaunched (always into wind). If you are a beginner to model ying, we strongly recommend that you ask an experienced modeler to help you for the rst few ights. The following instructions are for users to easily understand the process of taking off, making in ight adjustments and landing the model.

The instruction manual cannot address every situation that may occur, but it does explain common situations that occur which could be useful for you

when ying. Beginner iers should seek help of an experienced pilot through a friend, local club or nearby RC hobby retailer.

Using excessive control stick inputs can cause in undesired results. Control stick inputs should be small and slight until you have become familiar with the way the model behaves.

Section Four: Flying Your Model

1. Taking Off

Hold the plane facing into the wind and keep it level as you apply the throttle. Now throw it smoothly forward with the nose level or angled up no more than 30-degrees. After the take-off use the control sticks to keep the wings and fuselage level as the model gains altitude. If the battery isn’t fully

charged, the plane will not climb normally. Once you have climbed to an altitude of 100-130 feet (30-40 meters) high you can adjust the trim to make it y smoothly.

2. Adjusting the Trims

Even if you balance the plane properly on land, it may not y horizontally due to the wind or weight shift. To check the trim, once you have reached your

initial climb altitude, set the throttle to about ¾ power and let go of the control sticks. If the plane turns to the right, adjust the rudder trim control on your

transmitter to the left. If the plane continues to climb, adjust the elevator trim up. Adjust the rudder and elevator trim controls so that the plane will y straight and level when you let go of the control sticks. Be sure to adjust the trim only after the plane has reached an altitude of more than 130 feet (40 meters). Adjusting the trim when the plane is ying too low could cause it to crash.

3. How to Control the Plane

The most basic ight pattern for your new plane is an oval shape. Fly the plane in one direction at a safe altitude until you are familiar with the control

sticks. When moving in a straight line, slightly adjust the control sticks to keep the plane level. To turn to the left, move the rudder stick slightly to the left and note the plane’s reaction. It should begin turning to the left while also losing a little bit of altitude. To maintain its altitude in a turn a pull the elevator stick toward you slightly at the same time. To complete the turn let both sticks spring back to their neutral position. To turn to the right, move the rudder stick slightly to the right and pull the elevator stick toward you slightly at the same time. To complete the turn let both sticks spring back to their neutral position.

With the aircraft ying at an adequate altitude, check how it responds when the motor is switched off, so that you are familiar with its behavior during the

gliding process.

Avoid ying tight turns at rst, especially close to the ground, and in particular during the landing approach.

4. How to Land the Plane

You must land the plane before the battery is too low. It is always better to land safely some distance away than to risk a crash by forcing the model back to your feet.

In order to land the plane safely, have a friend rst check for any obstacles or people around the intended landing area. With the model ying into the

wind reduce the power so the model starts descending. Use the control sticks to keep the wings and fuselage level until it touches down.

You could damage the plane if it lands too steeply on its nose or hits a wing tip rst. Landing into the wind ensures the slowest possible landing and

least chance of damage.

5. After Your Flight

Immediately disconnect the ight battery and then turn off your transmitter. Inspect the model for any damage and realign the wings and tail if necessary. Completely recharge your battery according to the manufacturer’s specications before ying again.

Appendix A: The Basics of Model Flying

The basics of model ying

Any aircraft - whether model or “man-carrying” - can be controlled around three primary axes: the vertical axis, lateral axis and longitudinal axis.

Operating the elevator produces a change in the aeroplane’s ight attitude around the lateral axis (pitch).

Giving a rudder command turns the model around the vertical axis (yaw). If you move the aileron stick, the model rotates around the longitudinal axis (roll).

All three axes can be controlled regardless of the aeroplane’s ight attitude.

All aircraft are subject to external inuences, such as turbulence, which tend to disturb the aircraft, causing it to deviate from its intended ight path; the pilot’s task is then to apply control commands so that the model continues to y in the desired direction.

The power system (motor and propeller) provides control over rate of climb and speed. The rotational speed of the motor is innitely variable using the

speed controller, which follows your control commands from the transmitter.

The important point to note is that pulling up elevator by itself causes the model to climb, but only until it reaches its minimum airspeed. The aeroplane’s ability to climb at different angles depends on the power of the motor. If the model’s speed falls below its minimum airspeed, it tips forward and dives: this is known as stalling. This occurs when the airow which generates the lift required to keep the aircraft in the air is no longer attached to the wing, and the lift collapses.

The Sky Scout is designed in such a way that it exhibits very docile stalling characteristics, and loses very little height when it does stall. In this situation it drops its nose, immediately picks up speed, and is very soon under the pilot’s control once more.

If you are a beginner to model ying, we recommend that you initially control the Sky Scout using rudder and elevator only. To turn the model (initial turns and circles), use the rudder to set up a slight angle of bank, then apply gentle up-elevator to avoid the nose dropping during the turn. Always try to turn away from you at rst.

Once you have mastered basic control of the Sky Scout, it is time to try the ailerons. However, this does not mean that you can afford to forget the rud-

der. A smooth turn, i.e. one which makes efcient use of the airow, is always own best by co-ordinating rudder and aileron commands. This is a basic skill required to y any model aeroplane smoothly and accurately.

Without this level of co-ordination the Sky Scout will not y so efciently, although it is very tolerant of such abuse. However, if you concentrate on learning the art of ying smoothly right from the outset, you will nd it much easier to control more demanding models at a later date, and will be able to avoid

many a critical situation.

Concentrate constantly on moving the sticks slowly and gradually.

Abrupt, jerky movement of the transmitter controls often places the model in ight situations from which the beginner is unable to escape.

If this should happen, it is generally better simply to let go of the sticks and switch the motor off.

Wait a few moments until the model has “calmed down”, and you will then nd it easier to regain full control. If you cannot avoid a crash, at least the motor is stopped, minimizing the energy which has to be dissipated through the impact, and thereby limiting damage to the airframe.

As a beginner you are bound to nd it difcult to steer in the correct direction when the model is ying towards you. Learn this rule by heart: the

stick must be moved to the side where the “danger” lurks, i.e. move the stick towards the low wing, and “prop it up”.

We suggest that you learn these suggestions in the period before the rst ight, so that you are not surprised by the model’s behaviour when you are actually ying!

Wing section (airfoil)

The wing has a curved (cambered) cross-section, known as an airfoil, over which the air ows when the model is ying. In a given time the air above

the wing covers a greater distance than the air below the wing. This results in a reduction in pressure over the top surface of the wing, generating an

upward force (lift) which keeps the aircraft in the air.

Appendix A: The Basics of Model Flying

Centre of Gravity

Like any other aircraft, your model aeroplane must be balanced at a particular point if it is to have stable ying characteristics. It is absolutely essential to balance the model correctly before its rst ight. The balance point, or Centre of Gravity (CG), is stated as a linear distance measured from the wing leading edge, close to the fuselage. When supported at this point on your ngertips, or - preferably - using the MPX CG gauge, # 69 3054, the model should balance level. If the model does not balance at the marked point, this can usually be corrected by re-positioning the airborne components (e.g. ight battery). If this is not sufcient, the correct quantity of ballast (lead or modelling clay) should be xed securely to the nose or tail of the fuselage. If the model is tail-heavy, t the ballast at the fuselage nose; if it is nose-heavy, attach the ballast at the tail end of the fuselage.

Neutral point

The neutral point of an aircraft is the point at which the aerodynamic forces are in equilibrium.

If an aeroplane ies in a stable attitude, then its neutral point is always aft of the Centre of Gravity. Any aircraft whose Centre of Gravity is aft of the neutral point will be inherently unstable in the air. Manual control of an aircraft trimmed in this way is impossible; it requires a computer system for stabilization and control.

Longitudinal dihedral

This term refers to the difference in incidence between the wing and the tailplane.

Provided that you t and secure the Sky Scout’s wing and tailplane to the fuselage as stated in these instructions, then the longitudinal dihedral will

automatically be exactly correct.

If these two settings (centre of gravity and longitudinal dihedral) are correct, you will encounter no problems when ying your aeroplane, especially at the test-ying stage.

Control surfaces and control surface travels

The model can only y safely and precisely if the control surfaces are free-moving, operate in the correct “sense” (direction relative to stick movement), and are set up to deect by the appropriate amount. The control surface travels stated in the building instructions have been established by a test-ying programme, and we recommend that you adopt

these settings initially. You may wish to adjust them subsequently to suit your personal preferences.

Transmitter control functions

The radio control system transmitter is tted with two primary sticks which cause the servos - and therefore the model’s control surfaces - to deect when moved. The stated function assignment is correct for stick mode 2, but other stick modes are possible.

The following control surfaces are controlled from the transmitter:

The rudder (left / right) The elevator (up / down) The throttle (motor off / on) The ailerons (left / right) The stick which controls the throttle (motor speed) must not be of the self-centering type. It is usually tted with a ratchet which operates over the full stick travel.

How this setting works you can read up in the operating instructions supplied with your radio control system.

The Sky Scout is designed for success in a “3-channel” conguration using rudder, elevator and throttle control. This basic conguration is well suited

to beginners and relaxing ying. More experienced pilots may prefer to increase the performance of their Sky Scout by adding the optional aileron

controls. While the necessary hardware is included with your Sky Scout, two additional servos and two servo extensions are required. The mechanical

installation of the servos and aileron controls is detailed in the Assembly instructions in steps 8, 9, 24-28, beginning on page 8.

When installing the optional ailerons the rudder will be controlled by moving the left stick while the ailerons will be controlled by the right. Connect the

rudder servo cable to the receiver port labeled “4.” Plug the aileron servo extensions into receiver ports #1 & 5. The rudder should only be connected to

the receiver port #1 when ailerons are not used. If you are not comfortable doing this, please consult a local expert or your local RC hobby retailer.
