1. Your Turbo Beaver airplane should not be considered a toy, but rather a sophisticated, working model that functions very much like a full-size airplane. Because of its performance capabilities, the Turbo Beaver, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.

2. You must assemble the Turbo Beaver airplane according to the instructions. Do not alter or modify the model, as doing so may result in an unsafe or un yable model. In a few cases the instructions may differ slightly from the photos. In those instances the written instructions should be considered as correct.

3. If you are not an experienced pilot or have not  own this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for your  rst  ights. If you’re not a member of a club, your

Page 3

local hobby shop has information about clubs in your area whose membership includes experienced pilots.

4. Check the operation of the model and all components before each  ight.

5. DO NOT install the propeller UNTIL you have

completed ALL FOUR of the following steps!

A. You MUST con rm that the radio system is functioning

properly.

B. Understand the operation of the motor/failsafe/ESC

in all possible operation scenarios.

C. Learn how to properly power up and power down for

each  ight (see back page).

D. Complete all of the steps in this manual, prior to the

prop installation on page 18.

Install the propeller only AFTER you have completed these four steps.

While this kit has been  ight tested to exceed normal use, if the plane will be used for extremely high stress  ying, or if a motor or battery larger than ones in the recommended range is used, the modeler is responsible for taking steps to reinforce the high stress points and/or substituting hardware more suitable for the increased stress.

INTRODUCTION

REQUIRED TO COMPLETE

Thank you for purchasing the Flyzone 1/10th-scale de

Havilland DHC-2T Turbo Beaver Rx-R airplane. For anybody who enjoys  ying  oat planes or who aspires to do so for the  rst time, the Flyzone Turbo Beaver is the perfect choice because it  ies off the water so well—you virtually can’t mess up a takeoff or landing unless you try! Of course, the

Turbo Beaver is almost just as much at home on dry land

as it is in the water. And with the  aps extended you can set your Turbo Beaver down on water or on land as light as a feather.

For the latest technical updates or manual corrections to the Turbo Beaver airplane, visit the Flyzone site at www.  yzoneplanes.com. Open the “Airplanes” link, then select the “Turbo Beaver”.

IMPORTANT: Two of the most important things you can do to preserve the radio controlled aircraft hobby are to avoid  ying near full-scale aircraft and avoid  ying near or over groups of people.

Other than a #1 and #2 Phillips screwdriver, and a few drops of non-permanent threadlocker (GPMR6060), no adhesives or anything extraordinary is required to assemble the Turbo Beaver airplane.

Radio System

The model requires a transmitter and receiver with at least 5

channels. For an economical, digital 6-channel transmitter we recommend the Spektrum DX6 or DX6e. Both are budget friendly models loaded with options that are more than adequate for  ying this model. The Tactic TTX660 is another affordable computerized transmitter that would be a great choice. Part numbers are provided:

❍ Tactic TTX660 6-Channel Computer Transmitter

(TACJ2660)

❍ Tactic TR625 6-Channel SLT Receiver Twin Antennas

(TACL0625)

❍ DX6 6-Channel DSMX Transmitter Gen 3 with AR6600T

Receiver (SPM6755)

❍ Spektrum DX6e 6-Channel Radio with AR610 Receiver

(SPMJ1006)

Battery and Charger

A 3S 11.1V LiPo battery is required. A commonly used 2200mAh sized pack provides a good balance between  ight time and performance. A charger capable of safely charging LiPo battery chemistry is also required. Onyx and Dynamite both offer a variety of models from your basic, economically priced chargers all the way to your highend, feature rich models that will accommodate all of your foreseeable charging needs.

❍

11.1V 2200mAh 3S 30C LiPo, EC3 (EFLB22003S30)

❍

F-Tek 2200mAh 3S 11.1V 40C LiPo EC3 LED (KXSB22003S40)

IMPORTANT: connector. If your charger does not include EC3 charge leads, they can be purchased separately using part number EFLAEC312.

ASSEMBLY

It’s your choice to install either the landing gear or the  oats. Start the assembly after making this decision.

Mount the Landing Gear

Use a #2 Phillips screwdriver to fasten both main landing

❑

gears to the fuselage with three M3x16 screws in each side.

Mount the Floats

2. Mount the tail gear with two M2.5x8 screws, then fasten

❑

the pushrod wires as shown. Make sure the tail wheel is perpendicular with the steering arm and tighten the screws.

1. Connect the  oats to each other with the horizontal

❑

struts and four M2.5x20 machine-thread screws.

Page 7

2. Use eight M2.5x8 screws to fasten the braces to the

❑

 oats, matching the labels printed or molded into the end of each brace to each mount location on each  oat.

4. Connect a small rubber band to the inside side of

❑

each  oat and water rudder as shown.

5. Fasten the wire hooks on the end of each rudder

❑

line to the connectors in the steering arm. As best as you can, adjust the tension in the lines to center the water rudders—the rudders don’t have to be perfectly centered, because over time they may drift anyway, and the rudders are forgiving and overall water handling is easy.

TIP: One of the wire hooks will need to be bent up some

to not interfere with the other hook.

3. Fasten the  oat braces to the fuselage with one

❑

M3x16mm screw and two M2.5x8mm screws in each side of the fuselage. No screw is installed in the third strut at this time.

Page 8

Mount the Horizontal

and Vertical Stabilizer

1. Fasten the vertical stabilizers to each end of the

❑

horizontal stabilizer (stab) with M2x6 screws.

2. Connect the elevator pushrod to the bottom hole in

❑

the elevator horn as shown.

3. Rotate the stab upward and key it into the fuselage.

❑

4. Key the rudder torque rod down into the receptacle

❑

while  tting the vertical stabilizer ( n) into the fuselage.

Tightly press the assembly down into position.

Page 9

5. Secure the stab and  n with the M3x22 screw.

❑

Mount the Wings

1. Fasten the wing clips to both sides of the fuselage

❑

with four M3x10 screws.

Guide the wires from the right wing into the fuselage,

❑

then slide the wing joiner tube and the  ap pushrod wire through the corresponding holes. Also guide the  ap pushrod wire into the screw-lock connector on the  ap servo. Guide the joiner tube through the hole in the left side of the fuselage, then tightly “CLICK!” the wing onto the wing clips.

Page 10

3. Mount the left wing the same way.

❑

Install the Battery

1. Cut two 1" [25mm] strips from the rougher, “hook”

❑

side of the included adhesive-back hook-and-loop material. Apply the strips inside the fuselage where shown and press them down tightly so they adhere.

4. Mount the top of each wing strut to the wing with a

❑

M2.5x8 machine-thread screw.

2. Cut a 3" [ 76 mm] strip from the softer, “loop” side and

❑

attach it to the battery so the larger “discharge” wires will be on the right side as shown. (This will position the wires opposite the receiver for a better  t.)

Mount the bottom of each strut to the fuselage over

❑

the third  oat strut (or over the main landing gear) with a M3x16 screw.

Page 11

Receiver Installation

Install your receiver into the fuselage, connecting the servos according to the labels attached to the wires. Follow the radio manufacturer’s recommendations for set-up.

WARNING: DO NOT INSTALL THE PROPELLER

UNTIL THE RADIO SYSTEM HAS BEEN PROPERLY SET UP WITH A WORKING FAILSAFE FUNCTION AND YOU COMPLETELY UNDERSTAND ITS OPERATION!

preset position. This prevents the possibility of accidental motor startup when the  ight battery is connected but the receiver is not communicating with the transmitter.

If using the recommended Tactic radio system, follow these instructions for setting up and con rming the operation of the failsafe function. Setting the throttle failsafe position is similar for Spektrum radios. The failsafe is set during the binding process to the receiver. NOTE: Unlike Tactic, Spektrum radios will not require the throttle channel to be reversed. Continue on to Te s ting

the Failsafe section when complete.

Tactic Failsafe Procedure

Throttle stick is in the 0% (minimum) position!

Connect the wing lighting wires to the light wire harness

❑

in the fuselage (marked L1 and L2). The receiver end can be connected to BATTERY or any unused channel slot on your receiver. Connect the aileron servo wires to the Y-harness that was included in the hardware bag and connect the

Y-harness to the aileron channel on your receiver.

Failsafe Setting and Function

IMPORTANT: Before installing the propeller, it’s important for safety reasons to ensure that the failsafe on the receiver is at the 0% throttle preset position as indicated in the instructions below.

Most modern radio systems have a failsafe feature which engages in the event that the radio signal from the transmitter is interrupted. If radio contact is broken, this safety feature causes the throttle channel to move to a

1. Make sure the throttle stick is in the minimum position or 0% throttle.

3. Make sure the servo reversing function for CH3 is in the REVERSE position.

5. Press the LINK button on the Tactic receiver and hold for 2 seconds. The red LINK light should blink and then stay on. The failsafe is now set.

2. Power on the transmitter.

4. Plug in the

battery to the aircraft.

Testing the Failsafe

Before continuing, it is necessary to test the failsafe setting. First, move the right transmitter stick to the left and right and con rm that the transmitter is linked to the receiver. You should see the ailerons moving. Remember, the propeller is not installed on the motor yet! Move the throttle stick up and con rm that the motor is working. While the motor is spinning, turn the transmitter OFF to test the failsafe function. The motor should stop. If it does not stop spinning, DO NOT CONTINUE until the

failsafe works correctly.

Page 12

ESC Operation/Startup

Starting Your Power System

1. Turn on your transmitter and ensure the position of the throttle stick is set to Idle/Off.

2. Plug the battery pack into the controller. You will hear

1 low l ong tone to indicate startup, the n the r especti ve

number of medium-length mid tones to indicate the cell count or a musical tone for the 70% cutoff, followed by 3 rising tones to indicate the controller is armed.

3. When you move the throttle stick upward, the motor will run. If you continue to move the throttle stick upward to the full throttle (high position), the motor will run faster. If you lower the throttle stick below the start-up position, the motor will stop running.

4. Check servo motion as part of your pre ight check. It is very important you make sure linkages are freemoving with no binding.

Remember, when in the programming mode:

Full Throttle = Stick Up Idle = Stick Down

The default settings (from the package) for your E- ite

40-Amp Pro ESC are as follows:

• Voltage cutoff set at 70%

• Brake set to Off

• Timing set at 15 degrees

• Throttle Input Range set at 1.2ms to 1.8ms

• Start-up Rate (Acceleration Delay) set at 0.25 seconds

• PWM Frequency set at 8kHz

• Operating Mode set to normal (airplane)

Entering the Programming Mode

1. With the battery disconnected from the controller, and the transmitter turned on,  rst move the throttle stick to full throt t le (>1.7ms) pos ition. Leave it in th is pos ition and then connect the battery to the controller.

2. Wait for 5 seconds, and the ESC will give two sets of fast ringing tones to indicate you have successfully entered the programming mode.

3. Once you hear these tones, move the stick to center

(between 1.4 and 1.7ms) for 5 seconds, and the controller will beep 1 time, indicating you are now in Menu 1.

4. The controller will now wait 5 seconds for you to make

your selection; your programming options are either

full throttle (>1.7ms) or idle (<1.3ms).

5. When you have made a valid selection, the control will beep once with a lower tone, and you can move the stick back to center for the next menu item (2 beeps, 3 beeps and so on). If you do not make a selection

within 5 seconds, the controller will move to the next

menu item.

6. If you want to make changes in the programming menus

(see speci c instructions below) move the throttle stick

to full throt t le (>1.7ms) posi tion. You w ill h ave 5 seco nds to make your selection.

7. If you want to advance to the next menu, allow the programming to skip to the next menu after the 5 seconds have expired.

Programming Menu 1 – Voltage Cutoff

Use this option to set the voltage at which the controller wi ll shu t dow n the moto r to p reve nt da m age to you r batter y when it reaches the cutoff voltage. You will know your battery pack has reached auto cutoff when you hear the motor “pulse” repeatedly.

1. Move the throttle stick to full throttle (>1.7ms) position to make changes to the voltage cutoff programming.

a. To select 3-cell low voltage cutoff – You will hear

3 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

b. To select 4-cell low voltage cutoff – You will hear

4 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

c. To select 5-cell low voltage cutoff – You will hear

5 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

d. To select 6-cell low voltage cutoff – You will hear

6 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

e. To select 70% cutoff – You will hear 7 short beeps.

Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in

full throttle for 5 seconds to advance to the  rst selection again.

IMPORTANT NOTE ABOUT 70% CUTOFF: This option will activate the soft cutoff at 70% of startup voltage. For example, if your pack measures 15.0 volts at startup, then the soft cut will occur at 10.5 volts. The 70% cutoff option will check the startup voltage every time you plug the battery into the controller, so beware of using partially charged packs, as the system cannot protect your Li-Po batteries if you are using the 70% cutoff and connect a partially charged pack. You will know your battery pack has reached soft auto cutoff when you hear the motor

“pulse” repeatedly. We recommend you land your model

as soon as you hear the motor pulse (indicating the pack voltage has dropped to the cutoff voltage level) to prevent over-discharge of the Li-Po battery pack, and to prevent sudden power loss.

Programming Menu 2 – Brake Type

The default setting is Brake Off. This option gives you the

choice to have the ESC stop the propeller during  ight (Brake On) or allow it to windmill (Brake Off). Use the Brake On options for folding propellers.

1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 2 times, indicating

you are now in Menu 2.

2. Move the throttl e stic k to f ull t hrottle (>1.7ms) p ositi on to make changes to the Brake Type programming.

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

b. To select Soft Brake – You will hear 2 short beeps. Move

the throttle stick to center (between 1.4 and 1.6ms).

The controller will beep 2 times, indicating you have set

the program selection or leave in full throttle for 5 seconds to advance to the next selection.

c. To select Medium Brake – You will hear 3 short beeps.

Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

d. To select Hard Brake – You will hear 4 short beeps. Move

the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicatin g you have s et the program selection or leave in full throttle for 5 seconds to advance to the  rst selection again.

Programming Menu 3 – Timing

full throttle for 5 seconds to advance to the  rst selection again.

Programming Menu 4 – Throttle Input Range (PWM)

The default setting is 1.2ms to 1.8ms and should work

with most radio systems. This option allows for proper throttle input with many different radio systems. However, some radios have a wider output range, and may give a more linear response with the 1.1ms to 1.9ms range. If you feel there is too much “dead” area in the stick movement near full throttle, try adjusting the end points in your radio, or change to the wider input range. Be aware that if these settings are not correct, it may be impossible to arm the controller.

1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 4 times, indicating you are now in Menu 4.

2. Move the throttl e stic k to f ull t hrottle (>1.7ms) p ositi on to make changes to the Throttle Input Range programming.

a. To select 1.2ms to 1.8ms – You will hear 1 short beep.

Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

b. To select 1.1ms to 1.9ms – You will hear 2 short beeps.

Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the  rst selection again.

b. To select 16kHz PWM Frequency – You will hear 2 short

beeps. Move the throttle stick to center (between 1.4 a nd

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

c. To select 32kHz PWM Frequency – You will hear 3 short

beeps. Move the throttle stick to center (between 1.4 a nd

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the  rst selection again.

Programming Menu 5 – Start-Up Rate

The default setting is 0.25 seconds. The start-up rate is the

time it takes to reach maximum motor speed. Changing the setting to 1 second can be useful with power-fragile gear boxes.

1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 5 times, indicating

you are now in Menu 3.

2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the Start-up Rate programming.

a. To select .25 second – You will hear 1 short beep. Move

b. To select 1 second – You will hear 2 short beeps. Move

Programming Menu 6 – PWM Switching Frequency

The default setting is 8kHz, which should be acceptable

for most motors. If you have a low or very low inductance motor and know you need to use a higher PWM Frequency (refer to the manual included with the motor), then you can change the setting. Otherwise, we recommend leaving the default setting.

1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 6 times, indicating

you are now in Menu 6.

2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the PWM Switching Frequency programming.

a. To select 8kHz PWM Frequency – You

will hear 1 short beep. Move the throttle

stick to center (between 1.4 and 1.6ms).

The controller will beep 2 times, indicating you have

set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

Programming Menu 7 – Operating Mode

The default setting is set to Normal (airplane) Mode, which

is limited to a start-up rate of 0.25 or 1 second. Alternatively, the Heli Mode can be selected which reduces the start-up rate to 5-seconds for the  rst start-up and any start-up after the motor/ESC has been stopped for more than 5 seconds. This helps to prevent damaging the motor, gears or any other components from an abrupt start-up when none of the parts are moving. Any time the motor/ESC has been stopped for less than 5 seconds in Heli Mode, the start-up will be immediate. This allows power to be applied im-mediately, such as when aborting an autorotation attempt or for any other reason, to help prevent a crash. Remember, you must wait more than 5 seconds after stopping the motor/ESC in order for the 5 second start-up to occur again.

1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 7 times, indicating you are now in Menu 7.

2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the Operating Mode programming.

a. To select Normal Mode – You will hear 1 short

beep. Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

b. To select Heli Mode – You will hear 2 short beeps.

Move the throttle stick to center (between 1.4 and

1.6ms). The controller will beep 2 times, indicating

you have set the program selection or leave in

full throttle for 5 seconds to advance to the  rst selection again.

1. Turn on the transmitter, lower the throttle stick all the

❑

way to 0%, and center the trims.

3. Remove the screw from the connector on the elevator

servo arm.

2. Connect the battery to the ESC. The motor will emit a

❑

series of tones indicating the cell count of the battery and a rising series of tones indicating the ESC is now armed.

WARNING: Make sure this propeller is not installed for this next step.

A magnetic screwdriver, or a small magnet stuck to a screw driver to make it magnetic, will be helpful for the next couple of steps.

4. Lightly wet the threads of the screw with threadlocker.

❑

5. Reinstall the screw, but do not tighten yet. With the

❑

transmitter and receiver on, center the elevator and tighten the screw to lock the pushrod down.

Page 16

6. Repeat the same procedure for the rudder, making

❑

sure it is centered. Lock the pushrod in place on the servo arm with the screw and threadlocker.

7. Move the dial or switch on your transmitter that

❑

controls the  aps to the “up” position, rotating the  ap servo arm clockwise. Remove the screw in the  ap servo arm, wet the threads with threadlocker, and then reinstall and tighten the screw so the  aps will be in their fully retracted (“up”) position.

4. With the system still on, make sure the ailerons are

❑

centered and aligned with the wing tips. If necessary, apply a few clicks of aileron trim to get the ailerons centered. If more than a few clicks of trim are required, or if you cannot get both ailerons neutralized, a small screwdriver may be used to pop off one or both aileron servo covers to access the pushrods. Adjust the pushrods in the connectors to get the ailerons centered. When  nished, replace the cover, press into position, and hold in place with tape or a dab of glue.

5. Test  t the battery hatch onto the fuselage.

Check the Control Throws

Because the servos and pushrods are factory-installed the control throws should already be correct, but because of the effect the control throws can have on a model, it’s always a good idea to check them anyway.

4. If any of the control throws require adjustment use the

❑

programming in your transmitter to increase or decrease the throws accordingly. If the programming isn’t enough or if your radio doesn’t have adjustable throws, the pushrod connectors on the servo arms can be relocated in different holes inward or outward to increase or decrease the throw— moving the pushrods inward on the servo arms decreases the throw and moving the pushrods outward on the servo arms increases the throw.

Motor and Prop Safety Precautions

WARNING: FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS MAY RESULT IN SEVERE INJURY

TO YOURSELF AND OTHERS.

Mount the Propeller and Spinner

CAUTION: Do not proceed with propeller installation until you have con rmed the correct

operation of the throttle failsafe on page 11!

WARNING: DISCONNECT THE BATTERY PRIOR TO DOING ANY MAINTENANCE TO THE MOTOR!

1. Install the prop shaft and drive washer onto the motor

❑

shaft.

● Wear safety glasses whenever in the proximity of a spinning propeller.

● Do not operate the motor in an area of loose gravel or sand; the propeller may throw such material in your face or eyes.

● Keep spectators as well as your own face and body out of the plane of rotation of the propeller.

● Never connect the battery to the ESC while indoors with the propeller installed.

● Always remove the propeller when testing or making repairs to the model.

● Always stay behind the arc of the propeller when handling the model.

● Always assume the motor may start unexpectedly when the  ight battery is connected.

● Always remain outside the arc of the propeller when installing and/or removing the  ight battery.

● Keep all loose clothing, long hair or any other loose objects such as pencils or screwdrivers that may fall out of pockets away from the propeller.

2. Secure the propeller, washer and nut. Make sure the

❑

assembly is secure to the aircraft.

2. Install the spinner cone with a M3x8 machine screw.

great effect on how every model  ies, so do not skip this procedure. If the model is tail-heavy it may be too unstable and respond too quickly to the controls. If the model is noseheavy it may be too stable and not respond fast enough to control input—in either case possibly causing a crash. Do not overlook this important procedure.

Same as the control throws, the C.G. has a

CAUTION: When checking the C.G., the battery should be installed, but remain DISCONNECTED.

4. Lift the model by your  ngers between the lines

❑

indicating the balance range. As long as the model sits level with your  ngers on the forward or aft lines or anywhere between the lines it is properly balanced and ready to  y. If you have to move your  ngertips outside the lines the model is out of balance and should not be  own. If necessary, add squares of stick-on lead to the nose or tail to get the model to balance within the speci ed range.

1. Mark the forward and aft C.G. limits on both sides of

❑

the bottom of the wing 2" and 2-1/2" [51mm and 64mm] back from the leading edge where shown—using narrow strips of tape will allow you to feel the marks when lifting the model with your  ngertips to balance.

2. Install the battery, battery hatch and cabin hatch.

❑

At this point the model must be in ready-to- y condition

FLYING

When powering up, make sure the throttle stick is in the minimum (0%) position. Always turn the transmitter ON before plugging the battery into the plane.

The Turbo Beaver model  ies mostly the same as any similar-

type, high-wing airplane, but you may  nd that the roll rate is a little slower. This suits the Turbo Beaver well as it is a scale-like, STOL (Short TakeOff and Landing) craft. Just give yourself more time and altitude before trying your  rst full roll.

The only peculiarity arises when the  aps are extended—if

you extend the  aps too soon before the model has lost enough  ying speed the nose will pitch up. The way to avoid this is  rst by making sure you have given the model enough time to slow after cutting the throttle. You can also roll in the  aps gradually. If you have a computer radio you could also mix in some down elevator with  aps. In any regard, once the model reaches “equilibrium” and has initiated a gliding descent the nose will resume a normal, downward glide angle. Similarly, when powering up the throttle with the  aps extended the nose will pitch up, so be ready to counter with down elevator.

Unless weather conditions are poor, you should have no trouble  ying the Turbo Beaver plane from either rough or calm water. The water rudders direct the model well and they don’t have to be perfectly centered to be effective (so don’t spend an exorbitant amount of time on the work bench

Page 20

working on them!). The model turns more tightly at idle speeds, so if you need to do a U-turn, throttle back to bring the model around. At higher speeds during a takeoff run the water rudders have the correct amount of effectiveness to steer the model on its intended path. Takeoffs can be long and graceful or short and steep—either way the  oats handle the water well. If the winds are really high the model can still be  own from water, but avoid turning it directly across the wind. Otherwise, the wind can get under the wing and  ip the model over. In the air, the only effect of the  oats is that the model  ies slightly slower.

Flying “normally” (using half-throttle for general cruising and full-throttle only when required) the Turbo Beaver model can get as much as 8 minutes of  ight time using a 2200mAh battery. Flying more aggressively using consistently higher throttle settings will increase the current draw from the battery and reduce  ying time.

To  nd out for yourself how long you can  y, set your timer

to a conservative 5 minutes. Fly until the timer sounds, then land. Use a charger with a digital display to  nd out how much capacity it took to recharge the battery (indicating how much capacity was used). To avoid over discharging your LiPos use only 80% of your battery’s capacity, so multiply your battery’s capacity by .8 to  nd out how much you have available. Compare the capacity used to 80% of your battery’s capacity and adjust your  ight time accordingly.

For example: If using the recommended 2200mAh battery, your target capacity to use for a  ight is 1760mAh (2200mAh x .8 = 1760mAh). If you  y for  ve minutes and it takes

1400mAh to recharge your battery, you still have 360mAh to

go before you should land, so adjust your timer to increase your  ight time accordingly until you reach your 1760mAh target. (You could also divide 1400mAh by  ve minutes to  gure a current consumption rate of 280mAh/minute. Divide

1760mAh by 280mAh/minute to conclude that you can  y

for 6.3 minutes—but round down to 6 minutes.)

When powering off, always unplug the battery from the plane before turning the transmitter OFF.

REPAIRS

Parts damaged beyond repair can be purchased separately.

The full replacement part list is printed in the front of the

manual on page 4. Often though, parts can be repaired and you can get your plane back into the air with a little glue and ingenuity.

This model is made from injection-molded EPO (expanded

polyole n) foam which can be glued with just about anything. Most people use regular CA. With CA no clamping is required, but some prefer softer, more  exible adhesives such as white glue or canopy glue. These will require clamps or tape to hold the parts together while the glue dries.

One  nal note about  ying your model. Have a goal or  ight plan in mind for every  ight. This can be learning a new maneuver(s), improving a maneuver(s) you already know, or learning how the model behaves in certain conditions (such as on high or low rates). This is not necessarily to improve your skills (though it is never a bad idea!), but more importantly so you do not surprise yourself by impulsively attempting a maneuver and suddenly  nding that you’ve run out of time, altitude or airspeed. Every maneuver should be deliberate, not impulsive. For example, if you’re going to do a loop, check your altitude, mind the wind direction (anticipating rudder corrections that will be required to maintain heading), remember to throttle back at the top, and make certain you are on the desired rates (high/low rates). A  ight plan greatly reduces the chances of crashing your model just because of poor planning and impulsive moves. Remember to think.

Have a ball! But always stay in control

and  y in a safe manner.

GOOD LUCK AND GREAT FLYING!

It’s also a great idea to use a LiPo battery checker such as the E- ite LiPo Vell Voltage Checker (EFLA111) to check the battery before each  ight (to make sure you haven’t inadvertently grabbed a discharged battery) and to check the battery after  ight to make sure you haven’t over discharged your battery by  ying too long. A safe, conservative, minimum voltage is 3.65V – 3.7V per cell right after a  ight.
