H-KING CESSNA TTX

INSTRUCTION MANUAL

INTRODUCTION.

The H-King Cessna TTX is an excellent, scale rendition of the original plane
made by Cessna. It is made of tough EPO foam and is beautifully crafted with
panel lines and scale cockpit and other details. Plenty of power with the scale
3-blade propeller.

The Cessna TTX is a single-engine, low wing, general aviation plane with a
fixed tricycle undercarriage and was produced between 2004-2018 by Cessna
Aircraft. It was originally called the Cessna 400. It was designed to carry a pilot
and three passengers.

At 1100mm wingspan the TTX is small enough to transport fully assembled but
if you need to take the wings off it is extremely easy with the new wiring quick­connectors. Take-offs and landings are a breeze thanks to the scale slotted
flaps and the super bright navigation lights will allow everyone to easily spot this
streamlined plane. With a thrust ratio of 1:1.3 there is no trouble doing some
easy rolls and loops and other maneuvers. The large hatch area makes
installing a battery so easy.

This is a beautiful, scale plane which will have you the talk of the field.

SAFETY INSTRUCTIONS

1. Please read this manual carefully and follow the instructions
before you use this product.

2. This airplane is not a toy, due to it's advanced flying qualities it
is only suitable for pilots with intermediate or higher experience.
If you are a novice then please only operate with the assistance
of an experienced pilot.

3. Not recommended for children under 14 years old.

4. Please set up this plane according to the instructions and

make sure you keep your hands and other parts of your body out
of the way of the rotating propellers at all times. Failure to do so
will result in damage to yourself and to the airplane.

5. Do not fly in thunderstorms, strong winds or wet weather.

6. Never fly R/C planes where there are overhead power lines,

automobiles, airports, railway lines or near a highway.

7. Never fly R/C planes where there are crowds of people or
over organised games. This airplane requires a very flat landing
and take-off area or lake that is clear of tree's and other
obstacles. Remember safety is the responsibility of the pilot.

8. Do not attempt to catch the plane when you are flying it.

9. The operator will bear the full responsibility of flying and the

proper operation and usage of this model. We at Hobbyking will
not be responsible for any liability or loss due to improper use of
this model.

CESSNA TTX

Step 1: Clip the undercarriage into the slot in the fuselage,

squeeze the legs together slightly so that it fits into the slot. Once

in place remove the pressure and it will hold in place, no retaining

screws are required.

Step 2: Apply some medium or slow setting CA glue to the cut out in

the rear of the fuselage and glue into place the horizontal stabilizer.

Attach the elevator clevis to the control horn when glue has set.

Step 3: Apply medium or slow setting CA glue to the rudder hinges then

slide the rudder into the slots in the vertical stabilizer. Once glue has set
attach the rudder clevis to the control horn.

Step 4: Attach the wings using the 2 M3 x 20mm hex

head screws provided. Note that the aileron and flap

servos connect automatically and so does the wing

LED's, see pictures below.

Step 5: Using a medium CA glue in place the scale

antenna into the slot in the top of the fuselage.

Step 6: Glue into place the 2 scale footrests

either side of the fuselage just behind the wing

using a medium CA glue.

Step 7: Attach the 3 bladed propeller and spinner as shown. Remove the nut

and washer from the shaft, fit onto the prop shaft first the spinner backplate

and then the propeller. Refit the nut and washer and tighten. Next fit the

spinner cone over the propeller and hold in place with the M3 x 10mm screw

provided. This finishes the construction so all you need to do now is fit your

receiver and battery.

Center of Gravity.

The C of G position is between 35mm and 40mm from the wing leading edge,

see picture below. For first flights we recommend you start near the forward

position then as you get used to the handling of the model you can move it
towards the rear position. On or near the forward position the model will be

very smooth and stable, as you move the C of G back it will become more

aerobatic and slightly less stable in pitch. Move the battery forwards or

rearwards to achieve your preferred C of G.

Suggested Control Throws.

Ailerons: 9mm each way (measured at the tip).

Elevator: 6mm each way (measured at the tip)

Rudder: 10-12mm each way.

Flaps: 1st stage 8mm, 2nd stage 22-24mm (measured at the root).

Flying.

We shall not delve too much into flying the Cessna TTX as it is not a model designed
for beginners but for the model pilot who has flown low wing type aircraft before.

Before flying first thing is to double check all the controls are moving in the correct
direction and the control throws have been set to approximately the suggested
movement. Re-check the C of G position and then do a range check of the radio.
Please ensure that you have a fully charged battery installed.

For intial flights it is best to leave the flaps alone, once you have flown the model a few
times you can then experiment with stage 1 for take-off and stage 2 for landings. Line
the model up into wind on your runway with a touch of up elevator and smoothly open
the throttle keeping it straight with the steerable nosewheel. The Cessna has an
abundance of power so will lift off very readily and climb away rapidly gaining height.
Once at a safe height explore the delightful handling characteristics of the Cessna
TTX. It is very smooth and aerobats very nicely, a very pleasing aeroplane to fly that
will put a smile on your face.

Landings really are a non event, the plane virtually lands itself. Fly a nice circuit at
reduced power and when on finals take most of the power off and glide onto you
landing area controlling the airspeed with the elevator. At about shoulder height or a
bit less start to very gently raise the nose with a small amount of elevator until you are
flying level with the ground at about half a wingspan. Keep very gently pulling back the
elevator until the rear wheels kiss the ground and you have landed.

The flaps are quite powerful, best to get used to them up high to start with to watch the
attitude change and to get used to the handling, do not select the landing flap at high
speeds, slow the model down before selecting. Technique for landing with flaps is
much the same as flapless but you will need to have a bit more power on to overcome
the drag of the flaps. The round out, float and flare will also be shorter due to the drag
so watch out for this to avoid a heavy landing.

We hope you enjoy flying your H-KING Cessna TTX and if you haven't already tried
out the others in our range then we recommend you visit our website at
www.hobbyking.com and take a look at our ever increasing range of quality model
aircraft and accessories.

Have fun.
