Control Throws

 Step 1

Check the battery voltage on both the transmitter and

the receiver battery packs. Do not fly below 4.3V on the

transmitter if you are using a Spektrum transmitter that uses

4-cells to power the transmitter. Do not fly below 9.5V on the

transmitter if you are using a JR or Spektrum transmitter that

uses 8-cells to power the transmitter. Do not fly if the receiver

pack is at or below 4.7V. To do so may crash your aircraft.

 Step 2

Check the movement of the elevator with the radio system.

Moving the elevator stick toward the bottom of the

transmitter will make the airplane elevator move up.

 Step 3

Check the movement of the ailerons with the radio system.

Moving the aileron stick right will make the right aileron

move up and the left aileron move down.

 Step 4

Use a ruler to adjust the throw of the elevator, ailerons

and rudder.

Aileron High Rate

Up 3/8-inch (10mm) (14 degrees)

Down 3/8-inch (10mm) (14 degrees)

Aileron Low Rate

Up 1/4-inch (6mm) (8 degrees)

Down 1/4-inch (6mm) (8 degrees)

Elevator High Rate

Up 1/2-inch (13mm) (16 degrees)

Down 1/2-inch (13mm) (16 degrees)

Elevator Low Rate

Up 5/16-inch (8mm) (10 degrees)

Down 5/16-inch (8mm) (10 degrees)

Rudder High Rate

Left 7/8-inch (22mm) (20 degrees)

Right 7/8-inch (22mm) (20 degrees)

Rudder Low Rate

Left 1/2-inch (13mm) (11 degrees)

Right 1/2-inch (13mm) (11 degrees)

Note: Measurements are taken at the inner or widest

point on the control surface.

These are general guidelines measured from our own flight

tests. You can experiment with higher rates to match your

preferred style of flying.

Note: Travel Adjust, Sub-Trim and Dual Rates are

not listed and should be adjusted according to each

individual model and preference.

Once all control throws are set, make sure the

safety tubing is slid over the forks of the clevises to

prevent them from opening accidentally in ight.

Maintaining Your Model

The following is a check list you should follow every time you

have completed a flying session with your model. Doing so will

keep your aircraft in the best flying condition.

Clean Up

After a long flying session with your model, you will want to

clean it up before loading it into your vehicle to head home.

Use cleaner and a paper towel to wipe down the exterior of

your plane, removing the fuel residue. Remember, a clean

plane will last longer since the fuel won’t be allowed to soak

into any exposed wood.

Checking the Propeller

Check to make sure the propeller is tightly secured to the

engine. If not, remove the spinner and use a crescent wrench

to tighten it back down. If you have had any not-so-great

landings, you will want to inspect the propeller for any

damage. Small nicks and scratches can quickly become

fractures, causing the propeller to be unsafe for flight.

Always carry a few spare propellers so a damaged propeller

can be replaced at the field, increasing your flying time per

trip to the field.

Checking the Clevises

Inspect the aileron, elevator and rudder clevises to make

sure they are connected and in good working order. If you

find a clevis is showing signs of wear or broken, replace it

with a new clevis. Also check the nylon connectors at the

servo for any wear or damage. If they look worn or in bad

shape, replace them as well.

Checking the Control Horns

Inspect the control horns to make sure they have not

crushed the wood of the control surface. If so, remove the

control horn screws to remove the control horn. Place 2–3

drops of thin CA into each of the screw holes. In addition,

use a T-pin to poke small holes in the covering in the area

where the control horn mounts, then saturate the area with

thin CA. This will harden the wood and give the control

horns a solid surface to be mounted to.

Checking the Wheel Collars

Check the setscrews on the wheel collars for the main and

tail wheel to make sure they are not loose. Use a 1.5mm hex

wrench to tighten the setscrews. It is suggested if they loosen

frequently to remove them, apply threadlock to the setscrews,

then secure the wheel collars back into position. The threadlock

and hex wrench are included in the kit for this purpose.
