3. Make certain that the control surfaces and the throttle

respond in the correct direction as shown in the diagram.

If any of the controls respond in the wrong direction, use

the servo reversing in the transmitter to reverse the servos

connected to those controls. Be certain the control surfaces

have remained centered. Adjust if necessary.

Set the Control Throws

To ensure a successful first flight, fly your model set up only

according to the C.G. and control surface throws specified in

this manual. The throws and C.G. are not arbitrary, but have

been determined through extensive testing and accurate

record-keeping. This provides you with the best chance for

success and enjoyable first flights that should be surprise-

free. Additionally, the throws and C.G. shown are true, real

data which will allow the model to perform in the manner in

which it was intended when flown by a pilot of the skill level

for which it was intended. DO NOT OVERLOOK THESE

IMPORTANT PROCEDURES. A model that is not properly

setup may be unstable and possibly unflyable.

The building steps earlier in this manual that show the

mechanical setup for the elevator, rudder, and aileron

linkages show you the best way to configure the linkages to

achieve the proper throws using Futaba servos and a Futaba

radio system. If you are using a different radio system or

you cannot achieve the proper control throws using our

suggested linkage configuration, you may have to install the

pushrods in different holes on the servo arms or the control

horns. Keep in mind that changing the throws mechanically

is preferred to changing them using your radio’s end-point

adjustment. End points can be used to “fine-tune” to get the

proper throws.

❏

1. Use a Great Planes AccuThrow

™

gauge, a ruler, or an

inclinometer to accurately measure and set the control throw

of each control surface as indicated in the chart that follows.

If your radio does not have dual rates, we recommend

setting the throws at the LOW rate setting. Under normal

circumstances, and if you have both high and low rates set

up, you will perform takeoffs and landings using high rate

aileron and elevator and then switch to low rates for flight.

With this model, we recommend using high rate rudder only

during taxi on the ground. Switch to low rate rudder before

you initiate your takeoff.

❏

2. When setting up flaps for this model, please use only

the amount that we suggest below. This is the right amount

required to slow the model down without causing it to balloon

up excessively.

These are the recommended control surface throws:
