E-flite Super Cub 25e ARF Assembly Manual

Control Throws

1. Turn on the transmitter and receiver of your

model. Check the movement of the rudder using

the transmitter. When the stick is moved right, the

rudder should also move right. Reverse the direction

of the servo at the transmitter if necessary.

2. Check the movement of the elevator with the

radio system. Moving the elevator stick toward the

bottom of the transmitter should make the airplane

elevator move up.

3. Check the movement of the ailerons with the

radio system. Moving the aileron stick right should

make the right aileron move up and the left

aileron move down.

4. Use a ruler to adjust the throw of the elevator,

ailerons and rudder. Adjust the position of

the pushrod at the control horn to achieve the

following measurements when moving the sticks to

their endpoints.

The Super Cub benefits greatly from having aileron

differential. The suggested DX8 transmitter has a

provision for this that will allow you to set this up

without adjusting your ailerons travel volumes. The

differential on the DX8 should be set at 80%. This

setting should allow the travel measurements to match

these below. If not using a DX8, you can also set the

travel adjustment to match the suggested throws.

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.

Travel Adjust and Sub-Trims are not listed

and should be adjusted according to each

individual model and preference.

We highly recommend re-binding the radio

system once all the control throws are set. This will

keep the servos from moving to their endpoints

until the transmitter and receiver connect.

Check your Radio

Before going to the field, be sure your batteries are

fully charged per the instructions included with your

radio. Charge the transmitter and motor battery

for your airplane. Use the recommended charger

supplied with your particular radio system, following

the instructions provided with the radio. In most

cases, the radio should be charged the night before

going out flying.

Before each flying session, be sure to range check your

radio. See your radio manual for the recommended

range and instructions for your radio system. Each

radio manufacturer specifies different procedures for

their radio systems. Next, run the motor. With the

model securely anchored, check the range again.

The range test should not be significantly affected. If

it is, don’t attempt to fly! Have your radio equipment

checked out by the manufacturer.

Double-check that all controls (aileron, elevator, rudder

and throttle) move in the correct direction.

Check the radio installation and make sure all the

control surfaces are moving correctly (i.e., the correct

direction and with the recommended throws).

Check all the control horns, servo horns, and clevises

to make sure they are secure and in good condition.
