E-flite Leader 480 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 makes the airplane 

elevator move up.

  3. Check the movement of the ailerons with the 

radio system. Moving the aileron stick right makes 

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.

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. Always install the control 

horns 90-degrees to the servo centerline. Use 

sub-trim as a last resort to center the servos.

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.

preflight

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.
