Adjust the stab until the measurements are equal. Now you can tighten the 3mm locknuts at the stabilizer. Range Testing the Radio 1. Before each flying session, be sure to range check your radio. This is accomplished by turning on your transmitter with the antenna collapsed. Turn on the receiver in your airplane.
Control Throws 1. Turn on the transmitter and receiver of your Mini Ultra Stick. Check the movement of the rudder, elevator and ailerons using the transmitter. Reverse the direction of the servos at the transmitter if necessary. 2. 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 widest point on the surface.
Preflight Check Your Radio Before going to the field, be sure that your batteries are fully charged, per the instructions included with your radio. Charge both the transmitter and receiver pack 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.
