Check Your Radio

Before going to the field, ensure your batteries are fully 

charged per your radio’s instructions. 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.
Prior to each flying session, make 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.

Range Test your Radio

Before each flying session, and especially with a new model, 

it is important to perform a range check. It is helpful to have 

another person available to assist during the range check. If 

you are using a Spektrum transmitter, please refer to your 

transmitter’s manual for detailed instructions on the range 

check process.

Safety Do’s and Don’ts for Pilots

•  Consult local laws and ordinances before choosing a 

location to fly your aircraft.

•   Check all control surfaces prior to each takeoff.
•   Do not fly your model near spectators, parking areas or 

any other area that could result in injury to people or 

damage of property.

•   Do not fly during adverse weather conditions. Poor 

visibility can cause disorientation and loss of control of 

your aircraft. Strong winds can cause similar problems.

•   Do not take chances. If at any time during flight 

you observe any erratic or abnormal operation, land 

immediately and do not resume flight until the cause of 

the problem has been ascertained and corrected. Safety 

can never be taken lightly.

•  Do not fly near power lines.

Daily Flight Checks

•   1. Check the battery voltage of the transmitter battery. 

Do not fly below the manufacturer’s recommended 

voltage. To do so can crash your aircraft.

When you check these batteries, ensure you have the 

polarities correct on your expanded scale voltmeter.

•   2. Check all hardware (linkages, screws, nuts, and bolts) 

prior to each day’s flight. Ensure that binding does not 

occur and that all parts are properly secured.

•   3. Ensure all surfaces are moving in the 

 

proper manner.

•   4. Perform a ground range check before each day’s 

flying session.

•   5. Prior to starting your aircraft, turn off your 

transmitter, then turn it back on. Do this each time you 

start your aircraft. If any critical switches are on without 

your knowledge, the transmitter alarm will sound a 

warning.

•  6. Check that all trim levers are in the proper location.
•   7. All servo pigtails and switch harness plugs should be 

secured in the receiver. Make sure the switch harness 

moves freely in both directions.
