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.

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. Be sure 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 at this time.
 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.
