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 that 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 that 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 that 

the switch harness moves freely in both directions.
