How to fly RC Airplanes (4)—Pre-flight Checks 1

Fourth step: Pre-flight checks

The purpose of pre-flight checks is to ensure that your rc plane is in a fit condition to fly, and that everything is working as it should be. Exact pre-flight checks might differ from plane to plane, but there are some fundamental checks that all rc airplanes need to have done, immediately before flight.

If you neglect to carry out the pre-flight checks before you fly your rc airplane, and something is badly amiss, then an avoidable crash is very likely. Many rc pilots have lost their beloved aircraft seconds after take off, simply because they didn’t do the checks!  listed below (in no particular order) are the minimum checks that you need to carry out before you take off…

  • All servos are secure, and linkages to servo and control surfaces are secure.
  • Servo and control horns are secure and not loose.
  • Servo linkages are able to move freely and are not binding on anything.
  • All servo connections to the receiver, battery pack and ESC are secure and correct.
  • The receiver and motor battery pack are securely fixed and cannot move during flight.
  • Receiver antenna (aerial) is correctly positioned and not damaged.
  • The propeller nut is tight / spinner is secure.
  • The wing and tailplane (and fin) are secured properly, as per the instructions (i.e. with the correct method of fixing; rubber bands or wing nuts etc.)
  • All control surfaces move in the correct sense i.e. moving the rudder stick left moves the rudder to the left.
  • All control surface hinges are secure i.e. you can’t pull the control surface away from its respective flying surface.
  • The motor power works correctly, and stops when you want it to.
  • A range check
