Use of failsafe on R/C systems.
You need to be aware that it is mandatory to set the failsafe if it is fitted to your radio system, That means all 2.4Ghz radios and any 35Mhz systems using a PCM Rx. The minimum setting required is that the control surfaces hold their last position and the throttle is closed to at least idle. Those of you preparing to take the ‘A’ achievement test will be asked to demonstrate the operation of the failsafe as part of your pre-flight checks. Further to that you should test your failsafe on a regular basis and certainly following any program changes to your models. To demonstrate the operation of the failsafe the model must be restrained, the motor/engine RPM set above idle (but not necessarily full throttle) then the TX is turned off, at which point the motor/engine should go to idle.
