After accidently knocking the safety switch I was using and the throttle lever together causing the motor to start I decided I needed a more fool proof method. What I came up with and what I use on all my gliders is the use the S1 switch on my Taranis. In the logic screen I program a logic switch so that S1 has to be more than Zero to be turned on, then in the function screen using that logic switch, if it turned off then the throttle switch is overridden to -100. So before starting a flight the S1 switch is turn passed Zero and before collecting the model after landing the S1 switch is turn fully to the left (-100).
