• A trigger that starts a Timer and counts up as a percentage of the full stick range.  At full throttle it counts second for second; at half throttle every other second; at about 10% it counts one second of flight duration for every 13 seconds of throttle time.  Can be used as a rough/dirty gauge of remaining flight duration based on prior performance of the model & power set up.

A note of caution:  The initial duration that you would set for this TH% timer would be equivalent to how many minutes you would expect to run at wide open throttle, a considerably lower number than you probably use for other timers.
