These should be OK for F1Q. The inputs are wired so that latch is always open and hook forward becomes the start switch. One push activates the timer and subsequently holding the switch and releasing it starts the timer. Servo 1 would drive the stab as usual, probably using M&K fittings on the servo and at the rear while servo 2 would control the ESC which powers the timer via its BEC facility. An improvement on lockout after flying would be to put a second microswitch in series with the start switch and close it when the wing wiggler lever is set. This lever is released during normal flight events and, after the flight, the lever must be reset before the timer can be restarted.
