This timer drives a servo to operate a fuel cut-off or venturi air barrel to govern the run time of IC engines. In the case of RC equipped engines the air barrel can be smoothly and progressively closed to ensure a gentle transition into level flight, rather than suffering a stall if the engine is stopped abruptly whilst the model is in a climbing attitude.
After a further delay the timer drives a D/T servo to terminate the flight. The throw of the throttle servo is set by a single turn potentiometer and the engine run and D/T periods are set by a simple push button / LED interface.
Programming Features:-
- engine run duration:- adjustable 1 to 30 seconds, set in 1 second increments
- d/t duration:- adjustable 10 seconds to 5 minutes, set in 10 second increments
- throttle servo throw is fully adjustable by potentiometer
- engine run down:- adjustable 0 to 10 seconds
- push button immediately closes the throttle at any point during the flight profile
- operable from a single (3.7v) LiPo cell – max voltage 5.5v
- low voltage cut-out and visual indication of state of battery “health”
- duration settings are saved in memory – so a single button push serves to repeat a flight
- provision to fit remote pushbutton and remote LED
