Jet Tronics door sequencer

Your model has a complicated (landing gear) flap control. Before the start, the model is on the runway, the landing gear is extended, but the landing gear doors are closed. After take-off, the following should now take place:

– Flaps open, landing gear retract, flaps closed.
– When landing, everything must be exactly the opposite:
– flaps open, undercarriage extended, flaps closed.

Such sequences are no problem for this sequencer!
This door sequencer is a further development of a flap control that has been in use for 10 years. It has the following properties:

– 3 flap outputs, 1 landing gear output
– 3 operating modes for all possible applications
– End position, direction and times of all servos programmable
– Off switch reminder
– no programming device required

– Easy programming with the help of a rotary encoder and a coding switch.
– Adjustable switching point, allowing multiple uses on one channel.

– Three operating modes:
Mode 1: flaps open, landing gear extend, flaps closed. Open the flaps, retract the landing gear, close the flaps.
Mode 2: Flaps open, landing gear extend, flap stays open. Open the flaps, retract the landing gear, close the flap.
Mode 3: Main landing gear doors open, landing gear extend, doors close. Nose landing gear flap open, landing gear extend, flap stays open.
