Designed for models with pneumatic (air) retract systems that utilize two air valves, one for the retracts and one for the gear doors, this circuit will allow you to sequence the action of the two (or more) valves for proper timing and operation. All the functions of this circuit can be adjusted to make it customizable for almost any model, including the direction (clockwise or counter-clockwise) of the rotation of the retract air valve, the delay between the cycle of the retract air valve and the cycle of the gear door air valve, and whether or not the gear doors remain open after the gear are down, or close back up until the command to raise the gear is received. The unit plugs into a single channel in your receiver, and connects to both the retract air valve and the gear door air valve. Can be used for multiple gear door air valves by using a common servo Y. Check the Product Details section for a description of a typical installation.
Small, compact, and easy to set up, this is a great way to solve the problem of gear door sequencing without having to use multiple channels in your receiver and/or complicated programming of your transmitter.
NOTE: This circuit is for use in retract systems utilizing two air valves, one for the pneumatic retracts, and one for the gear doors. If you need a Sequencer that is designed for systems that use only one air valve, and use a servo to move the gear doors, see the previous item in this collection.
