The gear door does not work because it's a safety program which if you have one gear issue it automatically keeps the doors open. Once you plug in the three or nose retract with the two main retracts then the gear doors will work!
That controller is designed for three sets of retracts which prohibits the retract door servo from working as a safety mechanism since the third set is not plugged in. You would need a controller for two wheel setup.
i also have, this JP Hobby ER-120, and i am using this retracts with 3 wires which i bought in an online shops, how can modify this retracts from 3 wires to 2 wires that is (positive and negative wires only)?
