friends i bought a electric retracting gear system from rcbazaar but in the product contains 3nos retracting system and also wires but i didn't received the control unit where to buy that ?


i bought a gear sequencer from ebay but that is much different than what i bought . in the retracting system contains only 2 wires but the sequencer out is 3 pin out this is used for servos only . where can i buy a suitable sequencer for this retracting system

Ask rcb for the control unit.

Sequencer you mentioned is for servo type retracts / retracts which work on servos , but the one you got from RCB is of DC motor  you can't control them using a servo output ! Try RCB for it's control unit / else search for DC retracts control

or use a brushed ESC to control retracts via rx

Yeah ! That's also an option ! Probably a reversible one ! But the later option will be more comfortable
