You don’t have to be a master modeler to add the realism of functioning retracts to your airplane. The completely self-contained E-flite® retract system requires no air tank, complex linkages or extra servo. It can simply be bolted into place and plugged into the receiver. A specially-designed Y-harness is included that allows for the use of a single receiver channel to control all retract units.
