This is the E-Flite 10 to 15 - Size Tricycle Electric Retracts. Adding Retracts Has Never Been Easier.
Features
OverviewYou don’t have to be a master modeler to add the realism of functioning retracts to your airplane. E-flite’s completely self-contained retract system doesn’t require an air tank, complex linkages or even an extra servo. You simply bolt it into place and plug it into the receiver. A specially designed Y-harness is included that lets you use a single receiver channel to control all retract units.
