Servoless Electric Retract Landing Gear Housing (3500G)

A housing designed for a 3500G servoless electric retractable landing gear unit (40 g). It holds the retract, leaves an open channel for the leg to swing into, and mounts into the airframe through a flat top flange with four M2 screws.

What is in the project file

The 3MF is a Bambu Studio project with one plate and a single part: the retract housing, ready to slice. Tree supports (auto) are enabled in the project for the screw and pivot bosses under the flange.

Installation

Place the retract unit in the housing so the leg pivots between the two pivot bosses and folds into the open channel. Fit the housing into a matching cut-out in the wing or fuselage and fix it through the four Ø2 mm holes in the top flange with M2 screws (self-tapping screws work well in PETG). Check that the leg extends and retracts freely before closing up the airframe.
