Retractable Tail Landing Gear set.

Wheel Diameter: 28mm

Base Plate Size: 25x49mm

This will raise the tail off the ground by around 75mm when

lowered and locked.

 The whole retract weights only 17gr, incl. wheel! Made of durable nylon plastic. Can be steered with 'pull-pull' cables when extended. I guess this retract could be used for any plane from 125 to 180cm (50" to 70") wingspan.
