OQ-2A Wimpy
Sketch shows how the landing gear flexes (above left). The spring is from an old retract type ball point pen. The shock absorbing landing gear is helpful when using the parachute recovery option of the OQ-2A. Assembled framework

The drawings show only the main and rear bottom spars extending into the fuselage, to provide the proper dihedral angle and to
simulate the pinned joint of the real air- plane. The wing must be supported by a strut to make it strong enough for the rig- ors of flying and landing per the actual drone. To build up the wing panels install the spars into the jigs shown, then glue the ribs
