The compact Gemini is a Chris Heintz (of Zenair Co., Canada) designed twin engined two seater with a wingspan only 3 in (76 mm) greater than that of the Zenith Zodiac, with which it shares many components.
Its square tipped low wings are built around a single spar and, like the rest of the Gemini, are stressed aluminium skinned.
Most of the taper is on the trailing edges, which carry mass balanced ailerons over almost all the span outboard of the engines.
The tailplane is rectangular in plan, the separate, mass balanced elevators having a cut-out for the movement of a tall, tapered, all-moving rudder.
The tailwheel is fixed but the mainwheels retract backwards into the engine nacelles, leaving the wheels slightly protruding in case of a wheels-up landing.
