Gemini International, Gemini Humminbird Ultralight
It is a high wing, tractor configuration, using two Solo engines, one mounted on the leading edge of each wing. I have seen both direct drive and reduction drives on these aircraft. The craft is a tri-cycle gear, with a steerable nosewheel. Controls are via rudder pedals and an V tail with ruddervators.
The Hummingbird was powered by two 8 hp (6 kW) single-cylinder Husqvarna AB Partner chainsaw engines with reduction drives, two twin-cylinder direct drive Limbach Flugmotoren engines, as well as two Solo engines with redrives.
