Ultralight Amphibious Electric Fixed Bi-Wing VTOL
This highly unusual design allows for fixed wing vtol with no rotating structural elements.
Raise nose with VTOL lever, take off with 10-15% power, recenter VTOL lever or disengage (option 8). To land, 6-7% power with gyro on will hover fairly well. Good Luck! The real thing is amphibious, my model is not however. Check out their website for videos.

@forthelove pretty good so far! Showed everyone here at the Opener office :-) Matches I'd say pretty well using SimplePlanes as a sim.
New blackfly is here @motorfiets

@forthelove great!! Please tag me when you upload!
@motorfiets I have really improved the design to be more responsive for landing and also mimic a more true to life takeoff. I’ll post an updated version soon.
@forthelove is it possible to increase pitch up to vtol hover speed? The Blackfly makes a very quick pitch up when going into hover. Also, when descending in hover it's hard to "catch" the aircraft when trying to slow the decent.
@motorfiets make sure you disable group 8 when you want to fly like a plane. The is a gyro to help for hovering, but it makes flying horrrible.
Tough to fly! But the concept is all there!
