Very cool! Thanks. What I’m trying to do specifically is something that is easy for people to build and that stays under 250 grams.

Yeah, work in progress. I don’t want to send it through an AI for cleanup.

We tested your theory with version 2 (which we’ll put on thingiverse next week) and it turns out that it can do a horizontal takeoff on low battery when there’s not enough juice to do a vertical takeoff. We filmed it, too!

There are surely dozens of variations on this theme flying.

One problem with outrunner motors, they don’t freewheel well enough to operate in autogyro, unpowered mode while in forward flight.

Maneuverability is going to be less of a problem then terrible wind tolerance associated with low wing loading/speed.

https://www.youtube.com/watch?v=H-1vfaKUkVA We’ve done this, we’re just looking for a way to do it as cheaply and easily as possible. The idea is that it should be JUST barely unstable and let the quadcopter’s IMU do its thing, for maneuverability.

I have the same idea, vertical wing and after start to turn quadcopter with propellers forward and wing will be horizontal to create lift. Maybe the tail will be not needed.

Suggestions:
Symmetric vertical airfoil on a centerline, then lean it over 90 degrees for forward flight.
Gonna need a tail.
CG in front of CP.
CG about 15-20% of chord back from front of wing.

Go out on the RC groups, surely a half dozen plans available.

Getting it back into quad mode is the bitch, 500 ft altitude makes FAA sad.
You won’t like the FAA when they’re sad.
