awesome work

Is the tail motor tilt angle permanently adjusted at some inclination ?

Hi Stephen , 

that is a great step hybrid bt a plane and a copter will save lots of energy and time bt waypoints ..genial.

Really nice! Thought about something similar and now it's already reality!

As Fernando said, it will save a lot of energy while flying fast and long distances but lacks nothing of the quadcopter benefits. This concept has good prospects. Carry on!

Looks pretty cool Stephen.

Cool, I'm working on a VTOL concept too, but for fast speed.

What about put a pusher as rear rotor and make it tilt backward/down to get a trimotor ? :D I love the concept.

Excellent ! might want ti wrap the motor wires to the boom I like how it took off when you got to altitude !

Very interesting! How do you make the translation from flying wing to tricopter?

Can maybe someone convert apm 2.5 from arducopter to arduplane with only one switch?
