That's really cool.
I'm arm-deep in electronics, servos and motor controllers for the robot project now. I'm having fun, learning a lot...even tho those buggers aint cheap.
I got some photos from the gent who now owns my BD-5. Its doing taxi-tests for its first flight...he installed a jet engine in it and during run-up tests, cooked a nice hole in the asphalt LOL. But its all signed off and ready to go.
