So I had this idea for a project that formed through thoughts and doodling as a result of '80s-era research by Sikorsky* to create a helicopter using an "X" wing that was able to change into a fixed wing aircraft and vice-versa. I sort of always considered making a fixed wing, .049 powered version for R/C. Not so interested in the heli format and it's associated complexities but wanted it to do more than just fly as a fixed-wing vehicle...

What I came up with was a means to fold the fuselage so that the center of gravity would be directly below the flying surface to allow for the transition into a vehicle capable of (hopefully) a soft, FF mode, auto-rotation - sort of like a maple seed. Used Fanfold foam left-overs to create a proof-of-concept glider that so far seems to show enough promise to hold my interest in pursuing it.
Hoping to use 6 channels (6 servos) to control roll, pitch, throttle (engine cut-off on demand), fuselage fold release, and flight control reconfiguration for auto-rotation sequence. (Now, as I write this, the statement alone is scaring me in reference to weight considerations...)
To be all balsa and ply construction with lots of design obstacles ahead but hoping to work through them as I go. Hoping this posting will be incentive enough to push forth.
Hence the name based on acronym: X-WRAE; X:(X) - W:(WING configuration) R:(RECOVERY by) A:(AUTO-ROTATION) E:(EXPERIMENTAL) to be pronounced - "X-Ray".
