Still not satisfied. Repairs made....my fault....cheap hardware.
Airframe hit the ground from 15 feet....airframe was more rugged than I had expected. The combination adhesive with carbon fiber gusset plates was a good choice on my part. The battery/yaw control platform broke free. It still flew, but lost forward/aft control which I expected. Regarding planform morphing airframes, if there are not 2 points of connection with the weight equally distributed between both airframes, allowing both airframes to move within "one another" the lower airframe will act like a clock pendulum. I suppose my theory proved right. Scaling up to gas powered.
