Two of the blades rotate backwards - which has made motor tuning and
proprotor sourcing interesting - so it should have almost no
gyroscopic stability. (This also led to its first sorta-flight a few
months ago: we used right handed threads on the Jesus nuts for the
counter-rotating proprotors, and discovered first hand why it's called
the Jesus nut. The proprotor probably would have climbed a couple
hundred feet if it hadn't hit the next balcony up. No injuries, but
no video, either - darn.)
I'm just wondering if the electric motor system will react very
differently to control inputs than the rocket motor system will. I
suspect latency is the only real issue - gain issues can be dealt with
in software.
