As Brett has pointed out many times though, once the system is built there is no practical way to prove that it isn't acting as an autopilot of sorts to smooth out maneuvers, minimize over control, control the engine run which is already allowed in electric(very bad decision that ).
I agree on the autopilot, but not the engine/motor. I see nothing being done in electric that couldn't have been and has been done on engines, and the reliability is (somewhat to my surprise) similar. Igor's feedback system effectively accomplishes the same thing, more-or-less, that Aldrich was trying to do with a Fox 35, Big Jim was trying to do with the ST60, and Hunt/Pappas did with the tuned pipe. In fact, even after thinking about how to improve on it on IC engines using electronic feedback control for something like 45 years, I still can't see a way to do better than I am doing with a pipe and an Eather prop.
I still routinely see the same sorts of problems with electric setup that I see all the time with IC setup, for many of the same reasons. Many people set their controller up with FAR more response that they should, because it makes the feel like heroes when it pulls their arms off in the corners. Unfortunately, it also makes the airplane much harder to fly than it would be otherwise.
Every successful stunt power system since about 1950 has had very similar characteristics, I am not at all hung up on finding another way to do the same thing.
