I appreciate your concern and it does not fall on deaf ears, but......
What if it works??? I have been thinking about this for some time and now I just need to know. Failure (without injury) is an acceptable outcome but that would probably lead to a redesign rather than calling it quits. I have been thinking about the tendency to lean left although I am not sure if it will lean left or right as my prop is pushing rather than pulling. My plan is to hit the throttle VERY slowly once rolling. I will definitely have a helmet and a video camera on.
