My issue with the trainers that I have was the ground clearance...That is why I used my 1/4 Scale plane. I was also thinking that if you could mount the guy up on top of the wing using the rubber bands that the wing uses to hold the drop box. and then the pilot rolls inverted when it is time to drop and then Super Dave (that is my guys name after he burned in on our first drop
) will be on his way, then the trainer rolls right side up and then lands for another load.
