RE: side in tips
The "turning body" thing reminded me of learning to fly RC gliders in the 80's. There was a field instructor there who would whack us with an TX antenna if we did that. I guess he was hard and fast against that rule. It actually got pretty bad.... there were folks doing tail-out landings (RC gliders) who would actually turn their back to the model, and steer it in for a landing looking over their shoulder. It sounds silly, but it's true. It was entertaining to watch those glider folks do their over the shoulder landings. Neall
