Paul, if you saw the vid of Joe's plane I have no doubt the G loads in the upper and lower corners where the looping was tightest was even higher than 20 G's.

For myself I'd have no problem being there but I'd be sure to place myself in a spot outside of any likely trajectories fer sure! ! ! !

But NOTHING matches being near a control line Jet speed model or a trio of K&B 40 powered Fast Rat Racers for shear fear factor. It was always in the forefront of my mind that a broken set of lines on these would mean instant perforation for anything or anyone that was in the path. I never did stand within 3 circle diameters of any jet speed model without being behind something like a car.
