Very interesting... I'm going to stay tuned to see what the AMA says. Personally, I think that this event has the potential to be safer than a jet speed event. Yes, I know that kinetic enegry is determined by both mass
and speed and a big, slow model can be as destructive as a small, fast one. However, I think that the techniques for building very big models as opposed to very fast ones are simpler and better known to most experienced modelers, the strength needed for a heavy weight is more easily tested than that required for very fast speed, and a big, slow model is easier to get out of the way of if it starts to go astray...
