It's not the speed that will kill, it's the handling tendancies.

And edge is going to be very responsive, and do exactly what you tell it to do. The problem is that inexperienced pilots aren't used to that. Trainers have a lot of stability in them, the Edge is totally neutral (or close). Trainers are designed to make it hard to stall and spin them in to the ground. The Edge is built to stall and spin easily on command.

I've seen guys take planes up they weren't ready for. What almost always happens is that they get it off the ground, and then they either loose it in the first turn as they over control and end up low and inverted or snaproll in to the ground, or they survive the first turn and fly it around a bit in a crazy, half-controlled way. Sometimes they plant it during this stage, but most go high enough to avoid that part. Then comes landing. And you can pretty much see it coming. They get the approach wrong, and either over control it or, more commonly, they stall and fall off and in to the ground. It usually happens on the turn from downwind to base or to final. Most guys shoot a continuious 180 degree turn, and it's during this turn that things almost always go south. About half the time it's accomponied by cries of "I don't have it" or "I've been hit", with lots of blame placed on a radio that is working just fine.

A couple of months ago, I got to see two planes go in, almost exactly like this, one right after the other. It was amazing. and sad. Totally preventable.
