Sorry to hear what you had to go through. Coolbean is right, People tend to treat electrics as if they are not dangerous. Not only will the motor start with only 1 mistake (moving the trottle as opposed to the mutiple mistakes required to accidently start a glow engine) but the Electric Motor keeps turning regardless of what the prop is doing. The glow engine will quit while the electric motor keeps trying to move that prop, making a bad situation worse.

I used to fly the bigs ones for a living. You learn quick that you don't just read the steps and you never assume anything. Concentrate and Focus on every step before you move to the next one. Verify everything. On the flight deck I was trained to look and touch every knob and switch before moving to the next one. I still do that today out of habit even at the RC field.

Here's to wishing you a speedy recovery. And of course get back on the horse as quick as you can, the longer you wait the harder it will be to do.
