While testing one of my new hot brushless motors I had just mounted in a 3D type plane I somehow energized it by accident and the 11X8 prop cut my left forefinger tip to the bone twice!!
EIGHT STITCHES and I am LEFT HANDED of course.
If that wasn't bad enough how about the fact I badly damaged 5 airplanes and burnt up a brushless speed controler complete with a new motor in the process?
The plane that cut me took off at full throttle across the shop hitting 3 other planes hanging from the ceiling. Next it proceeded to dive right into my main workbench where it tore up another plane I had just finished covering. After spending some time doing these things it then found my little rack that I keep all of my various bottles of CA in and promptly spread thick and thin CA all over my best tools. Finally stopping wedged in a corner where the prop could no longer spin. This smoked the controller and the motor and almost melted the batteries.
BTW: I usually follow a strict set of safety guidelines I adopted years ago when operating on or working on electrics. I left out one simple step and look what happened!!
I always have a fuse in-line and never energize the motor without it being mounted either in a test stand or in an airplane. Then I only apply power if the plane is going to takeoff or it's in a test stand. While building this one I ran out of fuses and used a short piece of jumper wire in place of the fuse. STUPID IDEA!!
I forgot to remove it as I went to adjust the control surfaces.
Somehow the motor went to WFO when I switched on the receiver. (the transmitter was on)
Live and learn!! OUCH!!

I had my E3D do the same thing when I turned it on the other day to do some taxi tests in the parking lot behind my dorm. It went to full luckily a parked car stopped it. 
I broke the nose off, but its back together now. I was going to test fly it today, but the winds are blowing way too much.
Sorry to hear about you burning up the controller. I know those things can get pretty expensive. If its a Jeti you can send it to Hobby Lobby and I think they'll replace it for half the cost of a new one. (or repair it)

Sorry to hear about the carnage. I did the same thing with a 20 size trainer. Used an electric starter to get it going and when I put the starter off to the side the starter wire pulled the throttle to wide open. Plane jumped forward and hit me in the right hand. 9 stitches on my middle finger. Never put the transmitter on the same side of the plane as the starter anymore.
