I can relate. When I was about 24 (I'm 37 now) just getting into R/C, I did one of these.
Get this though. I REACHED THROUGH THE PROP TO REMOVE THE GLOW STARTER !! :stupid:
Required a guy to stop the engine, another to hold my thumb and forefinger together, another to drive me to the hospital.
Since then I have gained the respect of anything that turns knives around at high RPM. I even think twice about how I am about to use my circular and band saws.
Don't feel too bad. There are others out there that have brain fade too.
