Tailheavy,

yes, that is too much for that motor!!

You will have to replace the field in it or demag it one..

I tried a 3S2P w/ same motor and it is on it way back from the repair shop now!

You need a "L" can and a 18 wind for the 11" prop, or you can amp down to the 2S and maybe use that motor.. Be sure to check the amps, though..
