That motor is too much in a 1/8 buggy. So I can't see how you are going to get your CRT's full potential. I think you would be better off with a 1509. Maybe run the 3300kv 1509 or the 4500kv one. You will get longer run times too.
One of these days I was going to do a crt .5 or the hyper version with the 1509. I want it to hit about 75-80 mph.
