That 1512/1.5d is going to be one beast of a motor in a crt.5 Its a beast in a 1/8 buggy on 4s. Edumakated had his 1/8 buggy up to almost 70 mph on the 1512/1.5D and 4s.
You might want to make sure you have planty of tires on hand when you run it. I suspect you will be blowing them off the rims with very little effort.
I can't decide if its more fun
to make it...
or break it...
