New motor adivse

[lincpimp]

For a heavy truck like that a 1521 will be mandatory, or a 80mm medusa as a budget motor. 6s is a good idea, as is the 1500-1600kv range on the motor. I would not gear for much more than 40mph. And a flm al half case would be a good mod to go with that gmaxx single speed. Those motors are heavy, a thicker motor mount will be a good idea too. IIRC a finned neu with a 52t mod1 spur will allow a 16t pinion before you have contact with the tranny case.
