my bud is building a grass drag sled.
it is a 77 exciter or STX chassis, 44 mm flatslides and a 643 Yami motor out of an SR. he has the 643 SR pipes on it and asked me what the motor should top out at for RPM.
now, i know these motors were low revers but how high should be be reving this beast exactly for good power and durrability?
