How much can the BigMaxximums pull anyways? I was looking for 1/5 brushless info, and I came across a German site with 1/5 vehicles (FG, etc.), and they used BigMaxximum. Must be a really low kv or what? Cause I have not seen any 1/5 motors from Plettenberg, and BigMaxximum is supposed to be a 1/8 motor.
