What I don't like about the motor is that the mounting method really causes you to have to stretch to put the pinion in a place that would give good mesh with the spur, so the pinion is going to be riding pretty far out from the bearing. Ken told me that their reason for offering the long extended pinions was so that they could use their motor setup on an 8ight, which has the center diff mounted backwards (as compared to others).

As for the amp draw, the motor is a really low kv motor and the amp draw is probably right. Ken (at Mega) told me that they run these motors on 6S to 8S lipo, IIRC. At those voltages, the current draw should be low when geared for dirt track racing.

As for mounting the motor, I think that I'd have to do a bit of out of the box thinking with regard to mounting it. There has to be a way to get the motor closer to the spur.

I do, however, agree with Brian on the chassis flex issue. You really should stiffen the chassis somehow.
