I agree that the 1520 on 9s or 10s may be too much. I guess what I'm saying is that I'd go with the biggest motor that can fit (since this is a big truck that needs a large motor) and then choose the appropriate voltage and gearing. Rather than deciding on a voltage first (9s-12s), all of the factors (kv, voltage, gearing) need to be considered. So I might go with the 1520 on, say, 6s-8s over the 4082 on higher voltages.

I think the leopard 4082 1000kv on 10s and the 1520 on 6s would be comparable power output.

Now the leopard 1250kv 4082 on 10s might have an edge over the 1520 on 8s. Not sure, probably be close.

Given his setup i would go with a 1717 motor on 7-8s. The power output of a 1717 is somewhere between a 1521 and 1527 neu. The 1527 would still be the best fit, and would allow for lower motor speed and a larger pinion to help with gear wear and overall durability.

A good setup would be the leopard 5682 910 kv motor. Large diameter so lots of torques and 33k rpm on 10s. Slightly shorter than the 92 motor so not as huge power output. Might be able to get the motor far enough from the spur as larger pinions would be used to make up for the slower motor speed...
