If you can't run a larger diameter motor (like the 5682) then I think your best bet is the 1527 if it will fit.

9s on the 1520 may be spiining that motor past its efficiency window, so it may get hotter than the 4082 on 10s running at a lower rpm.
Since he has the 1520 and lipos are now pretty cheap (compared to a few years ago) I think he can try the 1520 and see how it does.
He can pick up 2 5s packs and a 4s for testing. If he stays with 9s he can just buy another 4s pack and have 2 sets of batts for the truck, or sell the 4s off and get some money back if he sticks with 10s and another motor.
I do agree that the 1527 would be best. However that motor will cost more than the leopard and all of the lipos combined.
