Wich NIMH battery for brushless setup?

Thanks guys.

@ Sylvester,

the A class motor is working really good for me. In my buggy I got 40/45mph and 30 minutes runtime with crappy GP3300 cells. These cells are dead now. Because I ran the buggy with fresh batterys, wich were 40 C and the outside temperature was 30 C. So after a few lines running, the batts began to smoke. They are toasted. The motor is running really smoothly. The flat grinded spot on the shaft is also really helpfull to attach the pinions. And the big heatsink provides a good transformation for heat. The runtimes are really amazing with this motor. I am really curious on how the motor perfomances with new cells!
