ok, back from all the calculators i know!

thanks suicideneil for the input
cause of that i begin to reflect


as 2nd gear setup

1. i hope to get a max. Current draw about 60amps
2. 22,2V max. battery voltage
3. Motor rpm about 35000 1/min
4. E-Maxx 2nd gear
5. Revo 40T
6. 13T pinion

ESC
TMM 12025-3 Car / Boat Z-SERIES with external heatsinks CUBE
or for a safetyreserve in voltage
TMM 14035-3 Car / Boat Z-SERIES with external heatsinks CUBE

Motor
LMH 1950/8 (1568kv) Hi-Amp with fan incl.



another alternative

the x2crt center will fit in my chassis with a slightly mod and there's enough room for a brakeservo


for a centerdiff or slipperential setup

1. i hope a max. Current draw about 40amps
2. 22,2V max. battery voltage
3. Motor rpm about 25000 1/min
4. X2 CRT centerdiff 48T
5. 13T pinion


ESC
TMM 12025-3 Car / Boat Z-SERIES with external heatsinks CUBE
or for a safetyreserve in voltage
TMM 14035-3 Car / Boat Z-SERIES with external heatsinks CUBE

Motor
LMH 1950/11 (1140kv) Hi-Amp with fan incl.

the other way for the esc is, give the rzrun150A a try?
