12:1 FDR? that does sound rather high for a large MT type vehicle- and only 28,000rpms on 12cells. Im no expert, but that sound like an under powered & overgeared setup... I could be wrong though.

I would suggest going with higher voltage or slightly higher kv motor to get rpms in the 35k range. Then you'll see you won't need such high gearing.

With the Revo that Lincpimp has now, I ran a 7XL on 5s2p A123 with 20/46 pinion/spur. It had plenty of power, and 40mph top speed was enough for me. The 7XL ran at a good temp, but as Lincpimp noted, the MM runs hot.

Yeah, I found that the 7XL has loads (s**t loads) of power on 5s2p, but it also takes s**t loads (huge s**t loads) of power from the battery. Drawing 135amps consistently.

I too have the TrueRC 4K cells, but in an 8K pack. I think 4K is too small. I think the motor you are looking at is a bit small too. A 1940 at a min. A 1940/7 on 4S would be great. The MM may or may not like 5S, I wouldn't bank the setup on it.

You should be getting ~120A peaks, which is alot for a 40A continuous cell. Driving is very peaky, and I think you will overdraw and heat up the cells. If you really want low weight you got to pony up a bit. I'd at least get the 5K cells if you are determined to stay cheap and 1P
