I measured the difference between the six cell GP3700 pack and the 8 cell GP2200 pack. The gp2200 pack is just about 5mm longer.

Wow, the 2240/12 is an awesome motor. I'd run lipos in that bad boy ;) Either way, that truck is going to be a beast.

I was looking at the lehner 2240/10 but my budget won't allow for that right now. Especially looking at the price of the skyvolts.

I'm not sure what kind of runtime you'll get with the 2200's but I get about 14.5 minute racing runtimes with my revo on 18 cells.
