I have a feeling the motor may not like that... My money is on the lipo doing ok, but I would prefer to see a little more capacity.

I run a 833kv outrunner that is about twice as powerful in my 10th comp crawler. It is geared for about 8mph. I run 1800-2100mah 25c 3s lipos. I have gone up to a 2200 30c neu recently, and I notice the difference. This is the same outrunner that did 50mph on 4s in my direct to diff redcat project (long time ago...). I have some experience with those crawlmasters, and had better luck with a axi 2217 (tiny motor). Just my experience here, but I would go with a higher kv inreunner and gear it lower. Something like 2500kv s can style motor.
