Just installed the Scorpion and the 6.8 in my RC18T. Runs very smooth and quiet. I've been running with the stock connectors and the 6-cell 1100 MAh NiMH that came in the Associated RTR package. I've been told this pack is very similar to the GP 1100 6-cell. No cogging whatesoever, and definitely too fast to drive around in the office!
Awesome and dropped right in the chassis perfectly
