tech notes on tower for the lrp 5.5 says its good for 3s just a heads up in case anyone was wondering. im the only one at our local races running 2s or a sc10 4xs4 and it sure seems that everyone is getting around a lot easier than i am it seems as though i have to push the truck really hard to keep up in sections where i have to be on and off the throttle alot. especially noticeable when i try the bigger jumps.
