I agree with Tex....its mostly the driver
When it comes to Revo's racing against truggies, each one has their week points as well as their strong points.
I know for a fact that Ryan's Revo is just as fast, if not faster then my LSP on the straight. He can also hold much better lines when going around turns.
Most Revo's Ive seen, go where your want them too and actually hold the turns much better, at least much better then my understeering LSP, I have to use the rear brakes to get the rear to come around most of the time, just so I can turn tighter.

I raced out at AJ's yesterday, and Kevin's LST was only 10 sec behind my TQ spot. That track was sooo slippery loose dirt/sand mix and wide open throttle running with only 4 small jumps on the whole track....it was like running on a baseball diamond with speed bumps for jumps.....Truggies had no advantage their but yet I still heard people complain.

Anyway.....Ive heard these kind of complaints alot lately from non truggie owners when they loose, but I still think its mostly the driver

Give me 15min with a powerfull, hooked up Revo... and I bet I could have still won the races Ive won
