Ive put a set on my sons, and it is alot better. Turns better and handles the jumps better. Mine is set up with the Cav's set up and doesn't turn as well or jumps as well. That said, we both drove a RB5 tonight, man their car handles so much better. Instantly gained 1/2 a second a lap. With this being our first time to drive a Kyosho. Sad to say, probably going to change cars after driving an Associated for 30+yrs. Cav must be one hell of a driver to beat superior cars.
