In what sense?
I have two of them, one with the gear diff, The other with ball diff and both feel really smooth to me, and the shocks in particular are Easier to set up and Adjust than the bladder shocks, although I am aware of the B3 comes with the bleeder carro although I am aware of the v3 comes with the bleeder caps. Just wish they were aluminum.
The main reason I moved away from Hobby pro is the way they dropped the ball on the SB 401, in particular the slipper. Will probably snatch up the K2 and if I like it better the SP is going up for sale.
The PRS1 is a fantastic buggy but the inner tie rod mounts on the transmission case needs to be done away with because that is the car's only true weak point.
Mine isn't going anywhere anytime soon, unless my YZ's prove considerably better.
