I LOVE mine. I bought the RTR model a while back and all I did was bought some ProLine Caliber M3 tires and some stock SC8 Wheels...... It is VERY track worthy now. Its a blast at the track and really likes to be slid sideways a lot.
I even had a buggy guy say to me "when you went by me i was like man, short course trucks aint supposed to pass 8th scale buggies!!"
Just go buy it. Its a blast and everyone that sees it wants one. I think its just price, timing, etc that made them not so popular.
