I run mainly AE stuff so I am kinda partial to a somewhat aggressive car...one that doesn't push to much. I was also hoping for a car that wouldn't be too set up intensive, ie;set and forget. I've only ran the S3 with the box chassis and SP2 is almost new. I might stick with the Kyosho since I have it and see how that goes. I haven't tried the TTR with the flat chassis, but thats an option too. Just thought about maybe trying something new...I used to run a Kanai 2/3. One of the things that was kinda swaying me away from Kyosho is the problems people are seeming to have with the ST-R with the pinions and front bones popping out (course I hear the SP2 pops rear bones out) since I was considering getting a truggy too one day. I was hoping to run same brand vehicles. Anyway, thanks for the suggestion, let me know any others you guys have.
