The B74.1 will be a much better car for the offroad track. I love mine. Racing it on mostly carpet so I changed lots of things setup wise. But I do switch between blue groove clay (The Track in Gburg) and Hard Pack clay (Beach RC for vaca - Myrtle Beach) so I got some stuff for that. One thing to note, still learning more about the car, how I can make it better, drive better and everything. This was my first kit and first 4wd car so it was a bit getting used too. Now I am struggling a bit switching from 4wd 1/10 to 2wd 1/16 if racing the B74 and Mini B on the same night. Lol. Back earlier this year, my driving was poor, and I broke some stuff. Now since I now the car, traction, track, and I drive more better, I haven't broken anything on the car since April so that is super amazing for me. Huge step up from the Mini B (which I do for fun, not competitive) and Traxxas 2wd bashers (which I was trying to get them tuned up for the tracks, too much time and money, leaving them as bashers, might sell them so I got some money, and maybe another race kit in the future, or better basher)
The RB10 might be a ok car for oval? Compare the RB10 to the SR10? Setup wise, parts wise?
