My problem running 4WD is that the car (XXX4 G+) can't hold up for 5 minutes. Ballcups pop off and the CVD pins fall out. I've got everything completely correct built. Running a Vantage Surikarn 12x2, only this seems really hard on the drivetrain. Running a 6x1 would be insane!
Starting up a Spec class would be perfect IMO, enough power but not too much. Stock is too slow in 4WD.
The only problem here in Norway is that we really don't have enough racers to divide the Mod 4WD class that most of us run in.
Our last nationals had only 15 in 4WD and a couple more in 2WD. The total number of people RACING 1/10 buggies here is probably only the double, almost all the beginners go to 1/8 OR.
