it does have 12mm hubs
basicly the same chassis as the touring cars
Body will break/crack looking at it. Forget the stock body.
Spur gear is really it's only other weak point, larger tires can only make that worse. It can take some abuse, I had the short course version and it was a blast. Get your gearing and mesh correct first time and you should be fine. To loose and it will take the teeth right off that plastic metric spur. Luckily it is a cheap part
I jumped the sc version 8 feet high over and over again all day at the park here. Never broke down, the stock body wasn't on though I had a proline on.
