Other than for parking lot bashing I don't really think you get the idea of a OS .18cvr in a 1/10th scale yet. It will be REALLY tough to control it when you hit gas.

I have a OFNA OB4 Pro w/a OS .18cvr and its well....fast! Why did I put it in there? Well, it goes fast, in a straight line.

No amount of upgrades will help you when that 1/10th scale on-road slams into a curb at 50mph+. Damage between 50 and 70mph is really negligible. Both hits destroy the car badly.

Get a GOOD body with high downforce and you'll be alot happier.
