Grip roll!!!!
 

Im running a hyper star pro uk buggy and seem to be struggling unbelievably with grip roll but also I can't seem to get it to run smooth over bumps or cornering with speed such as losi and AE any help on setup to eliminate this would be greatly apreciated.

What track and what tyres are you using?

30w front 35w rear blue spibgs (soft) and cut the out side spikes of your tyres

Thanks I'll give that a try.
