Hpi hellfire ss

Thanks for the replies

Patrick I think what I should be aiming for is a rig that can do speed runs of 60 to 70 mph on 6s with optimal gearing and also be able to dial it down to give 35 to 40mph. From my experience with the kyosha tyre ballooning on a 4 wheel drive is more problamatic than on a 2 wheel drive, I found either more ballooning on the rear than on the front or vise versa and battled to get a even balance I eventualy ended up locking both diffs. Do you think I will have the same problem with the hellfire? The hellfire bieng heavier does this mean a bigger motor or just beef up the suspension.

Thanks for the help
