Pro 4 weak diffs?
I've heard rumors the Pro 4 has weak diffs. Has anyone had a problem with this? I'm thinking of updating my touring car. But I have enough "fun" dealing with my Savage and its break-o-matic diffs. I don't need a tourer with the same problem.

RE: Pro 4 weak diffs?
In the beginning when the kit first came out the pro 4 had a problem with the diffs. HPI addressed this problem and made beefier diff gears for the pro4 (ver. 1.1 I think they are called). If you buy a kit that still has the old gears, I believe you can contact HPI and they will send you the new ones. If nothing else make sure that the gears are shimmed properly.

RE: Pro 4 weak diffs?
thanks for the info. I've been reading that the pro-4 is a very fast/quick turning car. I guess I'll find out after christmas. Looks like my tc3 is gonna get a hv5800 B/L and a rally conversion.
