Yeah really, I love ball diffs. Maybe it has something to do with being old. But race cars came with ball diffs and "toy RC cars" had gear diffs.

I also hate ball diffs in a wheeler. #1 reason I sold my 44.2. Not going to agree with the above comment but we are all entitled to one. With the power new brushless motors put out diffs don't stand a chance, not long anyway. Rebuildin very often to get the right feel is needed when running mod motors. Gear diffs IMO is far from toy rc's.

i would agree that if mod wheeler were the only option we are talking about, gear diffs all the way. with the popularity of the 13.5 wheeler class, i'd run ball diffs over gear diffs in all but the very highest traction conditions (carpet).

You obviously were not around for the RC10 days. That is how it was back then. Ball diffs were in all the race cars. Tamiyas and Nikkos had gear diffs. Obviously not the fluid filled diffs we have today.

Not that there is anything wrong with gear diffs. I just dont like them because they are "new" to me. I have had a set of B-Fast diffs in my B44.1 for about a year or so. 8.5, no rebuilds. Still smooth as glass. It was the plastic gears that made me put that car away.

Gear diffs have their place in RC for sure, both in racing and bashing. But so do ball diffs. Like Phreak said, for 13.5 I would want ball diffs with a slipper. I think that if people knew how to build a better ball diff themselves they would like them better in certain conditions.

Maybe you should put a request in to MIP for drop in BALL DIFFS for the non mod racer, could be a huge seller like PUCKS!

Maybe Schelle can make this as they make the Pro built ball diffs for the B5/B6 series.

Brushless isn't any harder on diffs than brushed motors were. Ever since 2000mah cells started being used in modified, the limit to how much power we run has been traction, not motors or batteries. Aside from the growth of carpet racing, power and traction haven't changed for 15 or more years.

A properly built ball diff with a properly set slipper protecting it lasts a very long time. It has the advantage that its action doesn't change under load. This is why they're still the best on 2wd buggies on dirt.

We will have to agree to disagree on your first paragraph. My 2 wheel at the 2002 mod nats was fast but not as fast as my car is today. It wheelied but only because the motor was hangin off the back.

You second paragraph is spot on though. For some reason I prefer gear diffs in 4wd vehicles. Gets the power to the ground better imo

He didn't 'make' a diff. He just builds them properly from AE / Schelle parts.

A lot of things were different back then, lighter weight motors and much heavier batteries resulted in a weight distribution that probably isn't as different as RM and MM configurations seem.

That aside, the limits of usable power were as easy to exceed in the brushed days as they are now, and ball diffs dealt with it very well and they continue to be the best for 2wd in dirt.

I certainly see the benefits of gear diff tuneability and perhaps the quality & precision of them is catching up enough that we'll see them take over for 2wd cars in the future as well. As this new dirt-focused release shows, they're here to stay in 4wd.
