Hey can those ball diffs change their own balls and sand down their own rings? Just because it's easier to adjust doesn't mean maintenance free. I do see the point you were making, ball diffs are still plenty competitive. I've actually used one instead of a spool up front last season to lessen the twist put on the front dcj's by a spool.

I recall many years ago seeing someone at my local track developed a way put a removable cap in a hole in the diff housing. He would use a syringe to extract and fill fluid in the diff without removing it from the bulkheads. Whether that situation was reliable or whether it leaked or not, I don't know. It seems simple enough to try. Any takers?

Gear diffs aren't maintenance free either. I've had plenty when I ran nitro. Just like the shocks, they need to be rebuilt from time to time when the fluid in them looses its effectiveness.

Nothing in rc is "maintenance free".....nothing.

While on the subject of diffs I've been able to convert all but one of my older cars to gear diffs these being the oldest two with them installed.

Maybe instead of trying to determine if a car is old or not, we can view from the perspective that the older, the better.
If your 2017 is still competitive, that's good.
If your 1999 is still whipping butt, we have a winner!

Had one of those. Nice car but the down side to it back then was weight. I'm sure with lipo and brushless, it would have more motivation than it did with nimh and brushed motors.

Anyone have one with brushless and lipo? BTW I have the Japanese version of that single belt concept. Kawada Sigma 2.



At this point, we're somewhat thread jacking because these cars are old but definitely NOT racing competitively.

My xxxs was brushless AND lipo previous to its retirement. It did however take 1st in its last race so i wouldn't say it was outclassed by the cars at that time. Even a new car needs a driver to be successful.
