50-60 runs, eh? And you want something longer lasting? You're funny....

50 runs before maintenance on a ball diff is pretty darn awesome.

Thanks for the tip, I will give this a shot. When you say glue, do you mean like plastic cement (for plastic models) or superglue?

From family I got some cool gifts, but they are non-RC related. They want to pull me out of the basement I guess. This entire week I spent most of the day working on my RC cars with my kids, will do the same entire next week since I'm off for 2 full weeks this holiday.

Hope you all have a great holiday.
I bought my RC collection a new house.

While moving, I came to the realization that I have an insane amount of RC cars and related gear... Some, like my wife for example, would say I have a problem. Good thing the new house is twice the size of the old one - more room for more stuff!

Uhhhh, I'm only running a 21.5T, not a serious mod motor...
Yes, ball diff should last A LOT longer.

Kinda like the pants solution. Rather than try hard to diet and exercise in order to fit into those old pants, just buy new pants with a larger waist.

You're just realizing this?! I've been hearing the legend of Scott's hobby room for years now, from anyone who's visited. I really need to make the pilgrimage some time. On a related note, if you decide to downsize someday, I want to be first in line!

I run a 21.5t and pretty much tear down my car to get to the diff which I inspect, re-tighten, etc... 2x a race season -thats about 1x every 5 race days (15 runs before I tear down). I usually break the car down and re-assemble bringing everything back to spec' mid season and again at the end of the season (So it's ready for the following season).

Hi eR1c - You guys drive your RC cars very little like I drive my real hobby cars.

Joke aside, the MantaRay diff at it's factory assembled setting is not all that stiff so I think my situation is a little different. I use threadlock, etc and the diff screw itself is not loosening. It's the bellwashers that are actually wearing out. So no further screw tightening fixes this, I need to replace the parts.

My other ball diffs on other chassis do not loosen much, if at all. And 99% of the time, it's just re-tightening the screw/nut holding the assembly together as you said.

I much prefer the oil gear diffs, but since none is specifically available for the M03, I decided to do the MR diff instead. I have more diff shims coming to me. Will fill with 80K+ oil too and seal it up.

I got some of the 3mm plugs to convert a ball diff into a slipper spool. They work well, only slipping when really pushed hard. The only caveat is that when being installed in a ta03 diff, you'll have to drill the holes out to 3mm, so the plugs go all the way through. I think a different model of ball diff might be better for this purpose, as they tend to be simpler and lighter. Less rotating mass is good.

Would re-building the manta ray diff without the balls, achieve the same thing?

Manta Ray diff and TA03 diff are essentially the same item. I suppose it could. Maybe some home made slipper pads?
