In this video I cover the basics about the two styles of differentials. I also give an explanations as to why ball differential may be a better choice for loose bumpy surfaces, and gear differentials may be best for smooth high traction surfaces.

Funny how no manufacturers (even aftermarket) have made a clutched diff or work gear (torque sensing) diff like full scale vehicles have.

Good point. I would love to see a helical diff. Not sure if they would handle the stress at that scale. Maybe they just assume diff fluid is good enough.

Could you just use a light oil in the gear diff to act similar to the ball diff with a lot less maintenance? You'd just miss out on the ability to adjust tightness.

You can. Now, ball diffs are consistent from start to finish of the differential rotation. Fluid filled diffs will increase resistance as speed differential increases... but most of us could probably not tell the difference. So, yes... sealed fluid filled is far easier to upkeep. I actually swapped my diff. in my Xray X1 for this reason and never looked back.

Okay so if i understand this correctly. Empty full open gear diff will have same effect like ball diff it just will be tiny bit slower in reactions right? Without fluid it should have same properties as ball diff.

The way you can control the ball diff. by tightening it you can control an open diff. by using back, red, or naval grease. The delay will be different. I would not say the same due to how a gear diff. builds up resistance, but similar in a sense (the way I am interpreting your description).

@@telecomandorc hmmm. Thanks for explaining it to me. Im racing offroad RC cars over 10 years but i never really understood why anyone would want to use ball diff. Gear diff always felt same if not superior to it for me.

@@telecomandorc great video, very informative! Can I achieve a similar feel to that if the ball diff with a gear diff by using low viscosity oil/grease? 2k cst?

@@chuchugaming1752 Not sure which would be best. Probably the oil. Black grease gets tacky over time. It would be similar.
