Anyone Running a Gear Diff on Indoor Clay? 2WD Buggy.
While my young boys are learning to drive r/c, I put the gear diff that came with my centro c4.2 (used) in and I actually think the car feels very good, especially when the track is hooking up nicely.
Anyone else out there using a gear diff on indoor clay in their 2WD buggies? thanks. |
I do actually on my Dex210 V2 i use 3k in my tried 4k but that took out the mid corner steering and rotation positive with 4k on clay is it didn't diff out quite as much .
So as long as its medium to higher grip in the day it works fine on clay from running a ball diff honesty im not any faster with ethier one just less of a pain with a gear diff. |
I also run a gear diff, also in a DEX210. I think I use 2k AE oil, but that's more because it's what I had lying around. I too use it because it's less maintenance than a ball diff and I can't say I notice a huge difference in performance.
Pretty sure a ball diff is lighter than a gear diff, so if you're chasing weight, it's one sacrifice to make. |
A lot of people do. Cavaleri won the ROAR Championship with a gear diff (He used 3k oil).
I've been interested in trying one. Like noted above though, it adds more weight, and it's rotating mass, so its a double whammy. |

One thing that i think lowers the weight of the gear diff is composite plastic spider gears which i have in my gear diff so that's got to reduce rotating mase. One thing i had to do running a gear diff compared to the ball diff was turn down the expo because it gave me a lot more power on the bottom . I run Mod Buggy . |
thanks for the replies. yeah, it's working well. We have ramps we setup in our front yard and the car gets driven at the track as well, so driven a lot... the gear diff is the ticket.

I haven't tried it on dirt but I have a gear diff for my B5M when I run carpet.
I forget how much bit it was lighter than the factory ball diff. I did only use 2 spider gears to get more fluid in the diff though... |

I have only personally ran ball diffs in my car. But i have made many laps with my brothers very similar set up with gear diffs. I couldnt tell any difference in how they worked. And his" build it and forget it" almost has me 100% sold on them. No of i can convert something to fit my buggy i will run one for sure.

A little off topic. What are you guys using to seal up your gear diffs. Anytime I have used one I end up with a tranny full of diff lube. I just use the stock gaskets.
|
From running the gear diff on the 2wd for a while i noticed on medium traction on the clay is. That 4K diff oil works better than 3k less wheel spin kind of like a tighter ball diff with less diffing out .
Downside is you lose some mid cornering steering and rotation but you tune other things . |

I use just RV seal blue colored replace the gaskets and o -rings if it still leaks there might be a crack somewhere on the case . |
There are a couple guys at my indoor clay track (high bite) running gear diffs in their B5ms with great success. I personally like to be able to tighten or loosen my diff on the fly. I usually make at least one adjustment on any given race day. Rebuilding a gear diff to be a bit looser or tighter every time a change in the track would dictate, would be a major pain for me.

Yea I wouldn't do it at the track with the gear diff that's a do at home thing but if it doesn't work there is other adjustments on the car . |
