Oil filled gear diff gives you the best of both worlds: tunabilty and reliability.
Looks like Tamiya has finally taken the last step into cheap bastard land: the Alpine shell I just picked up doesn't come with window masks, but I do have a piece of paper with pictures of window masks. Yippee!

On a MO5 the front fit the Rides and rear the Cross tyres. On the MO6 you run the ride up front and cross rear.
Here in Sydney we are using betwwen 200 000wt and 500 000wt oil in our 3Racing gear diffs. These give the same performance as a tightened TAO3 ball diff.
The lighter oil will give more diffing out when attempting to accelerate out of a corner. We have found that the heavier oil is better.
Just an opinion. I can not comment on the MO6 as I still have a MO5 ball diff in mine, as I can only run it at club events and no one else down here runs them.
Availability of Rides and Cross tyres in the USA, no idea as I am located in Australia. You can purchase these from RC Mart.
On the MO5 if you use the light oil you will lack drive, unless you like having a really loose diff. It does not work with the Hobbywing BL systems we use. The oil supplied in our 3Racing MO6 oil gear diffs is only 700 wt, which no one uses.
Background,
I have run a modified SAK65 oil gear diff in my MO5 for a month, before the glue retaining the TAO3 gear to the 3Racing case and in that time I ran the car in club meets and a round of club challenge, where I made the A final. I finished down the order, however a couple of other cars had the same diff. I also used the ABR mini oil gear diff for about a month and that was good enough for me to qualify second in the NSW State Titles and finish second in the event. All of my oil gear diffs were filled with Kyosho 500 000wt oil.
I am now using the 3Racing oil gear diff in all three of my MO5's, two filled with 500 000 wt oil and one with 600 000wt oil. The diff with the heavier oil is being used in a MO5 being built for TITC in Thailand next year with the speed gear set. I hope to test this car out when I get back home from my work commitments.
So yes I believe the heavier diff oil is required in the gear diffs.
Anyway, happy racing and hope you workout some oil weights you like.

Ok I run the diff tonight with 2000wt kit oil in on the m06 and it made the car really push and was Basiclly un drivable fast. The same car last week with the kit diff was fine and that is all I changed. I am thinking of dropping right down in oil wt and giving it another go after I have proved the car is fine with the kit diff back in.

Tamiya mini coopers are made simple and cheap for a reason ! Gear diffs and their multitude of oil combos go away from simplicity , and only somewhat make up for driver insecurity and their need to try to make their wallet guarantee a podium finish ! What a waist !!!!!!!! That's the exact opposite of what mini racing is all about !!!!

I am surprised none of you converted your minis to belt drive ! What about rotary shocks ? Carbon wheels anybody !!! Lightweight antenna ! Exotek 2.5gram chassis ! Maybe M06 tc conversion!!! Why don't you guys just stick to tc racing instead ? Can't cheat your way to a trophy there either right !!!! Once a loser, always a LOSER !!!!!!!

Troll much, Bert? Wow.
Anyhoo, I took the gear diff apart and cleaned the stock maple syrup out of it. While tearing it down, I took note of just how much friction the shims provide on their own, with just a thin film of oil on them. LOTS.
I refilled with a 35wt shock oil (425cst) and found it was still quite sticky, so I chucked it up in my drill, held the other side in place and spun it at 500rpm for a few minutes. Afetr that the action seemed about right, so I've installed it in my M-06 and it feels about right when holding one wheel and turning the other.
We'll see how it goes on the track soon.

Who is this clown? He recently posted that he's using Losi lcd axles and ceramic bearings in an M-03.
Bert, you're capable of offering good advice. You're better than this. Cool it, would ya?
