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.
