Why in the world would you NEED to run medium wheelbase? No big difference in handling. If this is some kind of rule, be sure to slap the guy who made it up.

You can't run oil in the stock gear diff, it will find it's way out, sealed or not. Use some heavy grease, like Tamiya anti wear grease to tighten it up a little.

i mis used the word "need". Anyway, got it figured out.

Got my 3Racing gear diff today. It's a decent piece. Goes together easily and seems solid. I must admit to being a little miffed that they didn't include the 10x15mm bearings. Would've been a cheap way to provide a complete kit. Have to wait a week or two to test now. Damnit!

What would be a good lightweight oil (cst scale pls) to run in a diff like this? It came with some fairly thick goop, but this thing's going to live in my M-06.

My buddy that races touring car gave me a set of his low profile jayco blue groove rubber slick tires to try out on my M05 at the races tonight and WOW what a difference that made on my car! There was no spinning or chattering. It was faster too. The only thing was they were a bit to tall. What kind and part number of mini size slicks do you guys like to run? Any advise will help.

Thanks guys!

Adam

what about the bearing size? JRX-S drive shafts do not run on 5x10x4 bearings


They don't? Rcmart states it does :S Anyway, head down to the Australian forum, Lots of active members there!

The losi lcd(losa3333) are for the XXX-s not the Jrx-s , and they fit nicely in the plastic bushings in my M03 . It seems that the original M03 axles are slightly bigger than the lcd's , but the M03 is hardly a precisely built car ! A little axle slop won't hurt if the bearings are properly shimmed . I plan to buy Acer ceramic bearings for my M03 , and hopefully everything will fit nicely ....Had I known about Yeah Racing ecs drives beforehand, I would have never gone through all the troubles of fitting the lcd's in the front of my M03 !!!

Fluffy622,

We use 55mm slick tyres on asphelt here in Australia. Up front we use the Ride 3035 and on the rear Cross 36 with either a round or square edge. I only use the Cross Rims where possible as I like how they work. A Spice insert works well. In cooler weather I would change the front to a Ride 3027 and the rear to either a Cross 28 or 24 for the rear.

Others have used Sweep 40's on the front with Sweep 25's on the rear with pink inserts. These tend to wear faster than the Ride/Cross combination.

Hope that assists.

Anyone with any experience with the 3 racing oil filled gear diff ? I am going to run it in the m06 with the kit 2000 oil. Just wondering if this should work on carpet ? I also have 20000 and 100000 if needed.

The setup is for M05 or M06?

Also, who sells the cross rims and tires in the usa?

Look up 3 or 4 posts. The oil that comes with it is way too thick for use in an M06. I'll be refilling mine with some thinner shock oil, probably in the 500cst-750cst range.

Ok well I have it installed with the 2000wt so will at least try it tomorrow night and report my findings. If its really dog I will switch back to the M05 for the rest of the meeting.
When running a gear diff in the rear of my Xray T3 I was using 20000wt so wasn't sure on rear wheel drive only.

I run 2000 in the rear and 50000 in the front on my Zero S. It uses some of the same 3racing diffs parts as the new one for the M05/06. I was thinking the same, start with 2000 and adjust up or down from there.

Jim, the new brushless motors will change the setting too. If the new motor has as much torque as you say, we might even go thinner with the oil. My diff will be here this week sometime. I am looking forward to be able to tune the back end of the M06. I noticed a big difference going from 2000 to 3000 in my VTA.

Try it out. The way it sits, it would be great in an m05. It's as locked up as my ball diff. I suppose it will take some real world testing to nail it down.

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.
