I probably don't run mine quite that tight, it would be easy to overheat the plastic. I use the paper between the gear method, it has never let me down. Even running a spool in the center diff did not hurt the gear, but I'm not racing...

Default Diff fluid

What are you guys who are running the Tekno DM-1 conversion doing for Diff fluid? I'm seeing the 500k being run in the center diff, but what about front/rear? 5k/3K? Also, when doing mechanical brakes are you guys running front/rear disc, or should that even matter if you're running 500k center diff fluid?

Thanks,
Mark

Mark,
Most of the guys I have seen running the Ofna DM-1 as an e-car are using the 2 speed, not a center diff. Thats the beauty of the Tekno conversion it was designed with the 2 speed in mind.

My GT-E has a diff because fitting a 2 speed and brake servo is much tougher with the conversions that are out there for Kyosho's. I don't miss the 2 speed though, the MM with 4S and 2200 kv motor is plenty fast and will be ballistic with a 5 or 6S battery.

Tight tracks require lighter oil in the rear so the car will rotate. High speed tracks with fast turns need heavier oil in the front and rear. A good starting point would be 30k in the front and 10k in the rear.

I am running a mixture of mobil 1 bearing grease and 100k diff fluid in my front and center diff, and it handles very well.

Tylord, You're running the red mobil 1 stuff?

Thats what i run. Centre diff, i packed it with only mobil 1. Front I'm running a xrays active diff (so I run specific oil for it) rear mixture of mobil 1 and 3000 silicon diff oil.

Yeah, been watching that. Danny from Tekno is running cener diff with 500k, but I didn't ask what they were running front/rear for viscosity. The 2 speed is going in the box. I moved all the components to the tekno chassis last night. I just realized with the snr shock towers there's not much for adjustment of ride height.

Which mobil 1? Going to pickup 500k diff fluid on the way home tonight.

Yeah I have been running the Mobil 1 with a 25% mixture of 100k Mugen diff fluid. I used to run the 500k diff fluid but like the Mobil 1 more. I run this same mixture in both the front and center diff. I haven't tried the Mobil 1 by itself yet, but plan to this weekend.

The Mobil 1 bearing grease is bright red and is very cheap. It can be found at any auto supply store. Comes in a tube or a silver can. You can even buy it at Amain.

Wow 100k in the front. What type of track are you running it on ?. I run mainly oval, so I thought to start off with 30k up front.

I run on a parking lot track that is basically set up as a large 1/10 scale track. It has a couple of large straights and a big sweeper, but other than that fairly technical. I like having the and exit speed out of the corners. It feels like my 1/10 car set up this way.

Did you run at socalrc events?

Oh, one other setup question, what do you guys run for ride height on these? I don't think 6mm is going to cut it.

I am going to be attending the Socal events soon(single full time dad so its tough), but for now, a few of us at work have a private track behind our warehouse. I work for an RC company so driving RC cars all day long is part of my job. I can't complain.
