Wait a minute! the diff suppose to be loose because you want diff action when the car is slow, once you carry enough speed or the shaft has enough concentric force then the clutch will engage so it would be like a solid axle and it will rocket the car out in a straight line. So you might want to use something else instead of diff oil like those high temperture lube for or lube for diff gears so it would wear out the bevel gears! I am currently using Hyspin Lube in my diff case it works good, consistant and smooth!

For some reason I was using diff oil (tried different weight,5k, 10k, 50k and 100k) but after like 20 tanks of fuel the diff become tighter and everytime when I open it up it seems like the diff oil is mixed with some metal power so it thicken the oil and I found wears on the bevel gears. (did the mod to make sure it is seal too, so it is not dirt that going into the diff case)
But after I switch to the Hyspin Lube, problem solved diff action is still so smooth after 15 tanks of fuel. If I were you I would use those lube instead of diff oil.

dtm: Can you tell me how heavy is the V One RR kit (the box with body and tires)??Will it over 2kg??

manticore: when you build the Negative Diff, did you put those red soft plastic rings in b4 the thin metal shim? i didnt put any oil in my yet, but its not spining freely when i turn the out drive cup, did i build it right?

Manticore

I am not sure about the V1R version but with my MTX2 version, I dont use the nylon washers that come with the kit. I use the original steel washers for the small bevel gears.

ME-student

manticore: my manual show to put the the red ring and then the metal shim and then the pin.. yours is the same?

Manticore

i dont have that paper with me !! I trashed it long time ago

by the way, that soft o-ring doesnt do any thing to lock your diff up !! it is just the thick nylon washers pack the bevel gears much closer to each other and that makes the diff tight

ME-student

manticore: yup... thats what i meant... i got it right then... what weight oil do you put on yours?

To answer your question on behalf of Manticore:

We both use Racer's Choice Hyspin Lube #7016 as diff oil. We both didnt use Silicon base diff oil instead we use the above mentioned lube.

I have used the Hyspin Lube in the negative for appoximately 20 tanks of fuel from the day I got it and the diff action is exactly the same as day one and that tells me the lube is doing it's job, no gear grinding and no metal powder cost by gear grinding mixed with diff lube(in fact I opened it up like a week ago and the lube are still white, didnt change to gray, when I was using silicon base diff oil, after 10 tanks or so the diff oil became gray and thick, it was mixed with the metal powder which cost by those bevel gear grinding, meanning the silicon base oil did not do it's job.) So far I am very happy with the lube.

Just one advise, if you are going to use those Hyspin Lube and when you set it up just put enough lube on those bevel gear not to overfill it like regular silicon base diff oil, then work the lube on the bevel gears then after the first run open it up again and add some more lube because by then the lube will most likely cover each bevel gear pretty good and will probably running kind of low! I mean at least that's what I did and it works good!

Hope this will help you building a perfect working Negative Diff!

Ah10: tks

me: you can get the hyspin+ from Jet hobby.
