Exclamation Steel CVD Bone part number

Finally got home and dug up the part number on that XXX-S CVD bone. The Losi part number is A-9970 "CVD Steel Drive Shaft XXX-S". Hope that helps

I've got the molded thrust washers on order, and I already picked up the mini 4-40 nuts, so I should be able to try it next week. My only concern is that the description you posted was one of three or four slightly conflicting descriptions on the TTT thread.

I'm going to call SoCal and try to get the definitive answer to just how it goes together, maybe I'll get Slim on the phone.

I guess I need to be enlightened, exactly what does the "slimdiff" do better than the stock one?

that's what I want to know too, I read a whole bunch of "the slim diff is the bomb...once you use it you won't go back" but nothing about what it actually does

It will improve nothing.

The double thrust bearings may provide some added effect...but noting special.

The molded thrust bearings are not used any longer, as the balls running on the inside of the outdrive help to keep the diff from "diffing" when the inside tire is unloaded. So I see that as a negative in a sedan.

And lastly, the belleville washers in the ()() order was proven to be a bad idea with the NT gas truck....I'm sure you all remember the fiasco when Losi shipped the truck early on, recommending the bellevilles to be installed in the ((((((()))))))) order, or in the ()()()()()()() order. The problems with this back to back order is one of the washers will invert, and lose its tension...the entire spring assembly will lose some of its spring rate....which will let the diff loosen up, and then slip. This led to diff gears melting in the NT.

Sounds to me like the "slim" diff is a step backwards.

Ok, here's what it does.

It actually makes your car float. Less drag because the wheels aren't touching the ground so you go faster, longer, etc... Pretty much all the same claims as the brushless motor crap.

Slim Diff Bad Idea

The local top racers in my area, say that this is definetly a bad idea and to just stick with the normal way of building the diff. So I am definetly not going to give this a try. Boy do I remember the XXXnT diff problems.

viper1,

I tried to contact Slim to find out exactly how it's done, but I couldn't reach him this weekend. I'll get in touch with him on Tuesday and hopefully I can find out the sraight story. I'll be sure to post it here as soon as I know.

hi i just recieved my xxx-s in the mail last night and started building today. everything was going very smoothly until i came to mounting the servo. i have a hitec 5925 and i cant get it to fit. i tried narrow like the instructions say then wide and even tried both with those rubber things off and i cant get it to work. did anyone else have this same problem with a hitec servo. i was thinking that i could buy another set of the servo mounts and use one side faced wide and one side faced narrow but before i do, do you guys have any ideas. also would the inserts that come with the car be any good with sorex tires.

I have the 5625 Digital on the car and I remember switching the mounts around and it worked fine.(no rubber grommets) Maybe the 5925 dimensions are different?
Hope you get it figured out.
