There's no problem with the centre diff wearing anyway, the problem is the little spider gears in the F/R diffs. I never had a breakage of ring or pinion. I was running a mamba 25 combo - the 4600kv or 4800kv or whatever) and rhino 1000mah 3s lipo. it was pretty much guaranteed to shred one of the diffs every time I ran it.

The center diff will break if a 380S brushless motor is used on the mlst.

Try doing the spring washer mod on the F/R diff. I modded my read viscous diff with bigger washers to replace the weak original washer. This mod caused the bevel gears to be pressed tight against the spider gears. The diff action isn't as loose as before. It is rather gritty and tight but it doesn't seem to affect handling much. I had the mlst on brushless and did this mod when I first got it. Since then it has been almost 1.5 years and the spider gears hasn't broke once.

I did a check on the diffs 2 weeks back but it seemed that they have been worn out quite a bit. They look like they will give way anytime soon. The viscous metal ring and pinion gears are pretty much worn out as well. But not bad considering I run 2 or 3 packs through it every weekend.

That's good to hear, I just didnt have the same luck, I tried that mod along with many others. I nearly to totally customized it to run the mini inferno full metal sealed diffs, but realised at that point I'd spent about a grand trying to make this truck a little bit better than piss weak and had no luck, no I'll just wait for the mini-revo. Traxxas seem to have a knack for building their cars tough. I've never broken anything on any my revo or rustler. Traxxas pwnz losi :p

Sounds like u had a lot of alloy on your mlst and it got heavy. Anyway it is a known fact that the diffs in mlsts are simply too weak. Losi should be issuing metal spider gears instead. Anyway I will be getting a 1/16 E-revo soon and probably my mlst be left lonely on my shelf then.

mlst2 was stock, no alloy upgrades at all.

what a good 3s brushless motor for my mini lst ? I dont plan to paid alot for this.. im using a cheap one 7782kv ( the one that came with ) almost no-name I think LOL! and get too much hot fast ... my gearing was 60t/19t im using the stock tires and 1/10 sidewinder esc ... and my motor mount can accept 380 size brushless motor

I am using a cheapo $17 380 5100kv sized motor from himodel on 28T. On 3S lipo the top speed is just slightly lower than the 1/18 xcelorin 7400kv brushless motor with a 20T pinion. But the xcelorin motor overheats even with a fan. The cheapo 380 motor has much better acceleration (tons of it. my mlst can wheelie even a loose center diff). Although slower, I don't get heat problems anymore. The max temp haven't exceed 60c even in an ambient temp of 34C. I used a 35A ezrun brushless motor with it. So far no problem with the setup.

this one ? :

No. It is not listed anymore..

5100KV
Can diameter: 28mm
Can length: 35mm

The only down side to it is its current draw. It can draw over 40A under very hard acceleration with a 28T pinion on a mini-lst. But that is only momentarily.

this one sound like a good one no ? :smile:

Yeah that's the one i am using. Somehow i missed it. :D
