Team losi mini lst 2 ( mlst2 )
 

anyone have found a fix for the plastic diff spiders gears and side bevel ?

there's a fix on the beatyourtruck forums. cheap and easy. search for the optimus mod.

WOW! 18th scale owners found out how to put a shim on a diff! Wow... :lol:

heres a link to the "mod" - http://www.beatyourtruck.com/forum/s...ht=optimus+mod

What might qualify this as a mod is that the shims are "spring washers" - http://www.mcmaster.com/#9712K58

the mlst2 has metal diff spur/pinion gears iirc so shimming the diffs should stop the problems.

I tried everything to fix the diffs on the mlst1... Hopefully the mlst2 has better diffs stock, but I doubt it will ever be really able to stand up to even a mild bl setup...

Good luck, and post your results!!!

this is the proer link which describes the mod: http://www.beatyourtruck.com/forum/s...ad.php?t=52059

imo, the vendetta line has good diffs and overall strong parts. That and the xtm rage are the 18th I recommend. Get the xtm if you want a mt and the vendetta if you want a st, buggy, or touring car. The xtm rage has a bulletproof stock drivetrain and the vendetta, after steel cvds and possibly ball diffs, is a solid car. I had a Neu in my vendetta st..

Any car you'll buy needs some kind of upgrading. I loved my MLST2, it handled really well off road and was real fun to drive.

Yes.

Sell it and buy something that wasn't thrown together in 30 minutes by a bunch of money hungry apes.

Seriously though... the MLST2 diff pinion and spur were solid if shimmed properly. The internal plastic spider gears hold up a little longer if you shim the diff together and make it feel like a 'limited slip'.

Now you just have to fix:
-The horrible steering
-The center diff made of cheese
-center transmission idler made of cheese
-worthless stub axles, even the MIP ones bend when given a stern talking to.

EDIT: Oh, and boil any plastic gears.

Not to jack the thread, but I would recommend the xtm rage over the mlst. The only thing the mlst has on the rage is parts support. The xtm rage doesn't need anything out of the box. The parts are really strong and the drivetrain is really solid from the factory. Imagine a mini quake with all the bugs worked out.

thanks for all the info guys :great:

sell it. I spend 2 years trying to make those diffs stronger. With a mild lipo/bl setup (I am by no means one of those power freaks) the spiders wouldn't ever last a whole run.

Wait for the 1/16th scale e-revo :D

the mlst2 diffs work great, mikey84's is holdong up well to his monster setup

anyone can provide me this info on the mini lst 2 for the online speed calculator ? :

Enter Front/Rear Differential Gear Ratio

Enter Transmission Gear Ratio

im using all stock diff gear and for the center diff I use a spool.

iirc it is the pinion gear teeth over the spur gear teeth for the diffs.

Dun get the center ball diff. I had one MIP but it slipped so badly even when I had it tightened all the way. The mini-lst is simply too heavy for the ball diff. So I used the spring washers from the ball diff kit on the stock plastic diff (spring washer mod from beatyourtruck). And it did held up under the brute power of a 380S 5100KV brushless motor on 3S. I took out the center diff to check it and it looked as good as new even after 10 runs. Slipper spur tightened to the point where the front wheels raise up slighly under full throttle. The stock center diff with the spring washer mod is better in transferring power to the wheels as it does not slip like a ball diff.

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 ? :

http://www.himodel.com/electric/HiMo..._B2040-6T.html

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
