Ok so I go the Mini E-Revo center diff...section off of e-bay.

I also got the Team integy Mini E-Revo center Drive shaft..
Image

And will soon get the Mini E-Revo Center Diff
Image

The problem I'm having now is getting the Mini E-Revo center drive shaft
into the Mini LST drive cup..
The Mini E-Revo drive shaft (on the right) is just a little bigger then the Mini LST drive shaft (on the left.)
Image

The center Merv drive shaft fits in the opening and actually catches and can turn the wheels but it's not far in enough..
I am not confident it won't wear out the cups and fall out.
The drive cup actually bevels inwards stopping the Merv drive shaft from being inserted farther in.
Image

Image

The question here is do I dremel down the inside of the Mini LST Drive cup or do I dremel
down the end of the Mini E Revo Drive shaft.

Ok I got the Viscous Gear in to the rear diff housing and it fits perfect,
and I was able to install the Integy Mini E-Revo Diff Cup.
So it's a go.. Moving forward with the project. Now I need to do the front diffs
and work on a Mini LST Chassis that will hold the Mini E-Revo Center Trans.
Oh will also need to replace the Mini E-Revo spool with the Mini E-Revo Center diff.
Here are some pics below.

Here is the gears side by side.
Viscous gear on your left and the stock Mini LST gear on your right.
Image

Here is another pic of the two gears side by side.
Image

I also shimmed it. Here is a pic with the shimm in place between the bearing and gear.
Image

Here is a pic of the viscous gear in place in the gear box.
Image

For good measure here is a pic of the Mini LST Diff. I shimmed this as well but did not get a pic. I thought I did but did not. The shimm would go on your right between the bearing and the shaft cup.
Image

Here is the gear box with the viscous diff installed. Also the Integy Mini E-Revo cup on the bottom and the Mini LST cup above.
Image

And here it is with the Integy Mini E-Revo cup mounted on to the Mini LST gear box.
Image

Here is a pic of the Mini LST rear end.. done deal with Viscous pinion gear and Integy Mini E- Revo Cup.

Now I'm wondering Which way to mount the motor..
Using a Mamba motor I have the option to
Mount it towards the front or towards the back.
Either way space will be tight. I kind of want to mount the
motor towards the front. That way I will still be able to use the
Battery Tray, but the motor seems to be hitting the Servo.
I will have to see how far forward I can move the front end and still
have the drive cups connect with the center dogbones.
Below is some prefabrication pics.

Here is the Pre Fab Mini LST with Mini Revo Trans with out the motor.
Image


Here is the Pre Fab Mini LST with Mini Revo Trans with Mamba Motor Towards Rear.
Fits but really tight and If I mount it this way I wont be able to use the battery tray.
Image


Here is the Pre Fab Mini LST with Mini Revo Trans with Mamba Motor Towards Front.
The motor is hitting my 1:10 scale servo, but I might be able to fit it this way by moving the
front end forward, just as long as the center dogbone connects with the front drive cup.
And this way I will be able to use the Battery Tray.

Here is the Pre Fab Mini LST with Mini Revo Trans with Mini Revo Motor.. Does not fit either way.

Wow this is really a major undertaking but im betting the results will be worth every second youve put into the fabrication...Just my quick .02 from my quick glancing....if you mount the mamba over the battery tray it looks to me like you could mount a two cell small to medium length LiPo stood on its side right there next to the servo...a little zip tie or more fab work and that might fit into the space you have left without going higher and making your center of gravity even higher...again just a thought.

I will be tuning in with bated breath this is a very cool idea....how much did the Merv stuff set ya back anyway?

Man this is going to be one bad azz MLST.....Keep us up on testing, this looks like one of the coolest project undertakings I have seen in quite a while!

I am curious how well the Mamba will hold up to this set-up. I have had some heat issues with my 6800, when asked to push larger and heavier tires, over-weighted chassis and when geared too high. Using less gear solved most of the issues but also lost speed, I imagine an added cooling fan would have worked as well...The added weight of your set-up (well perceived weight, as I of course have not weighed it) and more gearing and rolling mass of the merv tranny may be a non-issue, but it has me curious none the less.
