Making a LST2 into a Truggy

Something different! Dont you know, EVERYONE has an LST with a stock tranny or a center diff.......!!!!

The reading I've done on conversions tells me that getting spur/pinion mesh with "good" gearing is difficult to say the least with the stock tranny. And since I plan on running the 1520 in it, this will be even more difficult.
I also dont like the cross wise orientation of the tranny. Anytime you run your power 90 degrees, you loose efficiency.
I had been leaning towards a center diff, but after pricing the muggy diff parts on A-main, I was up over 100 bucks just for the Front and Rear. Bought a new 3905 maxx tranny for 40 bucks, and I can run the stock diff's.

The lst tranny is stronger than the emaxx tranny, plus it does not have to handle the weight of the motor. The slipper design is better too, IMO. I would like the top shaft redesigned for use of the tdr hub and some of the length removed. I will do this with my lst builds, just need to get some time...

I have yet to hear of anyone having significant issues with a new Revo/Maxx tranny. I love the Revo spec slipper system - but I must admit, my experience with it is in my revo conversion, which is probably half the weight that this LST is going to be. I have zero experience with the LST slipper - so I know not what I am missing!! Somewhere down in the Man Pit, I have a Strobe set up, so that might find its way out of the dark on this build...

I'm viewing this as a trial run - long term I'll probably go back to a center diff. Money has been a little tight lately, and this offers a fairly inexpensive route to put this together.

The cases crack near the mounts, motor plates bend, and you have to use modded mgt gears to run mod1 pitch gears. Granted the 1st 2 issues are when you use a heavy motor and jump the truck. Not many people do that...

As far as the stock tranny not being as effecient due to the bevel gears, well you are most likely right. However it is stronger, and offers other advantages as well. No torque roll due to the cossways mounted motor either. The tdr mount is much stronger than the emaxx motor plate, no doubt about that. Plus you do not have to mod the chassis to use the tdr mount. So 40-50 bucks for an emaxx tranny plus chassis modding vs around 110 for the tdr mount and single speed hub... It is worth the extra for the tdr stuff, IMO.

And the strobe setup you refer to, is that the slipper? It only fits the old emaxx tranny, not the new one.

People have succes with the new emaxx tranny, and I do like it, and have used/will continue to use it in my custom builds. But it is not superior in any way to the stock Lst setup.

And I definitley plan on being one of those people - jumps and ensueing carnage are what this is all about!

I wasn't aware that the strobe only fit the old tranny. Oh well - guess I'll donate that to my brother in law.

I'm not sure that I will be using the maxx motor mount plate - I may end up putting the motor on a seperate mount so it faces the tranny and lines up down the center of the rig. I'm also not sure that I'll run Mod1. I have some of those modded MGT spurs somewhere in the pile. But all my other rigs run 32P, and I may just try to be consistent with them.

ps - I would never venture to say that maxx tranny is in any way superior to the LST tranny - since I dont have any experience with that tranny.

can't you just use nitro revo spurs on an e-revo/e-maxx tranny? that's what I used on my buddy's rustler to run mod1, works fine.

I don't know whether the FDR would be acceptable or not, but nitro Revo's run 34-40T spurs as not much else fits those trucks. But I do know they are alot smaller diameter than the 58-68T availible for the E-maxx/revo trans.

Ok, sounds like the erevo motor mount setup would work better for you. It is a bit stronger, but I would like to see an al case for that tranny as it does trake the motor weight however. Sounds like you have the other bases covered. Have fun with your build!

You can but they would be very small and I doubt you will fit smaller than 22t spurs, maybe not even that small if you plan to run a finned neu sized motor. The rustler 48p gears are closer to the size of the revo mod 1 spurs.

Exactly!

Cures that problem! Thanks for the link Harold (can I call you Hairy?). I am guessing someone makes a stronger motor plate as well. But....Once you add the cost of that tranny case, another tranny for internals(or buy the internlas piecemeal) and a better motor plate you have eclipsed the cost of the tdr stuff, and you still have to make stuff. And I still do not think it is as good. All of the internal gears in the lst tranny are steel, and to me the fit and finish is better than the traxxas stuff.

But if you like making stuff or have the parts hanging around go for it!!! It is fun building stuff!
