Brushless LST2 conversion - This is how to do it!!!

Also, the stock turnbuckles (on the RPM arms) are pretty weak so you'll want to upgrade to Lunsford turnbuckles as well but once you've got all that they're really tough.

I had a look at the lst arms from rpm and really do not like the shims needed to adapt them to the lst2 hubs. I will stick with the arms I have, and maybe upgrade when/if they cause me issues. I will most likely redesign the mounting to eliminate the spacers if I do go with the rpm arms....

Thanks for the lunsford tip!

I wasn't much a fan of the adapters at first, but after breaking my 2nd pair of arms I said screw it and bit the bullet ($100+ for the arms, adapters, and turnbuckles ).

No prob, I sheared a turnbuckle off after about 1-2 minutes after putting the new arms on and I had to trim down the plastic in order to extract the remaining bit of turnbuckle

I will see how it goes. I do not break much, but i do like to bash. I have a design to mod/strengthen the rpm arms in my head, so I may give it a try. Wish rpm made a solid upper arm, the trunbuckle looks like a bad idea, especially considering rpm's nylon blend...

I haven't quite learned the art of jumping my Muggy, so it sees a lot of bad landings

I wish they had a solid upper as well. I don't care about adjusting my camber, but I do care about straight-up durability.

This was my first time out, all things considered it held up well but I heard those kids yelling something to do with "run it over" and wanted my $1,000+ out of the way!

That vid was cool! I would love to have a track like that close by, looks like a blast. Your muggy seems a bit ass heavy, maybe move the batt farther forward on the chassis? I did a bunch of testing with the savage for battery placement, and farther forward always made it jump and steer better. That is why I put the batt in front of te tranny on the lst. I can't imagine how bad it would handle with the batt in the fuel tank position like most do it. That is just too much weight out back, unless all you want is wheelies!!!

Interesting how the lower arm broke off on the inside. I will run my truck with stock arms, and upgrade when they break. I may leave the stock upper arms and just swap the lowers... Who knows...

Thats a really nice conversion, but i think a Neu 1521 or a KB45XL would be a more adequate motor

The battery tray is very well made, the lipo is protected really good. The weight distribution with the lipo in front is also nice, other conversions are often so ass-heavy.

How does it handle? I've been reading a lot about LSTs as well and the weight distribution issues with the battery in the back. Just wondering how turning "feels" with the battery and motor mass positioned that way in a large vehicle.

Thanks, I do try to make em look good...

I am currently using traxxas 50k diff fluid, which seems to be just the right thickness to keep the truck straight and it still turns fine. It will lift an inside rear tire on hard turns, but it does as well as the revo.

Thanks, I do have a 1521 1y to put in. Honestly the hacker c50 xl has plenty of power, I even have the punch control set at 50%. No real need for more power, but I do want to run higher gearing. Plus the hacker will go in my 6x6 lst based project, as that truck will be geared for about 35mph max.

The battery tray was easy to make, just cut the kydex to the right shape with a bandsaw and folded the sides up with a wood block, bench vice and a heat gun. The rear mounted battery setups must handle like crap, way too much weight in the back.
