Hopefully your bearings will stay intact :rofl::rofl:.

I feel like an idiot, I never stopped to think about the LST's diff ratio compared to the ERevo's diff ratio. I don't even know what both ratios are. Is there a big difference between the two? What spur and pinion would be good to run with LST diffs?

LST-43/13
Revo-37/13

the LST uses the same ratio as the hybrid diffs that Mike sells for buggys, and playing with your spur/pinion ratios will offset the diff ratios

Thanks for the info, I appreciate it. Now I feel a little less like an idiot. :lol:

I ran my 1.5D on 5s and it handled it just fine, but it didn't hit full throttle for much more than 1-2 seconds before it ran itself out of room. On 4s that motor (despite the 30k fluid in my CD) would put my Muggy back on it's wing with the front tires ballooned waaay out (40 series look spectacular when they're ballooned that hard :lol:) and on 5s I was able to backflip it over the wing. Max motor temp I ever managed to get out of it on 5s was 150 degrees, but it thermalled my MGM 16018 (160-180).

Ok so i have the Diffs mocked up in an extra set of bulkheads, but im wondering what i can do for a driveshaft to fit the LST diff and get on to the traxxas gearbox? Any suggestions. I toyed with using a set of driveshafts for a ofna buggy but im not sure if they are long enough. What is everyone using/planning on using?

I plan to use stock erevo sliders, and these to attache the sliders to the 8mm pinion of the lst diff.

Not sure if I will use the stock wheel driveshafts or not...

For center driveshafts I will be using Kershaw Design steel drive shafts. I have RC_monsters 8mm drive cups on the LST diffs and traxxas cups on the erevo tranny.
I'm also running traxxas cvd's at all 4 corners. I have respect for the guys that can keep the plastic stuff alive. I couldn't, trigger finger must be to heavy I guess. I will be trying traxxas new summit axle shafts very soon behind a Neu 1515 1y on 4s. I hope they work, becasue that revo is set up with the long travel rockers and adjustable wheelbase set all the way back. Not a rock crawler but I wanted that truck up in the air.

Oh dear! What have I done :whistle:

I was worried that with the material taken off the inside of the bulkheads, they would become too fragile so I did the best I could to reconstruct on the outside with melted Nylon Composite from a scrap bulkhead. I believe those rear bulkheads are now very strong but it looks absolutely awful. :lol:

fugly bulkheads


I need a plastic welder really bad.

Looks good:whistle:

You have the right idea though! Urethane Supply Company make some really good plastic welders, and their uni-rod is similar in material to the bulks, so it would be a good item to add for strength.

I checked the link you provided me for plastic welders and did a lot of reading. I know exactly which one I want, I just need the funding to get it. Thanks again for that link, it's great.

They have tons of info on that site. I have used the mini weld model 5 for at least 6-7years now and it has made me $$$$. A little expensive, but I can say that it has lasted. Have fun with it!

Ah very cool linc! I did try this but didnt like how much material needed to be removed so I scraped my attempt at it and went with the tmaxx bulks..

Fitting Summit shafts on the LST diff's 8 mm output shaft. Time will tell if it is strong enough. Summit shafts are way tighter than the U joint style Revo sliders. They don't have slop in them.

I have an e-revo and I want to do this mod. What do I need to buy and what do I need to mod? Any new bearings? Any new axles?
