LOSI LST XXL Conversion ideas

[jpoprock]

Yeah, I'm gonna have to. I didn't figure there was a way to know what it was visually. It's hard as a rock though! So I think it might be really good stuff.

I had a bearing blow in my LST2 last week, and now something else is wrong with the truck. I've tore both HD diff's apart AND the tranny and found nothing! But when I drive it, I get a clicking sound like it's a blown gear... but there aren't any. So.. I'm not sure if that is a bearing going bad somewhere, or what. I can't seem to duplicate it while it's upside down, or manually spinning the tires myself. It only happens when the car is on the ground driving. Maybe I don't need to be concerned, but it bothers me that a strange sound is present that wasn't there before. I just can't find the source!

It might be something else but it sounds like a pinion has broken a tooth or two in one of the diffs. It's hard to see sometimes. You have to open the diff cases and clean the ring gear and pinion and inspect thoroughly. Use a magnifying glass if you have to.

I tore a tranny apart and rebuilt it once because of a noise. I put it back in the truck and still had the same darn noise. It turns out it was a rock stuck in the spur gear, and I rebuilt my tranny for nothing.

Start with the small easy to get at stuff before you dismantle your whole truck!

I'm pretty sure my diff gears aren't blown. I inspected them pretty closely. Usually it's the output pinion that has broken teeth. But when I didn't see any, I inspected the gears inside the cups. Nothing! I even took the rear diff apart twice! I'll look for rocks next. Beyod that, I may swap diffs as well as carriers with stockers to see if it goes away.

Swapped my rear diff for a brand new diff, and no more clicking noise!! So I took a third look at my old diff and found it wasn't from broken teeth... But a section of three or four slightly stripped teeth! They had meat on them (but were clearly flatter at a certain angle) then the others. So even though there was a mesh, it was causing slip under torque.

Smooth as silk now though!

does anybody know if the rc raven springs will fit integy LST shocks?

I made the top chassis plate with wings. I like it. I wish it was CF but I didn't have any left so it is aluminum. It is 42 grams heavier than the stock plate. I thought I had bad bearings on the truck. It wasn't the bearings, it was two CVDs with cracked and broken parts.



No more brackets for the battery boxes, the top chassis plate and small aluminum angles is what holds the boxes real solid like.

Effing WOW! That is nothing short of amazing! Dude, I didn't think it could be done, but you have topped yourself yet again! Now, as soon as you get some more CF and remake it out of CF, I will probably just quit making parts because clearly you are the KING!

[suicideneil]

you have topped yourself yet again

Nooooo! Hang on, how can he kill himself more than once?

That looks factory its so well done, beats the heck out of the actual factory conversion

[jpoprock]

Ray... Do you trace the template over the aluminum by hand, with that knife shown in the picture, then put it on your router? Do you use the same type of bit (Tungston) that you use for cutting your CF? I'm just asking if that router table method is the same for aluminum as it is for CF. Thanks!

[jpoprock]

Man... that truck is AMAZING now! I can't believe how great your new idea looks! The only thing about it that I don't understand at all, and quite possibly could never come close to duplicating, are the angle brackets. I have no clue how you made them!

I don't own an LST but my revo with the steering mod is around 64" which I guess could be considered alot if you drive both and can notice the difference--Josh

I reworked my rear motor support system with the other half of the HPI Flux motor mount I had left. The screw for tightening the clamp and the screw that goes through the bracket to support the motor are now on the same side and I think it looks better and cleaner. This system is working extremely well by the way.

You might notice that there's a little bit of a rough edge in the opening of the top chassis plate for the steering linkage. I had to grind a half a millimeter off to clear the linkage's ball cup. It was knocking on the side of the opening at full steering throw. I corrected the issue in my drawing and I also made the opening for the diff's output cup a little less deep so that there is more material left between that opening and the one for the steering linkage.



The more I play with this truck, the more I like it. The way it handles, the way it jumps, the power it has and how easy it is to work on. This thing should be named Permagrin.

AH -I never noticed that your steering linkage was on top. I scratched my head for a while trying to figure out why you had to make a clearance for it.

Nice work.
