I won the auction for the chassis - 10 bucks shipped.

So I'm kinda rethinking my overall goal here. I started looking at the possibility of somehow incoroporating a tranny below the chassis (between it and the bottom plate). Wouldnt really be all that tough to do - just a couple of bearing mounts and shaft holes. Just have to figure out how to make it accessible if needed, and close it off from debris. But then I started wondering if there would be more value in designing something more mainstream (ie., a chassis and diff, or a chassis/BrandXX tranny) that I could then possibly give to Mike to add to his conversion list. I personnally have zero interest in producing items for others (its a hobby, not a job), so giving it to him to produce would be in everyones best interest.

What kind of thoughts do you guys have on this? The Dude mount kinda takes care of a standard LST tranny. But, one advantage of possibly going with some other tranny is a significant weight reduction - that LST tranny is one hefty beast. The Revo/3905 tranny would be a fairly easy config, and they are readily available. A Savage tranny would probably fit fairly well also. The Revo would be even better if FLM would make a plate for it like they do for the single speed conversion on the 3906 tranny (nothing but wasted space in it in a single speed config).
This could be a "kit" kinda like the CRT conversion kits.....

Can I bother someone into measuring the top chassis plate LOSB2287 from front to back and side to side? Thanks.

Which one is that - LST, LST2, or XXL? I have a pdf drawing of the LST top plate (Attached file), and will have one of the XXL shortly.
Print it on a 11x17 paper and it should be full scale.

Sorry I should have been clearer, I was thinking of the XXL top chassis plate. Thank you for the pdf file.

So I'll be getting my XXL chassis sometime in the next week, and should have the dim's on it late next week for ya.

My pile of new parts is growing into a daunting mountain of goodies - and I don't think I am quite done ordering things yet. Seems these trucks aren't quite popular enough that you can get everything you need from one vendor. So far I've used Mike, A-Main, OverdriveRC, StormerHobbies...and Ebay.

I got the Slipperential (50T, Hardened endcaps) assembled and installed in the Muggy today. Had to open up the slot in the chassis by almost double the width, and about .3" length wise. You also have to clear for the slipper.
I had a heck of a time with the teflon washer - just a hair too small. I put a small chamfer on the cup and finally got it forced on, but a piece of the teflon pushed back out. Used a screw driver and the end of a socket wrench to basically mold it back in. Another note on the slipperential - clean those screws before putting your threadlock on. They are still oiled from the manufacture, and your threadlock will do little with that oil on them.

Also got Mikes large batt tray installed - fit great on the Muggy, and still left room for the MMM right behind it. I do have to say, my 5S Neu's are a very snug fit in the tray.

Was planning on putting the 1515 2.5D in it, but as I was removing it from the 8T, I discovered a wire connection that apparently had been having some serious shorting. All along I thought I had blown a diff in the truck - it started hesitating on me periodically right after I jumped it off a 20 ft wall into some soft sand. I only ran it for another 20 minutes after this occured, and havent bothered taking it apart yet. I'll have to pull the connector off and solder on a new one.

So out came the brand new 1520....

I'm still concerned about bending Mikes motor mount with this thing. Just light pressure with my hand I could see movement in the mount. BUT....I still have to fab and install a top plate for the diff mounts - so that might help with that.

Just have to mount the reciever, and make some servo mounts (the Muggy didn't have any of the plastic screw pieces with it). Hopefully I can put something together out of the extra's off the LST.

I'll get some pics up later......

MC...I got the XXL chassis yesterday. It is quite a bit bigger - how accurate of a measurement do you need? If you just want a tape measure number, I can get that for you today/tomorrow.

Personally, I would stick with a centre diff but I can understand your thinking with the 2 trucks. Giving Mike idea's and stuff is great, I might do it myself.... but he may not like the looks of a lot of what is on offer
