sure, you mean the 2wd chassis? I'll see what i can put together. Note it will need an upper deck of some kind, i have a few ideas but nothing on paper yet.

Default we got a roller...almost!



got a little more done last night, the axle was pulled apart and rebuild with fresh gears and properly shimmed. Then i worked out the links and got it installed. I cut it really close on the chassis length and transmission location, but it just tucks in the back. I was worried that the driveshaft angle is too steep, and it's very close but so far it moves through it's range w/o binding.

Added rear shocks and cut up a piece of delrin for the battery holder. I plan on running a lipo so I'm not super worried about the weight and location, though for some reason i keep thinking i need the weight over the back axles - with 4wd, i don't at all - have to get out of that 2wd mindset!

have to make a top deck in the font of the chassis and start thinking about body mounting. Then i can take it all back apart for painting/finishing.

Very, very happy with how this is coming.





wheels on just for kicks. I have some minor track width issues to work out yet....rear is much wider than the front.






mocked up with my current Slash body

pretty well, looks very rear-heavy, but with the motor mounted low it feels a lot like a mid engined truck. find out for sure once i get it running...

I like the concept, spot on for realism compared to other offerings.

I think maybe the center diff-motor plate a little further forward would rock, but hey I'm here, your there.

To widen the front, how much do you need? There are the traxxas thick grey hubs, and then all kinds of wideners made from aluminum floating around.

In retrospect, moving the center diff forward would have made a ton of difference. What looked good on paper did not work out so good once built. Thankfully it all worked out...I'd cry if i had to cut all that back out again.

The front is ok width-wise, it's the back that's a bit too wide. I'm thinking the 15mm hub extenders are way woo wide, i fact if i use the front slash wheels with extended offset I may not need extenders at all.

can I beg of you for a straight shot from above, and another of the bottom?

Man, this rocks. I think I may look for a beat up 1/8th buggy for a donor...

sure! bear in mind it is still very much a WIP

working on the top deck..really not sure if i even need one, chassis is way stiff, but i'd like to tie up the front bulkhead and steering posts.

Thanks man, it's coming along well. i have to finish it before my 5B gets here as I'm going to be very distracted! I'll get some dimentions for the 2wd slash chassis as well.

Got a little more time in with the SX4...

I "machined" out the battery plate, and mounted the battery holders. I used only hand tools and it's my first attempt at it, so it's a little hack. Practice makes perfect though.. Really lightened up the plate, and the battery will cover it. I drilled out 3 spots for the battery so i can move it back and forth as a tuning tool, or mount a 7 cell pack.

I took off the center diff plate and made a new one out of aluminum. This doubles as a ESC mount as well as giving a nice spot to mount the top deck.

Speaking of, I took a page from my other tubing builds and the top deck is made out of plain old brass tubing. Light and plenty strong enough, I just cut up a few pieces to triangulate where needed, bent it up a bit and bolted it all down. I was going to make some sort of plate here, but i started messing with the tubing and it just sort of fell together. Glad it did, I think the tube set-up just plain looks cooler .

Just need some body mounts, then tear it all back down for some finish work and paint. Most of the chassis is going to end up black.

feeling the progress!!!




just trying out some wheels....love the tires, but the wheels have to go.

looks killer. small bit o' advice? how horizontal do the rear shocks get when you compress the rear end? when the shock changes angle that much thru it's travel, it does less to help you from bottoming it out, especially with the weight of a battery back there. maybe check out like a Wheely King sized shock, and mount it lower on the axle, with the lower link? keep it a little more vertical, for the bump absorption, but longer to keep your travel. i think it looks fantastic though!

I don't have a template per-se, but the chassis is 55mm wide and the ends, 75mm in the middle, and 392mm long.
