Got everything over to the Slash chassis and mocked up. I've got some stuff ordered, but I've run out of funds so it might be a while until this sees some love. I do have tires and a body of sorts coming, so it'll at least get on the rubber and we'll see after that.
I like the idea of a cage, and definitely thought about it. Test fit my Exo and Yeti cages - not bad. Yeti especially looked promising, thought it would need some serious trimming. Looking for something lighter for now to get started. We'll see how it evolves.
I've never gotten a used roller that was so stiff. Everything was stuck, not sure of the PO dipped it in a vat of CA glue or what. Driveline was super stiff, and the suspension was so stuck I could pick up the chassis by one axle and get no flex at all, even without shocks. Never seen anything like it. I cleaned everything up, reamed the holes for the hingepins, and went turnbuckle by turnbuckle and got the surface rust off and freed up the pivot balls. Driveline was fine after a deep clean and soaking the bearings in some oil. They weren't gritty, just stiff. Everything moves nice and smooth now.
My workbench looks like a Traxxas hurricane hit it.

I've got more than enough parts for a 4th vehicle if I ever want to, and maybe a few short of a 5th. For now, the Trail Telly, 4x4 Rusty and this hot mess are more than enough to keep me busy.
Chassis as it sits. Basically the same setup as the Crawler telly, just longer and wider, and with a bigger outrunner. I had planned to use some big 2.2's, but I needed so much offset up front they were in the next zip code compared to the steering kingpins... that's never good for steering or durability, so I took the tires off the 2.2/3.0's I used before and got them mounted up. Plus, I love the look! Just waiting on some taller tires which are en-route. I totally forgot to dye the chassis black, I got in the zone and started building. I have to tear it back down and get busy dying.
