Looks like you got the spring rate figured out pretty good to balance the torque twist vs. flex. This is always a struggle on my crawlers. What are those springs off of?

Your crawler is improving daily it looks like. Nice work.

Springs are from a 1/43 SSMT shock, I had a few scrap shocks laying around.

As for improving daily, sadly not, I did my best to hack down the rear end, to drive the idler straight and I pretty much ruined the whole project. I'll figure out a way to get it back on track soon enough though I'm sure.

Any videos of the truck with the SE servo straight to the idler ? That's what I'm planning to try again next, and I'd love to see the speed.

Thanks for the kind words and advice, I'll see what I come up with bringing it back from the parts bin.

Post up a pic of the damage. I bet it's saveable. I shaved mine down pretty low when I ran the gearbox direct. All the latest videos with the gravedigger body unpainted and painted are with the se gearbox direct to a green final drive gear on the axle. If you need more speed you could run a an orange gear on the axle but you may run out of clearance to the pinion on the axle. I'd try the green and work my way down ( green, red, yellow, orange )till I liked the speed and/or it still fit. You can always shim it back up with some plastic and 5 min epoxy too. The drawback is that the gears on the axle cannot be changed between colors/ratios without trimming or shimming but it may save your chassis.



You can see in this pic how I trimmed right through the cover on the stock gearbox. I'd ran it this way more to lower the cg than to crawl faster. This set up has plenty of power, less weight and lower cg.

If you've still got or can get an ssmt I'd be interested in a trade if you need parts or whatever. I've got a 1/20 scale FJ40 that's beggin for some ssmt axles.
