Well. a real D8 has a recoil spring built into the track roller frame that allows the idler to move back when just this sort of thing happens.., a small feature I forgot to include on the build..

It stalled the track a couple of times both going in forward and reverse, and then things went very silent..Those little window motors have enough torque to pull apart a #15 steel roller chain..A fairly easy fix, but the power exerted surprised me..

But it was a nice day and it was great to get out and play..

Had that happen just once (I've been lucky) but the spockst will pack the rails tight if you don't watch it.

We need a video of you rolling out a big clay ball.
