Bringing this post back from the dead. I'm on a time crunch to clear out the work benches so here we go. Got the steering all figured out with a High torque Titanium gear servo, I think the machine was missing some parts and mounts for it so had to make all from scratch. Got the glass all cut and mounted without any issues for once, measure 7 times and cut once. electronics all installed and working on figuring out the lights and beacon. Some scrap bruder bits were mounted to make a cab interior and floor. Just a mild ballast in the roller, very happy with the way this turned out. Here is her first test run:
