~1:12 Miller Century M100 Rotator wrecker

Other random bits. Front axles are limited and ratio'ed by a baby Arduino (blue in pic), ie the frontmost turns more than the second.





Drive is only to the rear two axles. There's also a tag axle which is a Chinesium Tamiya-type trailer axle, split with a printed U-shaped center to clear the driveshaft.

Motor is your basic 540 type, 90T, with a 4:1 planetary reduction on the end of it. Could prolly use a bit more even.



Of course, this means there are three different tire sizes: fronts are super singles, rears are regular duals, and the tag is a bit smaller to clear when lifted. The tag also took a printed center hub since it's a single and the wheel faces the opposite direction to the rear duals and none of the ones I had fit right.

I've taken to using the Chinesium metal wheels since they're cheap and look nicer than the printed ones I used to do (though for the military trucks with beadlocks and such, still gotta print.)
