3D Sets 4x4 powertrain improvements

This is a pack of several components for the 3D sets all terrain printable RC cars which have been modified to greatly improve reliability. This pack aims to never have your 4x4 3D sets RC stop again because of axle /gearbox couplings getting stripped/rounded off. No extra parts needed. This is just a component design change. I developed this for the Landy, but it also suits the Rancher and Bamboo models. Stock axle width only. This is in constant development. Any feedback you have will be used…
