This is Soviet experimental offroad vehicle model has a 1/20 scale and based on WPL components. I made axles on leaf springs instead independent suspension because it was easy way. There are 2 speed gearbox, two DIY transfer gearboxes and a lot driveshafts.
3D model was converted from Spintires mod and edited in Sketchup.

* Radiocontrol as you wish
Front and rear axles has a steer and damped by leafs. Short driveshaft connect main gearbox with rear tranferbox. Between tranferboxes I puted DIY extended driveshaft. You can use universal joints ([like this](https://www.banggood.com/Metal-Universal-Joint-For-RC-Cars-Boats-p-87379.html?rmmds=detail-topright-recommendation&cur_warehouse=CN&ID=49366&p=J7171269288462016106) ) with a long steel rod between. Transerboxes has 2:1 reduction and connected to axles through driveshafts. A middle axle transfered power from both transferboxes for less stress. These driveshafts must be shortened as example photo because its not fitted.
Transferboxes assembled with plastic gears, custom shafts and a lot 623 bearings. Shafts made on the lathe and flatenned by file.
Notice: rear transferbox has 2 small gears and 1 big, front - 1 small, 1 big. Also need to check shafts rotate directions before installing axles.
Optional, I add [3d printed winch](https://www.thingiverse.com/thing:3134362) but made it smaller to fit into chassis.
