i have to do this little beast, because i dont have any tank from the world war II.I want to join historical RC battles, so i have prepared this.
Classic gearboxes dont fit to Hetzer, because frontal armor is too close to the axle.
I have used geared JGA25-370 geared motors and closed belts for 3d printers (GT2).

There is 4 servomotors inside - two of them for the horizontal and vertical movement of the gun, one for the reciol and one 360° servo for the machinegun.
I have figured out a design for the workable gunners periscope and workable hatches.3D printable track tensioner is a standard for my builds.
I have printed a very first prototype in configuration "everything printed" - with 3D printed jack, shovel and other details.I will try a version with a accessories maded from the steel (later).
This one is printed with the 0,3mm nozzle, 0,1mm layer.Materials ASA and PET(G).I have used XTC-3D for the surface preparation and AMMO of Mig Jimenez colors.
Photos from the inside coming soon
