Leopard 2A7V. From a static kit, to an RC model. Hopefully! Or a pile of scrap plastic.

Part 1.
Despite my own self imposed rule of only building one model at a time, and completely finishing it before starting a new project, I purchased a Das Werks Leopard 2A7V with the sole intention of converting it to Radio Control. I make no bones, about, reading, and re-reading Imcq11’s builds, to glean ideas. Especially his build on the Takom/Andy’s HHQ M-113

Starting point is the 1/16 Das Werk, Leopard 2A7V, and a Heng Long Leopard 2A6 chassis.

I am hoping to install working lights, smoke and flash, recoil, HL TK7.1, working machine gun, ball bearings in the suspension, and wheels, with torsion bar suspension.

First decision was to see if the HL hull could be used in its original configuration. The upper hull does fit, but some trimming will be needed.

This would be incorrect, but a simple, working solution.
The simplified HL, is not as well detailed as the Das Werk, and it also has incorrect suspension.

The Heng Long lower hull will provide parts like return rollers, sprockets, motors, and track tension.

Part 2.

First thing was to install bearings in the outer side part of the hull. 4mm x 9mm x 3.5mm flange bearings were obtained, as was some plain bearings.

Along similar lines to Louis, brass and plastic tube was used to make a prototype suspension. 1.8mm spring wire was used.

This felt a little flimsy, so a second bearing was installed. This gave the required support.

Now a working system has been found. 14 Individual suspension arms have to be made. I now need to work out how to attach the main road wheels.

Part 3.

This is the Heng Long Leopard hull being stripped of parts. I am hoping to adapt the track tensioners to give a workable design, so the idler wheels do not have to be removed.

It also appears that the return rollers could be used.

Finally I am investigating the installation of the motors.

Lots of measurements will be required then ordering of the correct sized bearings, plastic, and brass tube.

Interesting project and looks like your off to a good start
