Hi, thank you all for you encouragements. The M-113A1 MRV is done, finished, finito . Oh, I could have spend another month making small details here and there to make it perfect but I want to move on to another project.
Here is a YOUTUBE video of the M-113A1 MRV in action during the workbench trials. It is fully operational and ready for war. It was a bit complicated to operate it while taking the video. Once the snow is melted, I will take it outside for a good ride.

Here are some pictures with electronics and tracks installed and tested.
I think I managed to make a rare and unique vehicle. It was a really complicated challenge with potential pitfalls at every step.

Ah these Tank Modellbau metal tracks... adding the pads with superglue was easy but they required a lot of patience and efforts to make them run correctly on the sprockets. The sprockets needed a lot of grinding to make the teeth smooth and accept the links.

I know, these are Nato M-113 tracks, not the US version used by the Australians in the 80s. But its better than Panzer III tracks for sure.

Pictures of the electronics. A Clark TK-40 is on the left panel, the small HL T-90 battery on top. I am really glad I was able to connect all the wiring and fit everything within the engine compartment while allowing all the features of the tank to work nicely.
The model features;
- Turret rotation activated by a 360 continuous servo.
- 76mm gun elevation, recoil, flash and sound
- Coax Browning machine gun with flash and sound
- Front lights, tail lights and interior lighting
- Servo activated rear ramp
- Speaker in the fuel tank
- Detailed interior, including driver's compartment and rotating turret basket
- Mato gearbox

The Flysky receiver is at the bottom of the engine compartment, between the gearbox and bulkhead. Lots of wiring.

Hope you enjoyed the build. I will post another video soon.
