[MOC] AMX 13 75 (RC)

I present my latest model, the French AMX 13 75. This is a rather unusual tank because of the turret design. The turret is called a oscillating turret, as the entire gun/turret elevates as a whole. This allows for mounting of a larger caliber gun in a smaller turret. The AMX 13 also features a autoloader system that loads a round from a revolving magazine. I had attempted to replicate the autoloader in the vehicle, but there wasn't enough space to mount in the turret.

The entire model's hull is filled with power functions elements, and suspension components I had several cases where the wires were packed in next to gears.... that ended somewhat badly. A few minor scuffs and one case of a wire being exposed, but they still work fine. The suspension is similar to my GW tiger's, as it uses Lego springs instead of torsion bars, the width of the inner hull is mostly 10 studs, and 8 studs wide by the suspension though most of the model is 10 studs wide. This created challenges for mounting components, I had to mount the drive motors at a angle, and the mechanisms for the turret had to be very compact. The gun elevation is controlled by a small linear actuator at the turntable, and the entire turret is a mess of different technic connections to allow for SNOT work on the outside. I am pleased with how well this model turned out for being built in under 3 days during a small break from college. One thing I wish I could have changed would be if there was a slightly larger road wheels (around 4.5 studs in diameter).

Enjoy, Tommy Styrvoky

Hello Tommy,

your tank is amazing... I like that type of models... You must spent a lot of time on details... and there is always problem with putting all the stuff in the body and hide it... Good working suspension and turret... Very good work... I like it very much... :)

And great photos too... :)

Max...

Beautiful tank! I love how you chose a more challenging tank to build! Do you have any pictures of the insides though? I'd love to see how it all works.

Here's some of it's internals

It's another beauty. Well done!

This is so good for only being built in 3 days!I am amazed! The tilted L-motors is a nice idea how that allows more space in the chassis for suspension. When you showed the insides and the mechanics of the turret all I could say is WOW! About the wire casing I feel your pain :-( But it still works :D

Great job. Are the shocks mounted horizontally under the motors? Is there one shock per road wheel?

[radar92]

That's awesome.

The integration great

one per two road wheels.

Nice build! The suspension is quite interesting - it's like a natural evolution of a torsion beam. Is it based on the one found in this tank?

By the way, the outdoor pictures are very good. The blurred background makes the tank really stand out.

The suspension for the real AMX 13 is torsion bars, the design I used seems to work well for having many swing arm next to each other without having issues with them getting caught on themselves when placed next to each other. This design offsets the swing arms at a angle, rather than at 90° with most lego axles. Though there are solutions to have the offset with torsion bars, but they aren't as compact, my M4 Sherman Crab and Hetzer are a examples of the usage of offsets with wedge belt wheels.
