I would like to introduce the Leopard 2a6 comprehensive upgrade project.
I have upgrades such as gimbal barrel balancing.
Recoil-action BB pellets.
Smoke system along with BB ammunition
FPV camera for aiming system with adjustable crosshair.
I'm so happy that this project is almost finished and I wanted to share it with everyone. Thank you all so much

Those are some seriously impressive upgrades you've crammed in there!

Thank you )) Here are a few more detailed images of the system; you can check them out in my YouTube video.

Okay I think I see it now:

That metal tube on top is the BB feed line, that servo I guess allows one BB at a time into the chamber, and then you’ve got I think a solenoid valve that releases pressure into the chamber to launch it, along with a smoke system that feeds into the barrel.

Could you tell me more about how your solenoid launching system works, as I’ve been wanting to do something to increase the FPS of the Airsoft system in my tank

I took the air intake system from a mini car air pump, then bought a CO2 cylinder, emptied it to use it as a compressed air tank. Theoretically, a motor rotates the piston to draw in air, and a 12V solenoid valve is used. My system uses compressed air for both recoil and firing.

So the CO2 canister is empty and you have a pump dedicated to pressurizing that canister with plain old air, then the solenoid releases air to launch the Airsoft and recoil the barrel at the same time? What stops the air pump that fills the canister from running continuously?

Is that servo at the end of the barrel for recoil (I’m guessing not since you said you use compressed air for that) or for barrel extension, or something else?

If it is used for extension, why not use the servo for recoil and extension?
