Taking the idea from AEG's precocking, we removed the henglong BB launch unit and put in the DIY gear box.
This unit shows the actual motion on the tk 7.0 board.
The operation control used a timer relay and a constant voltage circuit in units of 10 ms.

kanggj2, you will fit right in with the 3D printing and electronics experts here on RCTW. I build on a more humble scale and check nearly every day to see the remarkable work you wizards manage. Build on!

I would love to see a lower profile BB mechanism for tanks with accurate barrel recoil become available. The HL one is so bulky that it prevents most tanks from achieving the correct amount of elevation by bumping into the turret ring.

I don’t have a printer nor do I see one in my near future, so I’ll just twiddle my thumbs until then.
