Hi. You can easily buy 24 wires slip ring on eBay for $ 18-25. This is enough to have a modern turret tank with all the upgrades ( servos, recoil and even IR receiver / transmitter ).RobW wrote:...The slip rings also tend not to have enough wires for recoil etc as standard so sticking to 340 can make things a lot simpler...
Of course, unless you are not afraid to solder a few required plugs needed to connect to the MFU.
The spare kits with pre-mounted connectors available on the market usually have 12 wires. Which doesn't even allow them to be mounted in the stock Heng Long Leopard 2A6 with 6.0 MFU. There you need a minimum of 13 wires, but in fact it should be no less than 15-18 so that you can add anything to the tower (e.g. FPV or an additional LED on the roof ... )
Cheers and good luck with your Leo
