I've opened up the tank, turret and wiring and everything is in the right place, except for one cable that might be a ground cable, but there's no place for it to connect to on the RX 18, any help? I'm using the current RX 18 that has the dual sound sets. The flash unit works just fine, its the recoil and gun elevation which doesn't work

You could solder a wire to the negative under your board and connect it to the turret earth wire,( AT YOUR OWN RISK)

What does that negative look like?

Under where the black battery wire plugs in

hi
number 1 this lead fits in CN2


number 2 this lead fits in CN3

number 3 this lead IS THE BIG RED ONE SOLDER TO BLACK NEG ON THE ON OFF SWITCH

number 4 this lead is the 3 wire elevation motor control in older tanks this is on the small square board in the new tanks its the black 3 pin plug next to the 8 pin

Following Forgebear's schematics, and the advice on attaching the ground/earth cable you should find everything working. A piece of advice, though, efficient electronic contacts can depend on clean terminals. If I were you, I'd get a can of contact cleaner, and some absorbent lint free cloth and give your MFU and other parts a good clean up (with the battery disconnected). AK47s may well work with a receiver full of detritus, but electronic contacts and junctions can begin to work erratically- or not at all- when dirty.
Good luck with all of that

But make sure you have harvested the potato crop first....

Naughty boy.

Didn't quite work, though still working on it

This should give you an idea, the red wire from the board goes to the turret, you need though to clean where you are
working as solder doesn't stick well to mud
