Folks, I've installed an asiatam /taigen recoil unit as per this diagram.. The muzzle flash plugs into the mg fire five pin on the rx. I've wired the mgs in as per the diagram, bar that the coax is in a plug above the Hull mg to allow for turret separation. Problem is I've no mg's and the headlight flicks on and off, regardless of the main switch position. Any ideas?

Should add recoil and flash works fine, but is there a way to get the mgs firing on the gun button on the tx, and the 88 firing with the cannon button rather than up on the left joystick?
