Hi
I’m now on my second 1/16th tank now, a King Tiger (Tankzones own kit) and I’m being a little bit more ambitious with this one.
It’s running on an IBU3 board and Flysky handset. I want to add a third machine gun on the top of the turret but I’m not sure how to do it regarding the electronics. I’ve got the LED’s and fibre optics sorted but not sure on the wiring. The Ibu3 board has a second machine gun facility on the board and I want to run the third machine gun from this to. The aim is to switch between the turret and top machine gun (the hull MG is ok).
I’ve been looking at rc relays and switches but I’m not sure what to use. Can someone help please?
Regards, Keith

Hello Keith,
You can use this one : https://www.banggood.com/it/RC-Lander-L ... rehouse=CN
and a relay (double switch contacts) like this https://www.banggood.com/it/5Pcs-HK19F- ... mds=search
where the coil is connected to switch output (red/black) wire, common contacts to two wires coming from IBU 2nd MG led output, N.C. contacts to turret led, N.O. contacts to top turret led.

Ok, thanks for the info.
I'll have a look at these and let you know how I get on.
