does anyone of you have the setup above?
I have the base functions running but would love to have the machine gun and cannon on the VRA and/or VRB.
Found this:
<<If you've got a radio that mixes channels, simply slave an extra channel to the channel that normally fires the gun, and then assign the slaved channel to an unassigned switch.

But i can't get that to work properly.
If the VRa/b is not possible, is it possible to make a speedfire button as described here:
<<Quick and dirty method is to open the radio case, identify the three pots on the channel used to fire the gun, and short the up/down pot to the center pot to make the gun fire. Then solder in a wire and run it to a momentary switch of your choosing.

However, i see 4 wires coming from the potmeter not three.
Any tips or ideas?
Regards,
Jan
