Just did a quick look for the equalizer board and it says it has a solenoid.
Solder the wires for the RF, onto the 2 wires that go to the solenoid (1 on each wire)
Doesn't matter which way round the wires go.
Good thinking but afraid not-don't think the A5's pig iron internals would be too happy doing all that speedy stuff! (And yes I do realise how Iropnic that is bearing in mind that I am planning on using one of the fastest loaders in the world)
My project is a SAW machinegun style ammo box kind of in the same vain as Oily from Walkonzone (I point out now that it will almost certainly be nothing on his as my skills are slightly more limited.....but worth a bash)
