On my last ship, a Pilatus B-4, we had a PTT switch on the stick but only a
hand held radio.

We went to Toys R US, found the best sounding toy machine gun, ripped out the
innards, hooked up a 12V-6V power supply, and triggered it from the PTT.

What fun it was shooting down other sailplanes in thermals!
