@@Mr.Speedcat seriously!, it would take an electronic whizzzz kid to do that, and it could only be done with the Thunderbolt 1003, which has relays for the "hi-lo" fire call. (That is, if you can find one in working condition. A real one, not a computer generated one!) Ohhh, and a FS 3T22H might also be able to do that. (Also only a real one!)
