Q: Does this microphone have flat-tip screws or allen screws to secure the connection?
A: The screws will use a flat head screwdriver. There is an additional screw that will need a Philips screwdriver. No allen wrench is needed.
Q: Will this mic work on the David Clark H-10-30?
A: Yes, the M-7/DC microphone can be used on the David Clark H10-30 Headset. However, you will need to get the David Clark M-7/DC Amplified Electret Mic Retrofit Kit. The retrofit kit will be required because it comes with the mic cord you will need. The M-1/DC on the H10-30 that you're removing is hard wired and therefore you will need the new cord included in the kit when attaching the M-7/DC.
Q: I would like a David clark microphone (electret and amplified) to work on H10-76, that can be used on Cessna 172. I have the "Y" cord, but not the microphone. I already have the M-87 dynamic. will the M-7A work better?
A: In order to use the H10-76 in a civilian aircraft, you would need the 1142-22 microphone.
Q: Will this mic direct replace the m-4 on a H10-40?
A: Yes it will.
