Has anybody ever done a piece to camera in a helicopter before as i have one to do and was wondering if you can plug into the internal system or do you just use a certain mic to do the job with ... any ideas most welcome.
 
I would think that the best you could hope for is to get decent enough audio to be used as a guide track for ADR later. Unless you want really realistic audio as to what the inside of a helicopter sounds like, you will be much better off replacing the audio later.
 
You can usually tie in to the system in order to get audio from the headsets/mics. Then again, I fly in a news helicopter, so we have it wired this way. I'm not sure whether other helicopter comm systems are wired with an output. The pilot should know what the capability is.

ADR is probably easier in this scenario. I'm not sure if it's easy to get that "Radio/distorted" sound as if they're talking over the headsets. It may be some really easy effect you could put on it. If not, you could try using two phones in your house. Talk into one, and record the sound from the other in a different room. Hope that helps.


EDIT: As for your mic question, we use Sony ECM-66B's lavs attached to our headset mic (plugged into the system) for live voiceover. The sound is obviously from a helicopter, but sounds like a phoner on the air.

I've always just placed a lav inside of the earcup of the headset...

It's quite enough to knock down the worst of the chopper noise, and allows fairly good conversation to be recorded... you can also clearly hear aircraft to ground, if need be.

The drawback is that communication system must be "keyed" by whom ever is talking. In a helicopter, that is usually a button on the floor of the aircraft.
 
Thanks for the repys guys i think ill go along with the ADR way to keep quality
its nice to know no matter what questions you have there is allways someone who has been there before or has the know how to help people out

thanks again.

fixed wing uses two cables, one for mic and one for the headphone, rotary wing (helicopters) use one single cable for both.

there is a cable adaptor out there that does both.

tying into the intercom would be your best bet.

i normally tie into the intercom and run another mic to get the ambient noise.

the trew adaptor is great but it is meant for fixed wing.

i have very little helicopter time but i'm sure you could figure out an adaptor to make the trew cable fit a helicopter.

trew may even have the answer i'd give them a call.
