michaelking42 Posted January 11, 2008 Posted January 11, 2008 Hi there, relative new guy here and starving student working on CFI...looking for a little help. I need a couple of these adapters that convert GA headsets with dual leads to helicopter. Only trouble is they start out around $45 a pop, and that's for a dodgey one. So I want to draw on my skills as an electrician and build a couple of them (spares of anything are always handy!). I know they are not difficult to build, but I don't have any idea of the wiring configuration...perhaps there is a resourceful person out there who can direct me to the information I seek...I've googled and yahoo'd but I'm stuck at square one. I've attached a picture of what I'm trying to make. Help is always appreciated and reciprocated where possible. Thanks in advance... Mike Quote
nbit Posted January 11, 2008 Posted January 11, 2008 (edited) Would think you could trace the wires from a borrowed one with an ohm meter or get someone here to do it for you, then order the parts from Digi-Key. Should be cheap and effective. I have an adapter and an ohm meter, but not in a position to do it at the moment or I would myself. Maybe later if no other responses.

PhotoFlyer Posted January 11, 2008 Posted January 11, 2008 $35 from aircraft spruce, and they are good quality. Several of my students have them, havent had any problems in over a year. Quote
AngelFire_91 Posted January 11, 2008 Posted January 11, 2008 I took mine apart and traced with an Ohm meter for ya, hope this helps. Quote
Gomer Pylot Posted January 12, 2008 Posted January 12, 2008 Tip & 3 are mike, 2 & 4 are speakers. You can easily verify this with an ohmmeter. There is nothing tricky about it, just 2 wires for the mike and 2 wires for the audio. Quote

Witch Posted January 12, 2008 Posted January 12, 2008 I went and bought a replacement helicopter cord from sporty's, $36 I believe. It took a little work, but I got it stuck in there and it works beautifully. I think I still have a schematic and I can give you instructions. PM me if you would like more. Later Quote
