Ok, new question...
I bit the bullet and bought an A20. I have every intention of recording both my training, and a number of subsequent flights. Accordingly, I've also ordered a GoPro, and a Sony Digital Voice Recorder.
The question is relatively simple, but I suspect the solution is very, very complicated: how can I Y-Split a U174 jack into another U174 jack (for the aircraft) and a 3.5mm jack (for the Sony)?
Answers on a postcard!
