Alright not looking to suppliment my income by becoming a top 10 Youtuber, but we have a vacation to Florida and some deep sea fishing coming up, and we want a go-pro. I want one I can mount in the 140 if I'm going to get one. I'm cheap by genetics... Not looking for the latest greatest but still solid decent unit. I still have my Iphone 6 and am still happy for reference. Here are my questions: I should get one with external mic capability right? So it can be wired into the intercom system of the plane? Hero 4 Silver Edition seems like a good candidate, yea/no? I fly a 2 seater, but my intercom is a Sigtronics SPA-400, 4 place intercom... So I'm assuming I can have the external mic wired to that so I don't have to mess with a splitter or whatnot from a headset jack correct?
