I bought the Hero 7 I mounted it above the screen in my +8... Great vid quality but the sound of windrush drowned everything else out on the move. Bought a remote mic which required a block like interface, in size the block is a bit smaller than a matchbox. In order to accommodate the "matchbox" had to buy another mounting case into which the matchbox fitted. The remote mic is a pinky sized and omni directional type it cam with a small "sock" designed to cut down wind noise. The mic came with a about a 2 meter (6ft) cable, and allowed me to try it in a variety of positions, all of which were subjected to wind...!!!
Since then I have bought an extension lead for the mike to allow me to extend it close to the exhaust pipe end, but as yet I have not road tested it to see it if there is and improvement..
If you look in the vid section of the site you will find some vids with great sound that Mossy made, though I suspect his mike may be better than mine and with a larger sock/cat..
Good luck with your film making attempts... Enjoy..
