i have used a 808 keychain camera for the audio and put t together with the fpv video... i am still waiting for a micro vtx with audio! but this is a nice solution.. but its a little work to do...but fpv video with audio is much better for the fpv experience!! enjoy it, share it... subscribe to my channel... there are a lot of video's yet but more in the future... car fpv, racequadcopter, microquadcopter...or fpv flying with my Easystar 2 plane that is a real flying experience. its all my favorite...i love rc and fpv!
