I am making some progress on the DVR mod for my EV800 goggles. Here are some pics of mock up and fabrication of the buttons. I used some arcade button switches I had laying around.
Here is my first video post. No sound, and sorry the reception is bad, I am still looking for a good place to put the DVR goggles. This is one battery pack, edited out the crash retrieval only (and one battery wire repair).
It wasn't too bad really, there were already instructions on YouTube. It was a one day project, probably took about 4 hours. I would recommend this mod to anyone who likes to tinker.
I modded it mine and it works great. Love the concept. Just make sure you don't fly in the AV mode since it does have a slight delay to the live feed. I always fly on the live feed channel.
