Alot of people mount theres up on top of there helmets, I am tried that and dont really like it, Im not 7 feet tall so looking at my video as if I was looks goofy. plus I like to here the beeps to know what I am doing with the cam or even see the front screen. Heres the two that I have used the most.
I really liked this spot because it gives you a really good view of everyone else. always looking right where you are and I could flip it up to see the front screen. Big issue though is that it pulls down the front of your helmet over you eyes so you are constantly pushing it back up.
Here is my new setup, I have used it twice and love it. Perfect view angle, close enough to here the camera beeps, and doesnt pull my helmet down at all. I cant even hardly tell its there. it looks like it is kinda in your face but you dont even see it without looking way up. Also make sure you have some sort of lanyard to catch it if it falls off. you can see I have a stainless one running off it.
I left the other mount on since Im still trying this that way if the glue doesnt hold and it falls, I will just stick it on the other mount (mechanically attached) and keep riding.
