Flying in a crowded airspace may be challenging I decided to build a system that would allow me to see behind.
I mounted a small convex mirror on the riser. Here is a pic of the riser mirror.
It simple attaches to the riser with a cable tie .
Put it on the d riser pointing back of course and it gives you a great view of what is behind you .
You can simply aim it in another direction if you want to see the other side or even put another on the other riser!
Works great ,try it .
