I am in the beginning stages of wiring my 9A. I have electric elevator trim. Is it important to install the panel mount trim indicator? I have not seen them on the panel pics that I have seen. Maybe I just missed them.
Thanks for the input
 
Yes I'd say it's important!

If you saw my panel you didn't see them. That's because I'm using the Dynon EMS D-120 for the trim indicator. Works great....
 
On the EFIS/EMS?

In my case, I am not putting it in because it can be displayed on my Dynon system.

I can tell you that the Ray Allen LED indicator is hard to impossible to see on a sunny day.

You need something to get you close to the correct takeoff position.....
