Hello Rob and Trevor

I had finished my panel planing for an RV-7A. It include a 2 screen solution from AFS 3400, one to display the engine and VP-X data and one as EFIS.

Now the question that came up, which system's shoud I buy?

Option 1:
EFIS System, 1x AF-3400EF EFIS 6.5" Display
Engine Monitor, AF-3400EM Engine Monitor 6.5" Display

Option 2:
EFIS + Engine Montor single screen system, AF-3400EE Single 6.5" Display
MFD — second slave screen only, AF-3400MFD MFD 6.5" Display

There will also be a AF-Pilot, a AFCU from "Bernie" and a VP-X in the panel.

There is a smal price difference, thats not the point, I want to know from you, which setup gives me a better, less loaded, less complicated system, more redundant panel?

You are the designer, I only see the screen from the front side, so any input is helpfull.

Thanks alot and kind regards,
