rwthompson67, Did you need to go with the Garmin back-up EFIS because the Dynan would not fit? I am about 3 months away from ordering my panel (SNF 2019 will decide) and torn between Garmin and Dynan for the PFD's. The Dynan (and MGL) are slightly wider than the Garmin and it's pretty tight in that space. One nice "feature" of using Dynan the AeroRocker switches will fit. I am pretty sure if using G3X I don't think the AR switches will fit under the display. Thanks
RV-14A QB building, Lycoming 390 Thunderbolt arrived July 2019, Garmin avionics, Vertical Power, EFII-32 Ignition and Fuel, hope to be flying Spring of 2020 !! Dues paid+ of course !!
