This picture shows RV7A left intake of the bottom half of the cowl. The prints show to install 3 platenuts spaced 1 1/8" and I have a hole spanner in the picture to show that proper spacing. If I evenly put the three platenuts on that flange the most aft would be fairly close to the starter ring gear.

Placing it aft of that starter ring gear leaves me with a small area of fiberglass and moving it forward of the gear pushes the paltenut spacing much closer than designed.

Between the cowl and the gear I would guess that there is a 7/8" space.

Did you space differently avoiding the possible gear and platenut interference?

Not sure if ever the motor would shake enough during start up or shut down to have the gear get close to the platenut.
You will want to hold off on that until you install the baffles and the FAB because you will most likely need to trim the fiberglass inlets a bit. I eliminated the 3rd screw (I'm not the only one). It is working great with just 2 per side. I also didn't want a screw that close to the ring gear.

P.S. It's pretty crazy how much the engine shakes on startup and shutdown.

Thumbs up Thanks Jereme

Many Thanks Jereme. Ahhh the baffles and the FAB are those things that could catch me in this area of that aft screw, not only the ring gear. It's always those details I seek so I could avoid the 1 step forward and 2 steps back.
