I'm planning on a 4 point seat belt system for my RV-9A. I have no intention of flying upside down, so I thought 4 point would be better for pilot and passenger.
My friend says he has heard of significant problems with the shoulder harness pulling the lap belt out of place when you tighten it down. He says it makes the lap belt ride on your stomach instead of low across your lap.
Are folks normally using 4 point or 5 point belts in the 9?
