Additional deciding factor, for those of us having exhaust pipe ends inside the cowl, how much of a clearance do we need in-between these pipe ends and the trailing edge of the cowling?.. 🤔
I took measurements at three Long-EZ's here on the field, here are the numbers:
Plane 1: Prop-to-cowling: 5.50"; pipe-to-cowling: 1.50".
Plane 2: Prop-to-cowling: 5.75"; pipe-to-cowling: 1.00".
Plane 3: Prop-to-cowling: 3.00"; pipe-to-cowling: 3.00".
