Four Star 120 Question:


Moving the thrust line "Down" 3/4 inch to center the prop hub in the center of the 4.5 x 5.5 firewall.

What effect will this have on its flying characteristics?

I have attached a pic of it being done. Need room for a gasser. Would like to use a 7' Radial Cowl (generic) from Fiberglass Specialities. I believe it is the cowl in the picture.
