I'm sure there are. I'm not an engineer but my opinion is very affordable. The plans place the thrust line basically in line with the top longeron as others have stated. Do you plan on making major changes from the plan or why do you ask? Moving the thrust line considerably above or below that line could / will cause greater pitch changes with power changes when compared to a top longeron thrust line. Few aircraft designs place the thrust line low because of prop ground clearance but many have a very high thrust line like the Kolb, challenger, and others. These designs are quite flyable but the pilot must be aware and respond to major pitch changes with power changes. An inch or two above or below the top longeron in a KR would probably have little noticeable effect with power changes but, like I said, I'm not an engineer. And like I said, my opinion is affordable. It cost you nothing at all. :-) Larry Flesner
