I was just reading the article in the new Kitplanes about the CH-750 (nice article). And I had two questions. 1. The picture on lower left of page 14 shows a BIG tab on the outboard end of the right Flaperon. What is it? And what does it do? Is this a trim tab? I looked at every other photo I could find of the CH-750 and I could not find a picture of the left outboard Flaperon to see if there is a BIG tab on that Flaperon too. Any help here would be appreciated. 2. After reading the posted specs for the CH-750 in the article and from Zenith, I have this question. If the CH750 is bigger, longer wing, wider cabin, wider horizontal stabilizer and elevator, heaver and still has the same 100HP as the 701, how can it have a cruse of 100MPH @ 75% power? The 701 is smaller, lighter and has the same 100HP and it only has a cruse of 80MPH @ 75% power. Why the difference? I know I should ask Zenith this question and maybe they will see this post and answer it to help us all. But if not I would be interested in what the group might offer.

Since the struts on the 750 are airfoils, this improper installation necessitated the trim tab on the right wing balance things out. Apparently, the streamlined struts contribute quite a bit to an increased cruise. Another contributing factor to increased speed would be choice of propellers.
