I only hovered the plane once for 5-10 seconds because it was the first time up for that engine, and I wanted to see how the pull-out was with the Vess 19A. If I went to a Vess 19B it would load the engine slightly more, but I wonder if the thrust for pull-out would be equal, more, or less? Had decent pull-out, but nothing to write home about.

Anyone else tried these props with a plane around 12-13 lbs.?
