I only have the pics of the install of the 1090. I tested the plane with the 100 today. I tached the 100 after the first flight. It turned a PAU 27 3Db prop 6400 rpms, which is exactly what the 85 with the 1090 turned the same prop. The plane has considerably less vibration with the 100 as well. As far as flying goes, I have never felt more confortable with a giant scale plane. Against my better judgement, I was doing slow high alpha inverted passes on the second tank of a brand new engine. With the very little extra weight of the 100 the plane does not even feel it. It is a major floater and super stable. I would definately recommend the 100 on stock mufflers over the 85 on a pipe any day of the week. But of course, that is just my opinion so take it for what it is worth
