I don't own a H9 Ultimate, I have owned quite a few 40%ers though. On the subject of weight and engine choice, I am in the minority. I have had planes ranging from 38 to 45 pounds dry. 40 pounds and up would have to get a 200-210 for me to be happy with the performance. A 38 pound plane with a 150 is just about the right amount of over power for me, but 36-35 pounds would be better. I'm flying a 44 pound Extra right now and the performance is just too sluggish for me in the 3D flying. I have a 38% Columbo Anderson on the bench that will hopefully come in around 36-38 lbs, and a 40% Edge coming that should be about the same. Both of these planes have a smaller ~118" WS, and a fuse length ~108-110" which is smaller than some of the larger 40-42%ers out there.

There are quite a few large 40-42% ARFs out there that wouldn't interest me with a 150, they would have to get a 210.

I'm sure that 95% of the people that fly 40%ers will disagree with me, but I'm just spoiled when it comes to power.
