There is more to reading than just reading. There is a comprehension factor in play here. The plane has enough power, and probably does not have a fuel problem because the engine flys and does not dead-stick. The prop is probably just fine. There is a recommended prop range and you are in that range. The OS .55 AX flys a Goldberg Protege around just fine (read Mike's review of that plane) and would fly my Goldberg Skylark 70 around but I had the .75 so I put that on the plane, and it flys just fine, never needing full throttle for more than verticals.

As Ken was trying to suggest, get back to basics and learn to fly on the wing. Be satisfied with the performance of the plane because that's what it does. If you want a rocket ship on take off, get something that will do just that and fly it. Hand launch it if you wish, that way there will be absolutlely no runway runup prior to lift off. But that will take a lot of power.. and here we go again.. Going balistic is not flying. That's what rockets and bullets do, with a lot of rocket fuel or gunpowder.
