flyfree69 is absolutely correct. There is no "climbing problem", its merely an effect of the wing design. The Xtra Easy has a flat bottomed wing, a design which produces a ton of lift. The tradeoff is that the lift is tied in with the speed of the plane. The faster you go, the more lift it will produce, hence the perceived "climbing problem". What you might consider doing is trim the elevator at a comfortable speed, say somewhere between 2/3 and 3/4 throttle, and do most of your flying at that throttle position. After a bit of flying it won't become much of an issue. Good luck!
