The LT-40 is a great trainer; so is the LT-25, by the way. They both tend to climb under power, it's part of the characteristics of a flat bottom wing. You can reduce the wing incidence, but it's not that big a deal once you're used to it. They both land great if you bring it in slow enough. I almost prefer the LT-25 for its light weight and easy transportability, also an easily built kit.
