Nextar, consider replacing the wheels on the mains. I've got the same problem, and took a close look at it. The Tower Trainer comes with 2 3/4" wheels (all three). It definitely sits nose high/tail low, even with the nose gear mounted up as far as it will go. I have a set of wheels from an old airplane that are 3 1/4 that I'm going to put on the mains, and tweak (bend) the main gear so that I can get a stance that is level and not looking like a taildragger that you describe. Good observation on your part, I'm surprised I missed it. If you are going out to buy larger wheels, I might suggest you even look at some foam 3 1/2". I'm sure this positively affects the taxiing ability. Good call Nextar. It's obvious the people who put these together for Tower aren't up to speed about this problem. But that's not too unusual. It's not uncommon to swap out wheels for something more appropriate on an ARF. I fly off of grass, and larger wheels are always a better idea. Just don't go too large, nose low is bad, the plane wants to stay on the ground with that kind of configuration. Good call Nextar. Thanks for pointing it out.
