Jason.... Dynaflight used to make a Cessna Trainer .40, you could consider that (if you want one and can't find it -- it is out of production -- let me know). It's a kit... were you planning to build your own plane?

You know if you're cracking up trainers pretty fast, it may be that your current instructor doesn't really know what he's doing... I'd highly suggest getting a new one.

Now, if you're planning to build your plane, you can always make a generic trainer look like something else by "kit bashing"... take any shoulder wing trainer, raise the wing a couple of inches (being careful to not change the wing's incidence angle), add a turtle deck if needed, reshape the tail (being careful not to change any angles or areas) and you can create all kinds of scale planes and still be assured that it'll fly like a trainer. With the rubber powered planes you've already built, I'd recommend a kit bashing project just to get familiar with tdesign and building practices for an r/c sized plane, then you should be ready for scratch building. At that point, the Ugly Stik is a great first scratch building project.
