I had an Aircore trainer when they first came out. Thing flew like a brick with wings (fortunately tough as one too). Had a couple of instructor-led flights with it, then decided I was ready to head out on my own. First flight was fun, and uneventful. Did several takeoffs and landings, just to get practice. The engine wasn't very reliable (more likely the operators skill with the engine was lacking), so that made for several interesting challenges for a newbie. But, what great fun.
