I agree with Rock. We had one of these show up at our training sessions after having seen one in the hands of an experienced flier. The first one, with the capable flier was less than impressive. When we finally flew the newbies it was quite a handful. We had a buddy cord but were afraid to hit the switch. It ran out of fuel early (we thougth--don't know what size tank) and learned that it glides like a brick. The guy flying it basically pointed it at the ground and we walked a long way to pick it up. Finally bit the dust a few weeks later at some other field. Lesson learned was to call the LHS that is selling and attempt to have the owner dissuade anyone from buying as a trainer. The experience flier eventually put a larger engine in his and it looked a lot better.
