My first plane, many years ago, was a Sig. You can see a picture of it in my gallery. While it doesn't meet the specs for the typically recommended trainer today, or even then, it flew great. For reference, it was powered with an Enya .15, was only 3 channel, and as you can see in the pic, was a tail dragger. It was so much fun I recently convinced a fellow club member to part with one of two unopened kits he's been saving for years. Someday I will build another.
