RE: First-time kit to build?
One of the best things about the Somethin Extra is the flight envelope. If you have your control rates down it makes an excellent second plane, third plane, etc. We have quite a few in my club and a lot of people agree they would make good first trainer planes. They have a stable, predictable landing characteristic. If you turn up your rates, it becomes even more fun to fly. A few people practice pattern with theirs. To me, it is a real do-anything kind of kit.
Also, it is one of those kits that begs to be modified. You may find yourself building a couple of them. I was given one and I modified some of it when repairing the crash damage. I still want to get my own kit and build it.
