If the idea of building appeals to you, and you want a Plane that you can put your own stamp on, then I would say try the kit. You won't have much trouble, and if you hit a few snags along the way there are plenty of threads here on RCU regarding the 4 star. The final result will be a Plane that you can say you built yourself, and sure joy when you see your self built Plane take to the sky, and fly great!

If the idea of building does not sound like your cup of tea, or you have very limited free time, then Sig makes some very nice ARF's, and you will be happy with how nice of job Sig has done building a 4 star for you. Either way you go, I would say you are sure to enjoy!
