The Sig Kadet MK II is a very easy, quick build. It's also a very good trainer flyer.
You assemble the fuselage sides right on the printed side sheets, which are clearly market for locations of all the bits and pieces.
Several years ago, a friend told me that he and several of his fellow flyers would build these planes in a weekend and use them for simple racing. The simplicity, quickness and ruggedness of the build are what inspirded them.
Equally inspired, or challenged, when the time came to buld a trainer for another firend, I chose the Kadet MK II and took up the weekend building challenge, Started on a Fiday evening. By Sunday, it was done. Given my fanatic building style, where everything must fit perfectly or be adjusted, that was quite a pleasant surprise.
Now, some 20 years later, I've started using that plane with total success. Never cashed or hard landed. Still as good as the day it was built.
You should enjoy both the build and the finished plane.
