It's a 4 Star. Manufactured by Sig manufacturing. It comes in three sizes in kit form, .40, .60, and 1.20. It is available as an ARF in the .60 size.

It's an excellent low wing trainer in any of the sizes, and a good flyer in it's own right. It can be kit bashed to become almost anything you want to make into in the low wing format.

I have built 6 or 8 of them in various forms. They have all flew extremely well.
