Seem the best way to get a Kadet Sr. are

1) Built it yourself
2) Find one for sale. this is the way I got mines
3) Wait for Tower or the Local to get them from Sig.
4) Buy the Super Frontier Sr from( World models)
this seems to be a knock off of the Sr and i have seem a lots of post on them on the net.

** The SR was the 1st plane that I was able to fly with a buddy box and I loved it. its flys so stable.
