I totally agree,
I have built several C/L planes and the ringmaster is one of the best. It was the one I first learned on over 40 years ago and it was still flying until a year ago when I crashed it beyond repair. Since then I bought another one on EBay. It is still new in the box and still wrapped in plastic, never opened. If somoene doesn't come up with plans, I will go ahead and open it and copy the plans for you. Your cost will be the price of a copy and mailing.

PS: The kit I have is the Sterling models Ringmaster 35 Pro by Estes. By the picture on the box, it looks exactly like the older version S1 Sterling models had.
