I just talked to Bill O in June when he was in Iowa for a fun fly . He didnt mention anything about any problems or stopping his business, this concerns me a little . Any way i do have a NIB TS 52 with all papers and receipts. I have only picked the motor up to look at it and put it back in the box. I was planning on putting this on a Texas Hurricane this winter< now i want a Kange Monocoupe . I am thinking of selling the motor if your interested still havent made my mind up. Would be asking just what i paid for it $560. 00 I had to wait 3 months for mine from the time i ordered it last winter. If interested contact me .
