I had an OS91 in a Yellow Aircraft Extra 300 and it was a great combination. I just so happen to have a Yellow NIB Cap 232 for sale in the market ads right now... I can make you a nice deal, plus I'm in Florida so the shipping will be minimal. Also a perfect match for the 91. Check out
www.yellowaircraft.com in any event. Great stuff.
I apologize for the blatant commercialism. --Tony
