years ago someone came out with a .40 size rc ringmaster kit but cannot remember who though. at our flying site some other flyers told us about it that the local HS just got one in. myself and a buddy went to check it out. the picture on the box was deceiving. we opened the kit and looked at the plans and the they had made it a high wing trainer type plane!. even the owner of the shop was surprised at this too. but they were not manufacutred very long because it turned out they were not good sellers
