I had worked part time for Chris Machin (Progress Manufacturing making Rev-Up props) back in the '70's, and he spent a considerable amount of time on the phone talking to other old time manufacturers like Axelrod (Top Flite), Goldberg, and K&B (Brodbeck). His Rev-Up line of props was started in 1949.
The Mig-27 drone foam airframe was made by Goldberg models, powered by K&B, propped by Rev-Up. It was known as the FQM-117 target drone. In this photo the prop has the classic Rev-Up shape, and the K&b .65
Thanks for posting that. Thats pretty neat! These engines are definitely unique and have a useful purpose, and sometime I'd like to put one in an airframe and fly it... I have other priorities, so replacing the carb wont happen for awhile. I'd like to think they have the torque to turn a 15" prop, but I doubt I'll ever try it unless I borrow a prop from someone.
