I currently have 2 YS110's and love them. I am looking at bigger planes that require a 140, I know about the 140 Sport but I have come across a 140FZ new in the box for a good price. Can you please tell me about this engine. I know YS no longer makes it and I am wondering why, I am assuming it is the same as my 110 internally but punched out to 1.4. Would you recommend it or should I just buy the Sport?
