It is great to hear about someone else building and flying the Puppeteer. I really like the way mine fly’s. I have an OS.70 fourstroke and will admit it is more than needed. I think my justification was if I have to add nose weight (which you do) it might as well be an engine I already owned. It will also turn a scale looking prop. It really is a floater. I also spent a lot of time adding scale details to make it look like a Pup. A lot of the changes I made are described in earlier threads. I get lots of compliments at our scale warbird meets. It just comes in the minimum size allowed with its 60" span.
