Hello sirs: after talking to your forum members, and studying what I do not Know. I have found damage that will require someone who knows gyros. I have emails with an member and he mentioned perhaps an hard landing, however it does not seem to line up with an tape measure even if there had been that kind of force downward. There is inner rotor damage and prop tip damage but they don't seem to align. This gyro will need rotor blades and prop blades. It is an 447 air command, and from what I have seen runs on second or third pull. Every other aspect seems to be great and works as one would think it should. I am trying get pics up now to an album but will not load. I can email pics of gyro and damage Just trying to help you if you need it, and an friend at the same time not knowing much of anything except what I can find online. What is an running 447 engine and nose cone worth alone, much less the rest ? don't know.
