Hello, I have a friend who has a 1940 tango gyro plane. I have searched high and low for one on the internet with no success except yours. The one he has is a bit different. Do you know where I can find information on it or a web site? His R/C gyro is huge compared to what I have seen here. It is vintage i know that much. He was thinking of putting it on E-bay but I can not find even a worth to start an auction. Thank you if you have any information that can assist me.
