Gallery: Auto-Gyros of the Past, From the PopSci Archives

1 Comment

When you looked in the back of the Popular Science magazine in the nineteen-sixties and beyond, there were adds selling instructions for home built gyro-copters. They were supposed to be easy to fly and didn't require a pilot license. Some people actually built them and they did fly. But, it was a little more than an open frame with a pusher prop and a large, free wheeling rotor on top. They could fly very slowly and land almost straight down.

They could also fly into pieces and fall from the sky like a rock since they didn't have wings. The rotor had to tolerate quite a bit of strain.
