I have been out of this forum for weeks. So many tasks, so little time.

Here goes a few pictures. Some friends of mine built a gyroglyder. We played with it today. There is a picture of a motorized monoplace from another friend. I hope you enjoy.

that's very cool. Are those blades CURVED??? Camera shutter illusion, which I think it is. The blades are still spinning and so is the prop in the second picture...

I like that powered machine, do you have more info on it and any pics of it in flight?

Hi, how are you, Shawn? You are right, it's just a camera effect. It takes some time for the image to be scanned, from top to bottom. If an object is moving, it's appearance is distorted.

Timothy, yesterday I didn't take any pictures of it in flight. I was preparing the glyder when that AC-4 take off. You can see more pictures of the AC-4 here: Brazilian Gyros

Empty weight: 157 kg (345 pounds)
Max. weight on take-off: 290 kg (638 pounds)

Hi, Heron. These days I had been very busy. Not much time to enjoy things I like, one of those is Rotorcraft Forum. But I got very happy because whenever I am back, there is a huge amount of new threads and very interesting material from our fellows.
 
The airframe of that VW gyro is nicely designed. It badly needs a horizontal stabilizer, however.
