Hi Gary, I got to try it yesterday in slightly breezy conditions but I had the weight too far back and in the breeze it was really uncontrollable.I went back home and moved the battery forward but it had got just too windy for another try.Today was no better wind wise so it is now a matter of waiting for a good day for my next try.

Let you know how it goes


John

AG3-2-40 Still Airworthy

I took advantage of some light breezes and had some fun with the old (2 years +) autogyro recently. This flight was on a 2S 460 pack and was a relaxing good time.

Gary joined the Kansas flyers at E-Fly this weekend. One of the many great planes he brought was his AG3-2-40. After many wonderful demonstrations flying indoor,(including some loops!) it was time for lights out flying. Gary had installed lights on the autogyro. What was really cool was the light in the rotor blade tip. When flying by it created some unusual illusions. It was also very cool to see the blade tracking by following the path of the light. In day light the rotor looks like it creates a symmetric disk, but in the dark the light clearly demonstrated the non-circular path of the blades that would change a little in response to control inputs. I wish I had been able to get some video. Nice job Gary! It was an honor to meet you and it was great fun to fly with you in person.

We were able to shut off the lights Sunday morning and let SR71 show off his copter and flying skills in the dark. Cool.

5mm in front of the rotor shaft is correct. I think I'll try at the shaft next time, as it seems a tad nose heavy.

Hub

Able,

The only wood on the hub is above the top Depron disc, and below the bottom Depron disc. The wood prevents the rotor tube (which spins around the fixed rotor shaft) from pulling through the Depron. The 45mm x 20mm center block is scrap Depron to fill the space between the blades, and provide more gluing area. See attached from Willem's great drawings.
