You're welcome, are you building anything yet?

Gary,

Thanks, I've tested the blades and had fun, I'm just getting the video done, I'll be back soon.

Antonio, no I am not building yet. Still waiting on the CF for the rotors and shaft. I have been replacing sheet rock in my basement the last couple of days after replacing the leaky hot water tank.

However, after doing some more autogyro surfing, I do wonder why as a first autogyro that you don't see a stiff rotor with the coning built in like in this video. Gary, again I don't want to take away from your thread either so it my be better to ask this in a new thread.

Thanks,

That is some great video, never seen it before, I have sent him a message in Spanish hoping he'll get back to me with more info.

A coaxial rotor like that could be fun too TJ, it looks pretty stable and simple to make, I might put it in my "to try" list.

Here is a pic of my micro gyro with some coning built(bent) in.

New Photos


After a few days fighting that bully Flu bug, I was able to go out and enjoy some almost-calm weather this evening. Decided to take still shots for a change of pace. Still having too much fun.

Wow, Beautiful shots Gary!!

Love the ones with the orange tone sunlight!

Nice, Yours flies with the fusselage almost horizontal, unlike mine,

I think it's because you have more aft tilt on the rotor, it's a two blade, and your blades flex a bit more than mine, I used 10 degrees only, I must try one day.


I don't mind it that much because it comes to land already "flared" nose up!

I believe it has to do with Asymetrical Lift. (due to the stiffness of blades and hub)

You got that one pretty well sorted out Gary!

Antonio.

Auditorium Autogyro


I snuck off to the dark auditorium during our SPEF fly-in last weekend. What fun! The room is almost as big as a single-court gymnasium. It has a stage at one end, and sloped bleachers on both sides.

There's a good crash at the end of the video. My battery dumped as I was about to climb over the bleachers.

Nice one Gary!!

I'm glad it didn't brake

Same thing happened to me while hovering with a foamy at the park..batt went flat ...it fell down vertically from 2m, just a small crack on the Depron elevator's moving part!

New Rotor 40 Inches Diameter


I wanted to test a larger rotor on my AG3-2, so I had to decrease the rear tilt of the shaft in order to clear the tail feathers. This is a 40-inch two blade rotor made the same way as the smaller ones with 3mm Depron and a 2mm carbon rod on the leading edge.

What a difference! This is going to be a blast indoors! I have some balancing and tracking work to do first, though. You'll see in the video...

Hi Gary,

Beautifully stable flight and you managed a really short landing in what looked like still conditions.

Are you still using 3mm depron blades with a 2mm CF L/E?

Once you have balanced out the shakes it will be a dream!

Best wishes,

John
