Mansoor,

Glad you got it sorted out.

Now, let's see some videos!

I have had a brass tube, cf, three 5g servos, 10A esc and a turnigy 2730 1300 earmarked for this. Maybe it is finally time to do one over the holiday.

Skysailor, Gary, might I interject an idea as to the right tilt. Since this is still a tractor type aircraft, the angle (thrust) of your motor might be causing your issues. You might need to adjust right thrust 2 or three degrees. From your picture it is hard to tell if you have any right thrust...

Gary is that plausible?

Tymbrewolf,

While right thrust would affect primarily the yaw axis, it might also help the roll due to coupling.

I have as near to zero right thrust on mine as I could determine, and the AG requires only very slight right tilt.

Only one way to find out!

Beautiful work SR71! How about a cooperative effort for a proper set of plans?

I would like to build one and would develop the plans anyhow.

Wow! That Old-Timer looks pretty good! But, I think you'd have to make the mast taller and the vertical stabilizer shorter (or split into two), so you might as well just draw one from scratch!

I don't have any plans. Never had any plans, and never will have any plans. So, be sure and post them for me when you draw them, OK?

Made two sketchup file from your photos. I guess I didn't realize how big this is...

Auto gyro side printed pages 9,10, 15,16,17
Autogyro top printed 5,14,22,23,24
Measured my printed paper. Appears to be within 1/16" in correct size.

Gary, do your blades butt up against each other on your two blade rotor or is there some (hub) material between them. Your photo in post 68 shows 12" but it doesn't go to the centerline, but instead to the outside of the ply top support. I am hoping to finally get started on mine over the holiday (six months after buying my CF, motor, and brass tube).

Also from the top does the right blade le tip up or the left blade of the rotor's LE tip up?

The blades do not meet at the center. They stop about where the line is in the photo in post 68, near the edge of the ply. The carbon LEs extend to the adjacent blade, so I have more gluing area. There is a piece of scrap blade material between the blades. The LEs of both blades are angled down a few degrees so the air coming up from the bottom will rotate them. The rotor rotates clockwise when viewed from above because I'm right-handed, and it's easier for me to spin it that way. Clear as mud?

Plans ready.

Ok Gary,
I have decided.!!!!
I have made DXF plans from your photos.
They are almost to scale (warping from the camera).
I do waterjet, laser and router cutting for a living.

So here is what I decided..
I am not going to build it.
I am going to buy yours.
Quote me with shipping to South Africa please.

Peter.

My grandson is driving me crazy!!!

Hi all,

While reading through this thread I became very impressed with Gary's wonderful autogyro design. Needless to say, I just had to build one.
Since I like building along some form of plan, I got in contact with Gary and we decided I'd try and do some drawings. So, here they are. I've printed them into PDF, and there are tiled versions for different paper formats. All in one zipped package.
Have fun and happy flying!

Willem

(in the mean time my gyro is waiting for the maiden flight, a little too windy for it right now, here in Holland ).

Drawings

Willem,

Fantastic drawings!! I hope everyone enjoys them. Many thanks to you. Here's hoping you get some calm air!

Peter,

My AG3 is getting rather beat-up, so I suggest you build your own using the wonderful drawings Willem has posted.

Happy flying to all!

Gary
