RE: RC Autogyro in Spain back up

I used Babelfish for translating the page. Ok, it writes nonsense often, but it makes it page more understandable for those who don't understand any spanish.

RE: Tandem autogyro

Steve,

The reason I asked the height difference is the turbulence from the first rotor to the second one. This turbulence has a negative effect on the sesond rotors lift with high angles of...

RE: Tandem autogyro

Are the rotors supposed to rotate to same or different direction in tandem configuration?
How much there should be height different between the rotors?
Are both rotors supposed to move to...

RE: Why do you fly autogyros?

Hi, Phil!

That is me flying both autogyros on the video. It is not a matter of flying skills or well flying machines. It is a matter of video editing. I can choose the clips I want to my video...

RE: Why do you fly autogyros?

Oh yes, there is still one thing that has inspired me into autogyros. It is an old PC game called Crimson Skies. There were air pirates and autogyros in the game. I thought they were cool [8D]:D Some...

RE: Autogyros Over Spring Hill Videos

Thanks for the videos Frank. I have been waiting for these :) It's too far for me to come to Spring Hill just for Autogyros ;)

Interesting to see many different gyros on the video.

Dual rotor design questions

Hi,

I am going to try dual rotor configuration on GWS E-starter or my G400 autoryro. So far I have built only single rotor autogyros, so I wanted to try something new.

My idea is to use...

RE: prerotator

A rubberband that twists around the mast and falls off after it doesn't have any tension ? :D That would be one cheap and simple way to do it. If that is not your solution for the pre rotation,...

RE: prerotator

The weather is here getting wet already. I still hope to have ice on the river for next 4 weeks so I can fly my models there. Here is a picture from my backyard today how does it look.

RE: prerotator

I am also interested about the free wheel issue? The electric motor slows the rotor down without free wheel.

I have sometimes thought a brake for the rotor would be more useful than prerotator....

RE: Why do you fly autogyros?

Hehee,

I find myself from your story :) We do these things because it is chanllenging, not because it is easy. The wind problem is also familiar. Much wind is not good for autogyros because it...

Why do you fly autogyros?

I have thought why I like to build and fly autogyros. What is the thing that makes you build and fly these machines?

Here are some reasons, why I do this:

RE: G400 autogyro

Hi, Phil. Your idea about moving servos behind the pivot point is great idea. I will try that one on next version I will build. I am too lazy to move servos now, when everything is working fine. The...

RE: G400 autogyro

It is interesting to see others having problems with autogyros as well and how they have solved the problems. I solved my problems by using better pushrods to the mast and redusing the rotor angle...

RE: First autogyro flight

My first autogyro flight was a failure. This was probably due to my poor design and my bad autogyro flying skills. It flew forward for 20 meters and crashed to it's side. The second design was much...

RE: My electric autogyro flies!

This gyroplane inspires me greatly. I would want to build also something as simple as this but I'd like to build the head by myself. Is your gyro following the "CG just ahead of the main shaft axis"...

RE: Autogiro parkflyer

That looks good. You are true that there is a need for nicer looking autogyros. You also right that your model needs more blade clearance. A boom strike might occur during hard landing. It would be...

RE: Formation flying pictures

A strange formation with a Pico Stick and my .15 sized autogyro :D The rotor caused big turbulence for the Pico Stick. The pics are taken in North Finland in summer 2004.
