RE: guillows wings
If the wing is a scale cross-section it'll probably generate lift. You may have to do some considerable lightening and re-engineering to make the Guillow PBY flyable. My understanding is that it was designed as a display model so it was designed for scale fidelity rather than fliability. You can probably substitute lighter wood, remove some of the longerons, etc to get the weight down. It's likely too that you'll need to slightly enlarge the vertical and horizontal stabs to make the plane stable and controllable. Good luck with your project!

RE: My electric autogyro flies!
I'd love to reproduce it. I'm just getting my biplane flying wing ready for test so I'm looking for a new projectile...er, project.

RE: autogyro research
Interesting projects on your site! I don't know how far you'll get desigining your own 'Gyro for the project but in the post here: http://www.rcuniverse.com/forum/My_electric_autogyro_flies%21/m_2325673/tm.htm the author seems to have avoided a lot of common gyro problems by using a helicopter rotor head with appropriate controls. Don't know how big model helos get but using off-the-shelf parts could save you a heap of trouble.

RE: My electric autogyro flies!
Great work! Using the helo parts seems to have moved you right past a lot of the problems folks find with gyros. Thank you for providing the detail on what works and what doesn't.

RE: My Shiney New Kirara Gyrocopter
Thank you for the excellent reporting! Too bad about losing the wheel but your thorough review of the plane will make it certain that the rest of us will replace the cheesy hardware bits as a part of the assembly process.

RE: My new FA-61
Ha! I'm still so far down the learning curve for autogyros that if you told me the heads were blabbering I'd Google on "rotors + blabbering" [:D]

RE: LASER CUT MINNIE !!!!
Nice work, Wahid, but I'm not familiar with the Minnie. Could you please point me to some further information about it?

RE: My Shiney New Kirara Gyrocopter
Ditto: any unusual problems or head scratchers? I believe that the Kirara is supposed to be an ARF but that word "Almost" can cover a lot of territory.[8|]

RE: My new FA-61
Fine looking gyro - and a Wankel engine to boot! Guess you won't have any problems picking your plane out of the crowd at your local field! Great photos as well. Have you encountered anything out of the ordinary in building the FA-61?

RE: Twin head Autogyro help
Can't pin the design yet - but then I don't yet have all of the plans I ordered either. As for the heads, I'd fab new ones with the same size blades, angle of incidence on the blade, etc. as your current setup and use two 4-40 nylon screws through each blade to hold it in place. You can find the screws by Googling on "nylon screw." Why nylon? It will likely shear in the event of a blade strike which will minimize damage to the aircraft. I'd love to take the credit for this one but I believe that it's a feature of Autogyro of Arizona ( http://www.autogyro-rc.com/default.asp ) kits. As far as not flying, I'm guessing that you mean the flat plate blades. Another peculiarity of twin heads is that they work with flat blades. - Just don't forget to balance each of your new rotor assemblies.

RE: Twin head Autogyro help
I am thrashing together an electric twin rotor. When I started I had a vague idea of how the things worked so I did some research. The best site, although it's currently not being maintained, for model autogyro stuff is: http://www.autogyro.com/ Read everything at the site, follow the links there, and you'll go forward with a lot more practical knowledge. For a very good article on how 'Gyros work try: http://www.jefflewis.net/autogyros.html For ready-made rotor blades: http://aerobalsa.com/ Basically, teeter and flapping are both ways of dealing with the retreating blade problem that affects all rotorcraft. A blade advancing into the airstream develops more lift than a blade retreating with the airstream. So one side (retreating) of your rotor disk is developing less lift than the other causing the 'Gyro to roll toward the retreating blade side. Visualize an airplane with one long wing and one short one. By allowing the blades to teeter or flap the effect on roll is minimized. Teetering is where the rotors on a two-blade head are coupled together and actually teeter up and down on a pivot point at the rotor head. Flapping is the use (In models) of a flexible plastic mount for the rotors. They both do the same thing but flapping allows the use of three or four blade rotors. The good news for you is that twin rotor designs don't suffer from this handling problem because the roll tendencies are cancelled out by the oppositely rotating rotor heads. Hope this helps.

RE: Twin Rotor Plans?
Thanks for the encouragement and the pix, Dickeybird. When I raised the idea of a 'Gyro at my local field the reaction ran from "You're crazy!" to "Why would you want one of those?" I'll order the plans and build a Spin Doctor. Revenge is sweet - and non-fattening!

RE: Twin Rotor Plans?
Thanks for the help! I scoured Bob Holman's site but could not find the Gyrace so I emailed him. A few hours of scouring the 'Net also yielded the Spin Doctor (Photo below) from the "Flying Models" magazine online plan service. For any who are interested http://www.flying-models.com/ is the site. Their site doesn't allow linking directly to the desired page so you have to click Plans Directory and then go to page seventeen of the listings. Should be fairly easy to scale one of these down to Parkflyer size. I'd still appreciate hearing about any other plans source for two rotor gyros.

Twin Rotor Plans?
[font="Verdana"][/font] This is my first post. I am interested in building an electric powered, twin rotor R/C autogyro. After reading all of the posts I went to autogyro.com - they are not processing plans anymore. So I did lookups on Gyrace, Kestrel, etc. -No joy. I am a long time Free Flighter who's switched to R/C electric. Balsa, foam, carbon rod and rag construction are all fine with me. I can scale plans as needed. Could anyone provide me with a source of plans for a twin-rotor? I know that real men fly single rotor but I'd like to make things as easy as possible. Thanks!
