Hi many thanks for presenting this Gyro. Very inspiring!
Had to build one myself, based on the info presented, see result below (Pitcairn PA36).
Unfortunatelly flight characterisitcs have not been that great so far. Flies nice right turns but tends to fall into left turns. Starts are also risky, have rather strong right trimm in flight but have to hold to left during starts, otherwise it will roll to the right during start.
I guess I will have to play with roll trimming and motor angles.
Anyway, I loved building.

Hi Werner
Very nice this is one of the models (Pitcairn PA36).I have on my list that I would like to build
Do you have any build photos or any flying video I would like to see how you made it

Hi Joe,
I had it on my List for about 7 years before it came to be. It is a simple silhouette model covered up by a casing made by deep drawing selitron over a positiv mold. Silhouette is taken from the only good sideview photo of the PA36. Top and front view has to be deduced from other fotos of different angles. Have a look at "criticalpast", there are videos of the original and still fotos. I have only flying videos of the silhouette model without casing ( and these are not good). I had no chance to fly it with casing so far, sh.... weather here in Germany.

Many thanks for the info
I did think it was molded I can see the tape holding the two halves together
I look forward to seeing your progress
You are best to start your own thread rather than posting here
Awe the best Joe

Message for Mintie (Graeme)

Hi Gang, This message is for Mintie (Graeme). I am building the AG3-2-40 autogyro, and was wondering what diameter spring steel wire you are using for the landing gear ?? Thanks for your help. Charlie Anderson (ottogiro58)

Hi Gang, OK, much thanks to Mintie for the LG music wire specs. I am a noobie to electric models and need some information about charging /duration of the 2S 450mAh Lipo battery. How much flight time can I expect from a fully charged battery ?? I am running a Park 300 brushless outrunner (1380KV) and 9 x 4.7 Slow Fly prop. This model weighs in at 8 oz. I want to break in the battery properly, so this duration info would help. Also, any pics of the initial rotor tilt would be great. My version sports a fixed 40" two-bladed rotor head, dihedralled tailplane, and rudder/elevator/throttle control. I have the rotor head tilted slightly to the right to compensate for motor torque. The weather will be better in a couple of days for its test flight. Some much needed rain is heading this way. I will post pix soon. Thanks for any and all help. Charlie ottogiro58@aol.com

Hi Gang, I'd like to thank Gary (sr71afan) for sending some helpful pix and information. You guys are great !!! Pictures of the new machine have been posted. The transmitter is on charge, and I am looking forward to some serious air time tomorrow morning. It will be great if the 3-channel control works well. I am hoping for a real floater !!! Talk soon !!! Charlie Anderson

Hi Gang, I did some test flying this morning of the new 3-channel autogyro and although I managed several flights, the machine would not climb well, even with full throttle and full up elevator. I even managed to lodge it some 15 feet up into a tree after becoming disoriented !!! The model was retreived, however, with the help of a long branch laying nearby. Other than a couple of nicks in the prop, it was virtually undamaged. Hah !!! I played with shifting the battery slightly, tried adding a little weight to the tail, changed the rotor angle slightly, but there was no significant improvement. To my delight, the rudder-only steering worked just fine. There was no problem with motor torque causing unwanted reactions.. So I am in need of some advice from an AG3-2-40 flyer. The plan calls for the CG to be located 5 mm in front of the rotor axle. Is this measurement taken at the top of the pylon, or do I draw a line down through the rotor axis to where it intersects the thrust line and measure 5mm forward of that point ?? There is a big difference between the two. I sure would appreciate any help.........Thanks Guys !!! Charlie

Charlie,

My early flights at 5mm in front of the rotor shaft proved to be slightly nose-heavy. I now simply hold the top of the shaft (with the rotor installed), and move the battery until the shaft hangs vertically. The fuselage points down at the same angle as the back-tilt of the shaft. Mine climbs well on 2S with a comparable motor; I can't imagine why yours won't climb.

Hi Gary, Before I flew the model, I held the model by the rotor shaft and gave it some throttle. It easily pointed its nose skyward at partial throttle. The power seems to be there. The model must have been too nose heavy. I've already relocated the battery further aft. This gyro is ready to reach for the sky !!! Thanks for your help, man. Charlie

Hi Gang, I am happy to report the test flight results were much better today. After a bit more juggling of the battery pack at the field, I found a sweet spot and away she climbed. A bit of wind had developed but it seemed to handle it pretty well. I'm a bit rusty and flying out of a small ball park so I was a bit nervous. It has been 5 years since I've flown a gyro, but soon it was fun. I used up a few batteries then came home to more permanently mount the battery. I can attest to this models durability. There have been several minor repairs, but this depron stuff is great to work with. Foam-safe CA and Zip Kicker = I will also say that this baby is a floater !! Power off glide with the 40" rotor is spectacularly slow !!! At @ 8 oz., the loading must be low. All in all, I am happy with this design. Hats off to Gary for designing a real winner !!! I will be back out there tomorrow to get some more stick time. Happy Landings !!! Charlie
