Big Micro Gyro Trike Version

Notes: I finished my trike BigMicrogyro tonight, here it is ready to go at 56 grams, slightly heavier than the others, due to the extra wheel I guess. I have run it up on the carpet and it steers fine, even though the nosewheel is fixed.

MacGyro

Specs: Rotor: 355 x 90 mm, 13.6g AUW
Material Required: MacDonalds breakfast plates,Parkzone Cessna brick,motor/gearbox, Citabria prop
Downloads available:
Notes: The MacGyro is completely made from MacDonalds breakfast plates, fuse and rotor using UHU glue. It uses the stock Parkzone Cessna brick and motor/gearbox with the Citabria prop. Rotor is now 355 x 90 mm and the AUW with standard PZ battery is 13.6 grams. It is my slowest flyer now and I should be able use it outside at least when it's calm because it is not IR.

The 3 dimensional fuses are easy to make as seen in the bottom pic. The only formers are a triangular piece that becomes the windscreen and a rectangular piece that is the top front. Use UHU glue around the edges. A square of foam in the bottom makes the radio mounting plate. I leave the bottom off to access the radio and save a little weight. This method does protect the radio and is adaptable to any size AG.

These are the average spec of my autogyros. Rotor angle is 25 degrees from thrust line. Negative pitch of blade is 5 degrees. Thrust is more than 70% of AUW. Thrust of your motor is enough for flight, I think. Larger rotor angle and blades pitch make autorotation better but make larger drag too. Anyway,try to fly it first.

Notes: My 5 gram outrunner came from China today and so I finished up my profile Pitcairn Cabin big micro autogyro! I made it the same dimensions as Al's big micro and hopefully it will fly half as well as his!

PZ Vapor Gyro

Specs: Rotor: 1 inch x 5 7/8 inch, 2mm depron,20.8g AUW
Material Required: Depron
Downloads available:
Notes: This is a modified PZ Vapor. "Fuselage", rx and pushrods are all stock Vapor parts. The gearbox is a 4:1 from bsdmicrorc.com with a blue SS motor, and the prop is a GWS 5 X 3. Total weight is 20.8 grams with a E-Flite 110 battery and 1.6 grams of clay ballast on the right main gear leg.

The Elf is optional, the clay is necessary....It flys pretty good. A bit nose up but no bobbling as with the early Osamu style gyro. The rotor head is based on Jochen's design for his V-4 and Nanomum. The blades are 2mm depron and are 1" by 5 7/8". Attachment is with the .025 fiberglass sheet and UHU Por...

Pusher Autogyro

Specs: 114g AUW
Material Required: EPP Body
Downloads available:
Notes: Pretty much same spec as previous one(cessna-type) except body was made of EPP. AUW was about 114g(80g body + 34g battery)
Battery 20used 2Cell 20C 500mah instead of 350mah due to CG. This flies much stable and feel like controlling EZ-star.
Field was about 20Mx20M but it was big enough for it.
