Roswell Flyer, HMX-4, Draganflyer

The Roswell Flyer or Draganflyer or HMX-4 flyer were designed by Mike Dammar at (a very cool man) They all shared a same design, just strong enough to fly indoor. It is the greatest machine i’ve ever flown, and all friends or people in the street agreed. The price is very high (as expensive as a picollo) but the price range is the same with all rc helicopter : all price can be easily divided by 2! I regret that only a few people can buy this wonderful machine but if you can afford one, do not hesitate : buy one, it is very stable in the air (3 gyro) but still required some helicopter knowledge.

His plan is here (not tested and author do not respond) Friedrich had a lot of knowledge using
the basic stamp, great chance of success.
Project Stopped. based on a linux system and pc104 card
(expensive setup). Do not know if it fly. This project is trying to
build a remote flying plattform and therefore use expensive
devices to achieve their target.
Vectron blackhawk, thethered version not so interesting except
it’s low price. ($90) Movered it’s principle do not allow the TX to
