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.


This is the Roswell Flyer or HMX-4 flyer.
The old manufacturer of the Roswell Flyer
( disapear, but you can still
aquire the HMX-4 at
Model is discontinued and can not be bought.
This is the Draganflyer, can be bought
at It has a much
better frame in carbon.
This is the Draganflyer XP, the big brother of the
Roswell Flyer. Draganfly corp (
sell them.
Glow version, build by a Swiss guy. A pics of this device
flying was published in RCM magazine.
No other info avalaible.
Contact me HERE if you have informations.

Daniel Prelinger version

With no CPU at all only mixing devices and 3 gyro
Page is HERE
His plan is here (not tested and author do not respond) Richards 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
loose direct view on ship (infrared beam which act as a fixed
reference for the control)

Does the Roswell Flyer use stepper motors are simple DC motors ? No it uses cheap mabuchi motor, but each of them is "drinking" 2-3A, multiply by 4 and you understand that with 900mAh, you can only fly 4 min... Do the electronics contain a gyroscope to calculate level flight ? not only one but in fact 3! Does it contain a CPU and software to calculate motor speeds ? it contains a micro controller with no reference and a …
