Back DFH Dragonfly 333 / 334
1993

Dragon Fly Model 333

Dragon Fly Srl. was formed by the Angelo and Alfredo Castiglioni brothers at Cucdago in northern Italy to build a small side-by side two-seater which was, initially, designed for their own personal use as an easily transportable machine for use in archaeological exploration. Two prototypes of a single-seat model were built and flown in 1989 as a precursor to the two-seat production model. The Dragon Fly 333 is technically an ultralight, but is built to JAR Part 27 standard and was approved in 1996 under the Italian VLR (Very Light Rotorcraft) standard. Dragon Fly production was set initially at three per month, and the first production machine was delivered in late 1993. Production totalled 51 (up to c/n 51-97) by mid-1997. The all-metal Dragon Fly has an enclosed pod fuselage with fixed skid and a tubular tailboom carrying a T-tail with a two-blade tail rotor. The main two-blade rotor is mounted above and behind the cabin and is driven by a 105hp Dragon Fly/Hirth F30.A2 two-stroke engine. The Dragon Fly can also be delivered as a drone for military use.

Dragon Fly Model 333

Original Dragon Fly company founded in 1993 by twin brothers Angelo and Alfredo Castiglioni specifically to produce the Dragon Fly 333 light helicopter, rights to which were taken over from general engineering company CRAE Elettromeccanica SpA. The company was taken over by German owners in 2001 and moved to a new factory at Ovada. The Dragon Fly 333 is being further developed into the Dragon Fly 334 GP.

Developed and tested by manufacturer to standards approaching FAR Pt 27; initial Italian certification is in ultralight class, but domestic VLR (very light rotorcraft) certification obtained 16 June 1996. Relaunched at Aero '03, Friedrichshafen, April 2003, under new ownership and new designation.

Tony Finn, e-mail, 15.07.2010

I watched this fly when I was on vacation in Italy probably 10-12 years ago and was curious enough to talk to the pilot when he landed in a nearby field. I have my private fixed wing but have always been interested in helicopters. I would like information on the new four stroke design, wondering if it meets us specs. I would also be interested in setting up a dealership in the Chicago area. I believe I would be a top notch salesman. 269-720-1935

Mid 1997, I was fortunate enough to personally view the Dragon Fly 333 in the flesh (one black - one red) imported from NZ for the cattle mustering industry. They were well engineered and easily accessible to work on. However, due to lack of factory support, were shipped back to NZ without lifting off the ground. At the time, the reason from Italy was certification commitments. It's a shame not to have seen these great machine flying. It certainly would have given Frank Robinson and his R22 some competition.
