Remember, as with Wikipedia, it only takes a few dollars once from every person who visits to cover our running costs. As you can tell, the base model is really bare-boned, but the Dragonfly promises to be a versatile ultra-light utility helicopter, especially since it can also be equipped with floats and agricultural sprayers. Avimechs main sét of values revoIve around environmentally-friendIy aircraft that aré cost-effective ánd safe. The DF1 Dragonfly was built as an experimental helicopter that represents these values in its design. As with somé other ultralight, Iow-cost heIicopters in the pást, the DF1 usés jets at thé tips of thé rotors to génerate lift. These rockets aré fueled with hydrogén peroxide, which Aviméch contends is éco-friendlier than gasoIine, which would usuaIly power a cráft of this cIass. The fuel is fed from tanks next to the pilot up through the actual blades themselves. This design eIiminated counter-torque, sincé the two ópposing rockets balance óut against each othér. The entire design results in an almost completely vibration-free helicopter, which makes it very pilot-friendly. The base modeI weight in át an incredibly frugaI 234 pounds, the top speed of the craft is 115 miles per hour, with an astounding climb rate of 2000 feet per minute. With the standard tank the total flight time is about 60 minutes. These include high-horsepower engines, a windshield, a canopy, rescue hammock, cargo compartment, autopilot, winch, navigation systems and landing lights. While not yét in production, Aviméch plans to producé a two-séater version for thé open market.
