I know there are electric powered sailplanes but

Isn't a Benson a gyrocopter, not a helicopter? Gyrocopters can't hover, they rely on airspeed to spin the rotor, correct? Scott You are probably quite right. All the Benson's I know of are gyrocopters. My intent was to convey the very light weight design. This was a true helicopter powered by an water cooled outboard engine of some sort. It was about 30 years ago so I don't remember the details. Greg |

How about 100% electric powered ultralights? What problems can anyone forsee to building a 100% electric ultralight aircraft for short & mid-range commuters to get back & forth to work (aside from air traffic issues... it IS a big sky after all)? I understand the average commute is less than 30 miles in land based vehicles which would generally mean less than a 30 minute flight for most people. Of course, ultralights are currently restricted from flying over neighborhoods, so there would have to be some changes in regulations for the average person to take off & land an aircraft from their front drive, but wouldn't it be a reasonable idea? And, by the way... does anyone know of a decent 100% electric ultralight aircraft with plans available for homebuilders? They already exists as prototypes, in both trike and paraglider form. And both are FAR 103 legal ultralights. You can buy the trike today. http://www.electraflyer.com/index.html http://www.electricppg.com/ If you have not played with R/C electrics in the last 3 years, you have no idea how far battery technology has come! /Adam |

Scott:
Yes; gyrocopters need forward airspeed for the rotors to lift. Gyrocopters were/are known as autogryos (for the auto-rotation of a helicopter). The rotors of a gyrocopter are not powered (except some that have a little drive off the engine/propeller to get it turning a few RPM to make a shorter takeoff.

While not quite on the subject, a fellow built a very light (Benson- type) helicopter to commute to a company I use to work for. He landed it on the corporate helipad. By the time people were through beating him on the head for such an act, he finally was allowed to truck it away with an escort. I'm glad he was at ground level or he would have had to dismantle it. Personally I thought it made perfect sense. It was a very well built machine and he was an expert pilot with about an 18 mile commute over a typically jammed freeway. The fire marshals and the insurance companies were the main attackers, not the FAA.
