Probably comes from 28 years of hang gliding and 20 years of gliding (45 years total). I played around with powered ultralights, but never really wanted one. I have a self launch endorsement in gliders (as well as two turbojet Type Ratings in jet powered two-seat gliders), but I prefer unpowered flight for the challenge, as well as lower complexity and lower insurance costs. Sure, I am forced to depend on tows, but you can pay for a LOT of tows with the differential in the price of a motorglider. As far as propulsion type, I don't particularly care for the limited battery capacity due to poor energy density compared to fuel. And don't kid yourself that batteries are completely safe. Any energy storage system has risks of 'dumping' that energy in an enthusiastic manner. Everybody screeching about getting rid of oil & gas had better do some research on what it takes to produce a wind turbine. (Hint: They don't grow from magic beans.) And you might not have noticed, but there are NO solar-powered solar cell factories. And the Tesla S 100 kWh battery (1,375 lbs.) stores the energy equivalent of 2.1 gallons of AvGas. Perfect solution would be a battery-powered winch. Hook a bunch of batteries up to a motor, hook the motor up to a drum. How hard could that be? No folding props to deal with, no certification, no annual inspections, no insurance, no skilled labor required to run it. Plus you don't have to carry a load of undumpable ballast around with you all the time. http://www.startwinde.de/startseite.html -- -- Martin | martin at Gregorie | gregorie dot org |
