Posts made past 02:30PM 12/30/24 won't be on the new site!

Well, things are going to happen in rapid succession now... I'm going to do a final database backup at 2:30PM CST today. After the vBulletin team gets it - the new site should be operational "with all posts" soon thereafter. Then following a series of checks, and if all goes well, I'll post a link to the new forums here soon.

Thanks for your patience,

    I'd be scared to drive my "flying car/thingy" on the road. Have you seen how people drive these days? One bad driver is all it takes and now you've lost both your car and your airplane.

      I agree with you that trying to join the morning commute on city roads would be asking for trouble. Ideally you would land vertically at the heliport on top of your workplace. If your craft is not VTOL you would land at the nearest runway and catch a taxi or bus if the journey is more than a couple of miles in an open country area. The flying car is best for the first part of the trip when you drive from your house to the nearest place safe to takeoff.

        I figure the infrastructure would have to allow landing spots on roofs if the "flying VTOL car" becomes mainstay.

          If you wanna go electric you ought to concentrate on this:

          Curtiss JN Jenny - Wikipedia
          https://en.wikipedia.org/wiki/Curtiss_JN-4


          Jenny 2 hr range and 60 mph speed is very doable with electric today.

          Jenny engine weighed 177 kg and produced 90 hp...but weighed ( the whole contraption ) 630 kg.

          You can get 90 hp power outa 15 kg electric engine.

          You only need 40 hp to get two outa ground.

              Electric racing planes do not need to be slow. Over a short race they should be able to be above 400mph and may soon give the unlimiteds a run for the money. Range is obviously the problem at the moment, so after a few laps they will be stuffed.

                That is correct. Peter is flying legally with a Part 103 craft.

                  Wonder what these EDFs could do in a superlight electric Avro Vulcan like homebuilt ?

                          Exactly Bob !

                          Labelling electric flying a political matter is against everything an aviator keeps sacred.

                            Test !

                            Above is a sketch of an aeroplane that produces today 6 x more power from the sun than Solar Challenger in 1981...with identical span and Solar Impulse wing loading.

                              Not all flying wings are safe and stable; https://www.atsb.gov.au/publications...aair198902600/

                              I figure the above displayed plane can cross the Atlantic via Azores to New Foundland from Portugal ( 1500 km and 2800 km legs daytime at very high speed at high ).
