    Lazair on Floats with Rotax 185's needs more power, Ideas?

    Trying to find some contact info for Gene Yarbrough. No details on how to reach him or order parts from him anywhere. Anyone know how to reach him?

    Electric Powered - High Performance Design

    Check out this. Not sure if it's a lot of marketing BS or not but it's interesting to see development in motors with enough robustness and redundancy to potentially be certified for passengers. If lots of smaller manufactures like this can share the load of the many (100's of) millions it will...

    And don't forget to include a venting assembly so that each group of cels can vent hot gas and pressure to the outside of the aircraft to avoid a catastrophic explosion or structural damage if the casing inflates due to high internal pressure.

    It's true, Capacitors are not for power storage, they are for cleaning the power up. With electric rotor systems you have a lot of power adjustments and breaking, and the 3 phase power is changing frequency up and down, and this all causes a huge amount of RF noise and interference that mucks up...

    It looks exactly like what a stupid investor with too much money thinks it should look like.

    Electric Powered - High Performance Design

    Also I've been asking around about mixing battery chemistry for increased performance, and so far nobody has any real objection to it. Which I mean that an electric aircraft could have a composite power supply. Starting with Super Caps that are the front line for supply, a few seconds of pep...

    Tony have a look at these motors. They give me the idea that your plane could have 2 pusher nacelles with contra-rotating tri blade props. IMO that would look bad ass. http://freerchobby.cc/e_productshow/?52-Coaxil-Motor-240110160kwTwo-Stator-CWCCW-For-Mega-Drone-52.html

    FPV Freak Buys Lazair for electric conversion.

    These are indeed the most promising I have seen. I have been googling for paramotors and also electric skate wheels which I am after, and never found this company in weeks of searching. So thanks for the link.

    Ok, sure, I'd love to order books, wait weeks, and pour through the books. But I was hoping that somebody could just tell me the formula.

    Those large cavities make me think that what we are looking for in power storage should be very long, mostly air filled, air gap capacitors. So it would feel light as pine wood, but have power storage to weight comparable to gasoline. Some sort of Nano aerogel, graphene supercapacitor.

    Of if you had a few planes, would make sense to get a tesla battery, that buys power sustainably from wind, or low demand time of day etc.. stores it in high capacity, high C cels, that can quickly dump all the DC current direct into the plane that you want. Could get a full charge in about 40 min.

    Tony have a look at this clip. I think it is another great way to show what I think electric is for. Situations where you are looking for extremely low latency reaction time because the maneuvers you are doing require a delicate touch and perfectly even responsive power. IMO Jet turbine is...

    Yes Tony wants zero emissions, but can anyone explain why we don't have gas turbine generating range extenders that could be used to extend the range of an electric aircraft. Has anyone ever tried putting a gas turbine into a brushless motor and see if you can fly a drone on that power?

    I am curious to know if anyone knows the formula for scaling aircraft weight and airspeed. IE if I want to make a scale replica of a full scale aircraft, how do I calculate a scaled down weight and airspeed. Many thanks.

    Seeing a vid like this gives me a bit of confidence in the czech made equipment, and I appreciate the demonstration flight with power readings.

    Electric Powered - High Performance Design

    The issue as I see it is that RN there are no aircraft out there that have been engineered to do this electrically, and to do this kind of flying, you're definately talking about being an Instrument rated pilot in a certified aircraft dealing with ATC. So to push through all those hurdles, to...
