    Why would you want an LSA when you could have a perfectly good MotorGlider instead?

    Motorgliders come in various sizes and performance but can (and often do) exceed the useful load, range (legal and physical), cruise speed, altitude limitation of an LSA and do not require a medical. So what obscure worldly reason would cause you to want the excess b.s. of an LSA. Is there a...

    Current cost and future development HP-24 / HP-26 / HP-28 (maybe?)

    I know you are busy, and it is hard to publish a number. But what kind of money and time are we talking, it is just a mystery. Do you have to get accommodations in California for a week or six months or? I am wondering the cost of the HP-26 self launch? How fat can a person be (how much weight...

    How to incorporate a Hydrogen fuel cell into an electric aircraft for Homebuilders?

    It is self evident that a aircraft relying principally upon electric powered motor(s) for sustained flight will benefit from auxiliary power in addition to batteries for flights of significant range. I am posting this thread in hopes of gaining more insight and education regarding how hydrogen...

    Simpler Times and / Briggs and Stratton propellers

    In the 1970's and 1980's when I received the majority of my basic aviation knowledge it was a simpler time. Bernoulli's theorem was not questioned at least not in my world and wings and propellers worked by "suck". Super Cubs like Bic lighters were cheap and expendable IE, a hunter would pay...
