  • Hi, I edited my statement but wanted to ask you if my thinking is correct here:

    ... it seems a significant benefit that the motor has peak torque at zero rpm and reaches peak power (still at peak torque) at 3600 rpm and maintains peak power throughout rpm increase. So, if we sized a prop for 4000 rpm with enough blade angle that we use max torque spinning at 3600 at standstill, and as forward motion eases the torque load on the prop and increasing rpm, we still are at max power, and maintain max power throughout takeoff just as if we had a constant speed prop. Am I talking out my trailing edge again or does this make sense?

    Thanks

    How is your project coming along? I enjoy reading your posts.

    Question: StarJar has an airplane top view called a starjar avitar at his logo on Homebuiltaircraft. View Profile: StarJar - HomeBuiltAirplanes.com

    It would appear that it might accomplish the same function as your 3d wintip/elevator design. I watched all the Ytube videos with you at Oshkosh and I think I understand what you are doing, and agree, btw. If you look at it, the leading edge would have a vortex that would swirl over and impact the surface at the wing tip trailing edge. I presume the flaps that hang behind the wing tip on the avitar would act to control pitch. Notice a hing point.

    What is the difference between your approach and the avitor wing tip approach? Would they both not give down force at the wing tip and counter -cm of the wing just like the Synergy 3d design would?

    Hi, I've been following your work on the Synergy Aircraft and can't believe I missed the post looking for SolidWorks users. My name is Dave Goolsby, I am a one man show at Soliex, Inc.. My main business is tool design for machine shop manufacturers in the aerospace industry. I also create shop drawings, assembly drawings...etc. I have several personal projects going such as some minor modifications to my Sonex kit and I'm designing a simple robust wind generator for home or small farm use. I have SW 2011 Premium SP1 that I use for all design and drawing work. I started a website back in July but haven't done anything with it since, it is <a href="http://www.soliexinc.com/">www.soliexinc.com</a>. I would be interested in looking at any work you need done and look forward to hearing from you.<br><br>Dave Goolsby

    Hello.
    its just to ask you a little question. did you prefer an easy to built airfoil by ex. Clark Y (almost 94% flat) or a high performance difficult to build airfoils says: Wortmann FX 61-126 ?
    thanks in advance.
    Alfredo.
