    Tandem vs side by side marketability?

    Hello Unknown, Thanks for the kind wishes.:) It might take a little bit more than luck to make it happen but sometimes it just happens. For example. If I am first to make it...I will find out how many other parties may be interested and divide the cost of the mold by the number of...

    Tandem vs side by side marketability?

    Hello Grimace, Experiencing some delays and setbacks at the moment due to a heavy business load...but don't worry. The LSA tandem in composite for less than $60K is on the way to fill that little gap for the rest of us.;) Gray

    Hello PT... Excellent work with project and pictures. How does PTU 720 sound for the UL3 = PT, that would be you, U, that would be Ultralight and 720, is the weight.? Just a thought to get you thinking.

    Landing a no-engine Airbus 320

    Hello, Your point is taken sir. VFR does not allow night flight when they are all tucked away for the night waiting...but again...I think we both agree to be grateful it happened during the day and not at night or during a special event and that everyone survived regardless of how it is...

    Landing a no-engine Airbus 320

    Jim, My apologies to you and this forum and all other members offended. You are of course correct. I didn't think I employed political or religious rhetoric, but if it is perceived as such, I will cease and desist. I agree with you wholeheartedly that it is all about opinion and belief and...

    Landing a no-engine Airbus 320

    Hello, No miracle to you. It is a miracle to me for the same reason you define. I can't explain it and even if I could it would not change my mind about it because it is a miracle. Too many times we trust that only a scientific explanation matters but that is a pretty weak argument because...

    Landing a no-engine Airbus 320

    Ahoy there It's called faith. It is something many are and do kill or die for. I'm not sure whom it is that you know that runs around saying everything good is an act of God and everything bad isn't so perhaps you should pose that question to them. Me however, I believe their "faith" is...

    Landing a no-engine Airbus 320

    Hello, It is a miracle that no one was killed. The Hudson was without a doubt the best place he could have chosen...possibly on that day. If you're from around here you know how bad things could have been because of the enormous amount of naval traffic that can usually be found. The ferry...

    Hello Mac, I checked it out. It is very nice indeed. Too bad the bird broke a wing but at least everyone was safe and the problem was found. Hard way to learn the lesson, but she sure does look really nice. I have been recalculating all over again and find that I am very very close to the...

    Hello to all, Mac, thanks for the pics. All spars follow the symmetrical shape of the leading and trailing edge taper. I say symmetrical because the tip is centered. If the trailing or leading edge were perpendicular to the center line, then it would still be a .5 taper but not symmetrical. The...

    Hello Topaz, I agree with everything being said by you and Orion and I thank you for your kind words. I will go back to the book and work it as you have suggested. Jumping around has caused me to go back to several iterations quite a few times like you pointed out. Thanks

    Hello Orion, It is my unqualified opinion that this has been covered. If and when the time comes a second "qualified" opinion is always an option and some of those errors can be mitigated. I consult this forum often and that has been helpful. I never thought of it that way but I would...

    Personal Design

    Hello Topaz... Well, actually this has already been done with the other ring frames beefed up as well because I calculated the components to a factor of 5 instead of 7 and forgot to add them to the drawing. I will need to reposition and recalculate them a bit further, but I'll leave that for...

    Hello to all, Thanks Topaz...I got over it fairly quickly.:) Okay. I completed the general structure arrangement for the V Tail and the fuselage so I am attaching some pictures for perusal. Please feel welcome to point out anything that may appear to be out of the normal. Obviously some...
