    What a nice relaxing video :) Nice to see the adjustments you made to get the launch, transition and flight. It's well filmed too, with the wide and zoomed in views.

    Got 'o mighty Friday, that sure does signal lift! I saw that wiggle on the last flight. Looking for a good razor plane and building one......don't want to sand that much!

    Bruce Kimball is your man for the best razor planes ever. I believe Hope put the details on our website last week. As for signaling lift, it HUNTS lift. Beat 4 former national champions this weekend before I screwed up the DT rigging and lost it. Absolutely unbelievable performance from this bird. It uses a slightly thicker airfoil which makes it float like crazy too.

    Nice flying! Very insructive as to launch and transition. The elliptical shape tip was considered the best for many years, now sweepette or triangular tip is favored. Is there evidence supporting this or is it only fashion?

  • @joshuawfinn

    @joshuawfinn

    2 жыл бұрын

    That's a really good question. From an aerodynamic perspective there's no denying that the Sweepette platform is superior in efficiency. That said, my experience continues to show that the old elliptical shape is far more forgiving on launch and allows confidence to throw at 110% because you know for sure that the plane will make the most of it. We also compared this plane to several others at a contest this weekend and it hunted lift the best of any plane out there and showed a dead air sink rate competitive with the other models.

    Question, you are right handed. So you are going to curve launch it towards left. Why trim the airplane into a right turn instead of a natural left turn?

  • @joshuawfinn

    @joshuawfinn

    This is an interesting question and the best answer is that gliders in general do best gliding in opposite direction to the climb. So for a right handed catapult, you'll climb right and glide left. Indoors is different, at least in low ceiling, where it's much easier to climb and glide the same direction.

    and why arent you ever adding a motor, you know you wouldnt have to chase and pick it up as much, just saying . i dont know why I watch your videos, its mostly listening to you explain what your doing cus its very interesting listening to someone bright as there in there element. but my mind just over focuses on the soar's u demo would scream with an overhead 50mm EDF. a few energy drinks and we might get u motivated lol. one thought i been wanting to comment to you is that you like the elliptical foil and winglets have you ever put the winglets in a swept back fashion, so they start after the point of CG, seems like that might benifit from even less drag

    I do actually have several very fast racers and sailplanes, haven't shown all of them here. Not a big fan of edfs...not exactly efficient so if you wanna go fast, it's back to direct drive with APC or Koch props. As for winglets...a lot of these birds are freeflight so we're balancing both stability and performance. I've found that swept wings in general can have some pretty nasty stall characteristics so they must be approached with particular caution. The forward elliptical sweep of the model in this video was purely for the sake of forgiving launches, but head to head against a swept wing it showed no loss of glide performance.

    ... I've seen a lot of your vids. and realize for me that "real", satisfying outdoor gliding (... here at 14:00Min. ...) is only possible from a wingspan up of approx. 80 cm ... It appears that the weight of the material and the outdoor conditions limits the smaller spans in terms of gliding. Ich habe viele deiner Vids. gesehen und für mich erkannt, dass "echter", befriedigender Outdoor-Segelflug (... hier bei etwa 14:00 Min. ...) erst ab einer Spannweite von ca. 80 cm möglich ist ... Es scheint, dass das Gewicht des Materials und die Außenbedingungen die kleineren Spannweiten in Bezug auf das Gleiten einschränken.

    You can get very good flights from sub-80 cm planes but I find bigger ones much easier to launch and much less sensitive to minor imperfections.
