      The first flight on the video was the best I ever got out of it. It has been a consistent flyer, but not usually as well as that! Thanks for looking in. I found your channel very inspiring.

    It's hard not to, but when you have a HLG that flies like this don't become too attached. Better, build another right now. You can launch a HLG much higher by attaching a hook some distance forward of the CG and using 1/4" rubber and fishing line as a high start. If you do this be prepared to part with it. Thanks for the fun!

      @@larzhillbot1443 I use a small hi-start with my KK Dolphin...I might have to try it on a towline/hi start. It's trimmed for catapult now, so I think you might need a little incidence in the wing for a hi-start. Currently set at 0-0.

    I seem to remember a Polaris being by far the most successful glider I ever built. I'm sure I never got impressive flights like this but as a 9/10/11 year old I was more than happy.
    I could never get tissue cover models built without warps and twists, even with my dad's help.
    I even built a second one after I lost the first.
    That was in the late 1960's. I've no idea what happened to it.

      Hello! The original design was for a HLG but I use a catapult with the standard 2- 9" loops of 1/8" rubber. So simple, yet challenging.

  • @downwindchecklist6567
    @downwindchecklist6567 3 года назад

    Impressive. Now I need to build one of those myself. It's great you have such great flying grounds. How do yo do the launch? With a stick and rubber catapult, or by hand?

      Sorry, I've been out of circulation for a few weeks! They are all catapult launch gliders. 2-9" loops of 1/8" rubber on a 6" handle. OK, I "cheat". My handle is more like 9" long. Thanks for watching!

    • @kenkingsflyingmachines2382
      @kenkingsflyingmachines2382  3 года назад +5

      Hi, Paul. I lengthened the tailboom and made the tail feathers about 75% original size. Also I tried to get the wing and stab as close to 0 angular difference (decalage) as I could.

    • @kenkingsflyingmachines2382

      Hello! I am happy to share the design data I recorded. I have the tail moment arm recorded as 9", the stab area is 9.42 square inches. I did some experimenting with smaller tails on longer booms, and I think the tail feathers are now about 2/3 original size. I also did some undocumented playing around with the size of the rudder. I am discovering the relationship between rudder height, dihedral, and tendency to loop on launch. I think I have a reasonable compromise now.
      I am sure you have your own airfoil ideas, but this one has the high-point 33% back from the leading edge. Given the elliptical nature of the wing, that high point makes a straight line from tip to tip. I think the high point should be closer to 25% of the chord, yielding a curved line.
      Good luck and share your results!

      @@larzhillbot1443 I'm using 2-9" loops of 1/8" tan rubber on a sawed off wooden spoon handle with an eye screw in the end. I'm sure it's not contest-legal, but it works well. My different gliders need different angles and tension, etc for successful launching. The Polaris needs what I consider a "big" launch, about 45° up. I don't have video of the transition...( I need to work on that)...it does a dramatic smooth roll at the top if I get it just right.

      Hi, Pualo. It's catapult launched. I use 2-9" loops of 1/8" tan rubber on a cut-off wooden spoon handle.
      The horizontal stab hits my hand a lot on launch and knocks it off, which is a problem.

      Hello Mr. King! Thank you for your answer!
      You see, I was wondering how do you manage to launch that glider so high and It didn't seem it was with an Hi-Start because if it was like that, we probably would notice it on the video. Now, I know!
      More, It has to be a joy to achive that high and then watch the bird coming down gliding that slooooow!
      It is awesome! Mainly because it's a solid balsa plane (I know that in the video, you say 21grs., it's not a stick & tissue craft and the air conditions seem quite nice but, even so!...)!
      In Portugal we have this saying: "The simpler, the better" (I believe you have it, too) and, there you have it!
      Congratulations on a very nice well built plane and top flights!
      Keep them coming, please!
      Cumpliments!
