Bagging wings - A resource thread
I am not a builder but I have a lot of respect for those who like to build.
I have been preparing a section of my weekly newsletter on Bagging Wings. There will be a presentation at our club on the topic at the next meeting. I think I pulled together some good resources so I am going to post them here for those who might be interested. And I encourage anyone who knows hot to bag wings or who has question about bagging wings to post in this thread. Maybe we can get a good exchange going. If my club is interested we might start a "one design" group build around a bagged wing project. If it happens I will let you know and share a link to the discussion. RESOURCES BAGGED WING GLIDERS – THE LOW COST WAY TO BUILD COMPETITIVE TD, ALES and HAND LAUNCHED GLIDERS Many of the gliders flown at the ESL contests at our field are bagged wing designs. Learning about bagging wings will open up a whole new world of options for you. You can make DLGs, larger models, winched gliders and electric gliders that look and fly very much like the high end molded wing gliders.

WOW! Thank you for putting all these resources in one spot. I am thinking about getting started building my own and I bet you've just saved me about a month of research!

So, all you wing baggers! Let's get some input, some photos, some tips and tricks.
Feel free to add your wisdom, your build thread links, your how to tips. |
Anyone in PA, NJ or NY who can do a wing vacuum bagging for me?
I just do not have a space for that and need to find someone in a area who has a setup to do it. I googled a lot - did not find anybody. I have a foam wing cutout with core. I will prep the wing for bagging and either come-up or mail it to you. I live in Poconos, PA, Stroudsburg area. Would appreciate any help or point to the right direction. Cheers, Mark |
