just an idea, but on your wing design I think I see an area where you can increase strength. When you cut the spacers that stack inside the wing cut them narrower by the width of the foam board. Then cut a third piece. The size of this piece will be determined by how many spacers your using on top of each other. if your using 2 strips make the thrid piece as wide as the two strips are when stacked on top of each other. So, when you glue your two strips in just like in your video you then take that third piece and glue it in vertically butted up next to the two strips. When you fold your wing over you will now effectively have a foam "I" beam that in theory will add more rigidity to the wing. There shouldnt be any extra weight because your using the same amount of foam, your just placing it differently. Its an extra step that may or may not be needed but it seems like it would allow more wing loading or at least offer more insurance against a folded wing mid flight.

I've stressed a 30" section to 8lbs before it wrinkled. I might now try a test with the I-beam for comparison. I usually throw a carbon arrow in there if it needs to be really sturdy. |

ExAir,
try getting a hold of Vic "AceMigKiller" (e-zone name) for your video work. He is quite good. Vic lives in the Phoenix area and is most active in EDF |

Ed,
You are a true and genuine hobbyist !! I feel like I have a new lease on this hobby after viewing your videos!! I was wondering if you will be doing any step by step builds in the near future of any aircraft?? I'm partial to doing a foamboard clone of a Twinstar II... I'm sick & tired of trying to find a Twinstar II when I need one.. They are out of stock everywhere I look... Scratch building is the only way to go... Michael |

Hey Ed! Thanks for the videos! You already saw my Peace Drone built following your ideas and methods, I just placed an order tonight for some more hardware to get started on another plane or two in the near future! I know Pat's working on a cargo plane right now, I'll probably follow suit and build one too. Dumping things out the back looks like too much fun to pass up...

Thanks Ed for the foam lessons ,i have built with balsa all my life and now have decided to try some dollar tree foam .I dont like flat wings so when i caught your wing build it is going to help me alot. Thanks again Ed for the hard work and videos to help us with foam.

Here's the newest aircraft I've built using the described techniques. A semi-scale SC.7 Skyvan for cargo dropping.

Very NICE Ed!
Here's my WACO UPF-7 biplane with a 48" span using your wing design. Build thread here [IMG]

Hoppy, that is an AMAZING looking plane! Hard to imagine foamboard coming out so nicely. Great work.
