    Ultralight Airplane Workshop on Youtube

    I want to pass along some news pertaining to the mighty slippery UWS-4. Leon has it flying in a simulator. I have enjoyed immensely watching this aircraft being designed. It sure seems very rare these days, where you can watch an aircraft being designed and analyzed. I disregard the mathematics...

    HERO ULTRALIGHT

    philr I like what you are doing. Building the airframe you have drawn in 4130 will be a challenge. Totally doable, but I can assure you, having built a few fuselages, will require hours of tedious fitup of .028., .028 requires a very close fit. Hours of skilled work that most don't have the...

    Ultralight Airplane Workshop on Youtube

    Just wanted to let the interested people know that next week there will be some new videos released. It looks like there some changes coming down the pipe. Flat Wrap sheetmetal construction is a very efficient method to construct an object. Is .016 aluminum sheet too thin to dimple? Would...

    The Ultravair engine is a great choice! Please consider an Aluminum tube and gusset frame. It will be lighter even when adding in gusset weight. Please continue sharing your thoughts

    Possible timeline for the Plans. 9 months to 2 years. This information comes from a private conversation I have had with Bob. I don't believe he would mind me sharing.

    Discusion Thread: Raceair Skylite Build and sub-kit developments

    I have the plans, and am still evaluating what I would like to fly during my golden years. I always "improve" or attempt to existing designs. I have plenty of time while I am working to daydream. The solution is Carbon Fiber. The finish of the widget does not have to be class A. Small scale...

    Bob Barrows and his Electric Ultralight Flying Machine

    I am fortunate to be able to gas weld, well I could a few years back, and will buy the plans as soon as I see them available. Electric or gas makes no difference to me, if its good enough for Bob its good enough for me.

    The moderators are unfair. The reason I will not financially support. I don't want to pay to to have moderators remove my posts because "they" don't like them. This should be a pretty good place to meet and learn, but the regulars on here shut down new ideas. Go on ahead and feel free to remove...

    As a composite designer how do you deal with Matrix Microcracking

    I am coming to the realization that a hole for a fastener (load bearing), in a composite, should be in phenolic.

    Composite Tube Joining

    Let me see if I can be more specific, the fasteners you are developing can be used to join composite tubing for airframe construction? Is this correct?

    Aluminum extrusion spar web.

    VB, it should be with homebuilders. You can order billet in an array of sizes, hog out the scrap with plain router bits. You can rip 7075 1in plate on a table saw.
