    Using Bondo as a filler

    Recently I've been using the 635 Thin Epoxy Resin System from uscomposites.com.

    I assume you're using this for fill only? Just so others reading this are aware, there are only a few epoxy systems suitable for structural usage. This 635 system is UScomposites.com's own, and there's no information available regarding its mechanicals to compare against the other epoxy systems that are used, and it's an unproven system in terms. @slk23 you may be the first.

    All I could find on it is that UScomposites.com does say that it's for structural use (boats, kayaks?) and this MSDS sheet.

    Jon Matcho's Progress

    An obstacle in my progress on my Quickie and Cozy has been building two Glasair doors for someone else. I'm sure it could have gone more quickly, but I took the long way to learn how to do it. Glasair uses premolded door shells as part of their kit, and the process for fitting the canopy, locking it in, and then sanding and filling taught me a bunch of new tricks on this 2nd door. The picture below makes it look easy. I suppose it would be if I had to do it yet again, but the hangar being ~30+ minutes away doesn't help either.

    I'm nearly done, just needing some metal work and a few trips to the hangar. I am looking forward to getting this project out of my shop and promising myself I will not take on any more projects until I get one of my own done!

    Can anyone tell me how to make the attached photos display inline?

    See   https://fileinfo.com/extension/heic    Change your phone settings to save them as JPEGs.  I can open your .HEIC pics on my Mac. 

    The HEIC file format is relatively new and is catching on, but not fast enough for the forum hosting service to keep up with it. It will happen eventually, but until then JPEGs work. 🙂

    For those who may be intressted, I have a the moulds, the plug and 3 completed glassfibre fuselages, the completed wing spars with installed metall fittings and all the metal parts for one Solitaire.

    The parts are [located] in The Netherlands and are available for free to an interested builder. Please contact me for pictures and more info. The Solitaire parts need to be collected by the interested builder. I will do no shipping or transportation and need to be collected before the end of September 2021.

    That would be an adventure getting those to the U.S.

    Here someone would take you up on your generous offer in a heartbeat.

    Translating AN, MS, and NAS hardware specs?

    I was trying to use ACS' online search with mixed results. I found the search and results to be slightly better using www.skybolt.com. I would have purchased from them as a 'thank you', but their minimum quantity is 100 pieces which I didn't need yet. Otherwise prices seemed on par with ACS'.

    Here's their catalog page with search: AN-MS-NAS Hardware Catalog - Skybolt Manufactures Camloc, Dzus and Airloc Compatible Fasteners

    Thanks. I have what I need now.

    Pre-Build questions from a new (soon to be) builder

    in General & Prebuild

    Phil, welcome to the forum.

    Here are some additional responses to the numbered items in your mega-question 🙂:

    1) Foam. The plans specify the foam to use.

    2) Alternates to foams. Not worth the consideration in my opinion. I wouldn't even consider changing the foam material as the cost/effort-benefit would not be worth it.

    3) MTOW vs Max Ramp Weight (and Max Taxi Weight). I just learned something trying to figure out what these two new MRW and MTW terms were. Most (all?) small airplanes only care about MTOW as the maximum weight the aircraft can be, whether in the hangar, or about to take off. I have never seen someone thinking about subtracting the 1 pound of fuel they might have burned from the hangar to the runway. 

    4) Round the World. Nobody is going to give you meaningful and specific advice on how to plan a round-the-world trip in a public forum, so expect that. Be prepared to deploy all your cash reserves here. Get in touch with Damon Meyer who was planning to do the same in his flying Cozy III, which he had fitted with a huge fuel tank occupying his entire back seat. After years of planning, campaigning, and real work, he has not been able to get off the ground though. It's a massive undertaking.

    5) The Cozy plans include the Roncz canard plans (modified for the Cozy).

    6) Engines... round-the-world... diesels... turbines... oh my. Build a Cozy IV with a Lycoming 360-type, take yourself to some places, and then your family when you trust everything. It's massive accomplishment considering the success rate of those intending to build and fly vs. those that actually do it. Once you've built and flown in standard configuration, look at your plane and revisit whether it's the one to fly around the world. At that point you will know enough to answer your own questions here.

    Your first step is to buy the plans.

    It's safe to assume that you'll be quite free to do anything you like with the VariEze and/or Long-EZ (or other) silhouettes. 

    For the COBA logo (formerly CSA logo) you should get permission from www.canardowners.com. Personally, I do not see how the COBA logo would be worthy of a jewelry design anyway (the logo is a bit too busy in my opinion, showing a VariEze on top of a runway in the shape of a red 'A', with words, etc.). 

    If you showed up to Rough River with simple Long-EZ, VariEze, and Cozy earrings I think there'd be a fair amount of interest.

    Ben, the best thing you can do to create an aircraft is to get hangar space at the last possible time you can. In other words, building in your basement or any other room, even outside with a temporary canvas shelter, is far better than needing to drive to where your tools and such are.

    As Kent points out, some airports are difficult/unfriendly to homebuilders. You could keep on the waiting list, and just keep putting yourself at the bottom every time your name comes up.
