If they aren’t built as strong as they are supposed to be, they’ll fail in flight, hit the prop, and likely cause loss of thrust. So perhaps they aren’t structural, but the strength of the cowls are critical.

Thanks😃. If doesn’t weigh too much it will be pretty good... The more hours per day you build, the less overall hours it takes.

Ok, so if a build time is 3250 hours and you build an hour a day, 300 days a year, then it takes almost 11 yesrs. The point is, for many builders (myself included) its not parts availability or money.... its hours available to build each day.

Good question, and although I don’t know the answer I’ve never seen any airplane parts built out of chopped. The strands in chopped are short and it likely isn’t considered structural (and the cowls are structural).

It takes 4000 hours to build a Cozy... so if you build an hour a day and work on it 300 days per year then you have a 13 year build. Thats what takes time... how many hours per day can you work on it?

Ebay... bench cushion

Still on!

Yeah I suppose you should when someone says you’re a big mouth with clean hands.

Well... you can't patent a method to make homebuilt airplanes because people can do what they want. Your idea can work, but it does seem to require molds, which is extra work. Plans: Cut foam, cover with glass (then filling and sanding) Your Method: Make a mold, cover with glass, fill with foam (no filling and sanding... use gelcoat like a fiberglass boat) Molds are much better for mass production.... but moldless is less work at home for single airplane construction. Big Mouths... dirty hands? I built this with my dirty hands....

They 2 stroke? Props can only spin at 3000 rpm max..... what is the hp at 2800 to 3000 rpm?

What do you propose to give the skins their shape? The Rutan methods are very easy to build..... the only sanding needed is final contouring before paint (same type work needed when restoring a classic car).

I have seen seals like that on Cozy aircraft and they look pretty good.... but you still need to do most of the work.

I used some spray foam in my gear leg fairings and used pour foam on my strake fairings. The spary foam stayed softer and did not sand as well as the pour foam.

How will your design differ from the Quickie?

Would you allow me to cross post your message to some other online EZ communities? If so, what is your contact info?

No problem... you park EZ’s with the nose on the ground. They are all like that.

His website works... what is this post about?

Congratulations!!! Building an airplane is a long term hobby, so its ok if there are breaks. Glad you’re back at it! Andrew

Can't forget this one! https://www.youtube.com/watch?v=dU-zw5k2I-I

I like to use white vinegar since it works great for cleaning up MGS and West epoxies, and denatured alcohol for EZ-Poxy.

Its high end equipment....

The RV’s go together like a giant Lego kit, and most projects get completed. The Cozy gets crafted, one surface after another... most projects do not get completed. Do you want to build an excellent kit, craft from excellent plans... or perhaps buy a flying RV or Cozy?

Good news that you already have knowledge of fiberglass construction precautions and have systems in place. I agree that you could use this as an opportunity to grow that program. I won't say that you won't be successful... all you need to finish is effort, time, and money. Most fiberglass projects never get finished but obviously many have. The plans that all of us build with are wonderful and allow projects to end up flying. That Eagles Nest program and the RV12 projects have a great chance of completion. If you get started with your new composite kit project, it should be a wonderful platform for reaching your stated teaching goals and possibly completion. Go for it! Learn as you go... it should be awesome and good for you all for providing such unusual opportunities for you students.

Congratulation on your the project! Although the RV series of kitplanes make great school projects, I don't think that composite aircraft make good school projects. There is too much work involved, too much dust, too many fumes. You'll need an HVAC / exhaust system for this shop room that is not connected to the rest of the school. Think "paint shop". If you'd like to teach composite construction (mixing resin, cutting glass, layups) then this is a good canvas for your practice if the logistics of the shop are OK.

Well that is to be expected since the Cozy takes nose ballast when solo.
