West sands much more easily and is generally used for finishing. However, that does not mean it cannot be used for structural parts. Personally I would not, as the amount of money you would save is not worth the peace of mind. Epoxy costs will be a minor fraction of the total costs for the plane.

Here's a worthwhile discussion on West 105 and choosing an epoxy system in general. 

I recall MGS (or was it ProSet) was not an approved epoxy when it was clearly capable. At the end of Nat's personal involvement with supporting Cozy builders, Nat was just keeping up with the basics. Since Aircraft Spruce purchased the plans we still don't have an "approved" list of epoxy systems that is actively maintained.

@Marc Zeitlin's presentation and walk-through was impressive. He qualified what we were about to see as "entirely overkill" for daytime VFR, which I understood as he got into things.

I did make a few notes:

1. Marc's panel was done using frontpanelexpress.com. They provide a tool that allows you to design your panel for them to cut out of aluminum.
2. Marc used B&C for many electric components, such as switches. 
3. Marc is a fan of Bob Nuckolls approach to aircraft wiring.

Thanks for the tour Marc.

Phillip built a modified Cozy IV that can't quite be called a Cozy anymore, thus the "Kinda Kozy" moniker. 

The plane has retractable gear and a Subaru auto engine conversion.

The event will be by online Zoom meeting on Friday 7/24 at 8:00 PM Eastern Time (4:00 PM UTC).

I always say that there's nothing wrong with replying to a post from the distant past, so here we go.

I think the Rotax 912 and 914 engines would work well in a Q2 airframe. I was considering converting my Tri-Q200 project to a Rotax, but these engines are not cheap. 

Since 2008 Rotax has established itself in the LSA market, and I noticed that most of the CS prop manufacturers favor Rotax at the 100 HP range over direct-drive Continental or Lycoming engines.

Did MT/a repair shop quote you $8000 to fix the prop? The first question is if your engine has provisions for a hydro-mechanical CS prop.

I just checked: The quote was from MT USA and was for $6,150 with the 2 prop blades accounting for $4,300 of it. I figured I could buy 2 excellent fixed pitch props for that price. The unit was electrical, so "no" on the hydraulic question (the engine is a Continental O-200).

Being a propeller engineer I plan to get a constant speed prop put on the thing, curious if anyone else has a CS prop currently?

Now you got me looking into CS options for my Quickie TriQ-200. It had an MT prop on it. After a nose gear failure splintered the 2 blades, I decided to move to a fixed pitch considering the $8,000 approx. to repair.

Also I happen to be bias due to my employment and will be putting a Hartzell CS prop on it

I don't think Hartzell offers anything in the sub 120 HP range (for my Quickie)?

Welcome Evan!

3) I see lots of talk about nose extensions on the Cozy....Why? 

Whether this is for Long-EZs or Cozys, your question sums it up:  Why?

My take is that longer and pointy noses imply a faster airplane. Aerodynamically there's no advantage here.

Once I finish renovating my house I plan to get myself some plans and start in on it. 

Make sure you include time to renovate your shop/garage/shed/barn/dining room/etc.

I have seen some use MT props, but they're expensive as heck.

I have a buffer with an 8" mud hog wheel on it. Is the blue foam structural as well? I feel like there is lots of threads on the foam as well.

The foam is for maintaining overall structures, just like in that video you recently posted. Its job is to keep the fiberglass in position.

Just got done doing an extended nose using my CNC router to cut all the internal structure using tab and slot construction.

Jason, a picture please please, pretty please. 🙂

A case for balsa... interesting. The only thing not mentioned is that balsa is an organic material which will eventually decay.

2. Don't move house every 12 months, it takes a long time to get the workshop set up and functioning again!

I totally agree! I forgot that my current shop is now my 3rd from when I started (along with my 3rd home). Very disruptive and taxing. Every time you move you have a whole world of more "honey dos" and "must do" before you get to work on your hobbies.

It takes 4000 hours to build a Cozy...

4,000 hours will get you a really good Cozy, which Andrew is building. If you buy all the prefab stuff possible, and build "good enough" you can come in under those hours. Still, that's a reasonable number worth coming to terms with.

The fastest Cozys have been built in ~18 months I recall.

In the final phases of getting an Open EZ build in motion.

I have found that once the build is in motion, the challenge is to keep it in motion. Left unchecked, flat surfaces in a workshop are magnets for non-building stuff.

For Tim and anyone else, do you have any pointers to share about keeping long-term focus? Here's my list:

1. Get in the shop and do something every day, even if only for 15 minutes.
2. To be continued...

Nice... I had the pleasure a couple years back. He's got a nice looking Q2 and I am impressed how well he does with the Revmaster engine.

@Marc Zeitlin will be presenting some of his recent upgrades to his Cozy IV on a Zoom meeting this evening (8:00 PM EDT /  5:00 PM PDT / 12:00 AM UTC).

From what I have been reading and experience in building things [it's] better to improve the process than to change what [it's] made [of]. Keep the foam, fiberglass and all aspects about the plane [the same]. Just make it easier to build. Very little sanding. I believe it can be done.

You understand the key requirement (don't change the design), and we're all ears to how it can be easier to build.

What do you propose to give the skins their shape?

I am wondering the same thing. CNC cutting the foam, even around the fuselage, is the best I come up with.

Hi Tim!

Also, do you still need to by the TURF plans?  

Kent covered your other questions, but yes, presently you need printed plans. TERF offers these, but are not yet available as part of the Open-EZ download.

the plans are copyrighted but Burt has told people he doesn't care, just don't call it a Long-ez because he doesn't want the liability.

This is a key point. Burt has specifically asked for any Long-EZs build outside of RAF support to be NOT registered as a "Long-EZ". We should all respect that and is why new planes should be called something else, such as an Open-EZ, Xerox-EZ, Tim-EZ, etc.

Chaps, I am taking a break from updating this thread.  You are welcome to post any sales you see.  I tried to identify the N-number of any aircraft I saw and post a link to the FAA registry.

It's been fun but as I sit here this morning reading the news and watching the country come apart, it has rather drained my enthusiasm.

Kent, try to think of the Canard Zone as a "sanctuary" from all the noise that's out there.

Enjoy your time off and I look forward to your future posts whenever works out best for you.

Sincerely,

Jon

Is there really anything more on the TERF CD. than already published in Open EZ, and all the CP publications, pertinent to the EZ build?

Yes.  Here's a better break-down:

• Plans
  • You can get a copy of anyone's plans.  RAF used to refer to these as "Xerox EZs".
  • You can acquire the TERF CD.
  • The Open-EZ does not yet include actual plan text.
• Drawings
  • These were originally provided in printed form, to scale, from RAF as part of Long-EZ plans.
  • The Open-EZ drawings are these.
  • The TERF CD does not include scale drawings.
• Canard Pusher Newsletters
  • These contain all the plans changes while RAF was in business.

You need to question how someone else came to the CAD model that was sent to you.  To so so, they'd have to account for all of the above.  For example, the Open-EZ drawings allow you to define the airfoil shape, but do not provide you with information on how many layers of fiberglass are to be used to cover them, and for the winglets, the angles they are to be canted inward.  

I am always concerned about seeing things in 3D CAD where the typical reaction immediately seems to be "oh that's better than anything", but it's just not if the translation from the original source is flawed or in any way.

Make sense?

I think there is a file size limit on uploading images. I tried some just over 3mb and they failed.

Interesting.  I verified the limit per post is set to be 50MB.  Let me know if you have any issues and I'll be happy to review.
