I'm curious about building a Long EZ and was wondering where do I start? It seems like plans are hard to find. Would I purchase foam cores from eureka cnc or try the hotwire method?

I'm curious about building a Long EZ and was wondering where do I start?

I would start by downloading the plans off of the internet and get familiar with the build process.
You could also consider getting the Basic Composites kit from either Aircraft Spruce or Wicks Aircraft

 

It seems like plans are hard to find.

Download them.

You have a long way to go before you need to worry about cores, however when you get to that point I would recommend Eureka cores.
Also, join CSA (www.ez.org) and get a directory of builders/flyers in your area.
I know that there is a Long-EZ in Denison, IA. We have a Berkut and 3 Velocity aircraft in our EAA chapter (Omaha).
I have to believe that there are some in Des Moines.

The EZ plans are on this site. http://www.canardzon...um/394-open-ez/

Long-ez projects come up fairly often on Barnstormers.com.

I was looking at the BOM on the Long EZ plans and I noticed that they ask for 5 pieces of .8" x 24" x48" of PVC r45 foam, Aircraft Spruce or Wicks doesn't stock .8" thick PVC. This foam is used for the fuselage sides. I was wondering what did everyone else used for the fuselage sides? I've been watching a lot of the videos this guy has made 

in the comments he says he used Dyvinicell from aircraftspruce.com.

 

I was wondering if the 3/4" foam would work or what people have done in the past? I went through some of the Canard Pusher newsletters to try to find anything about materials change with regard to the foam for the fuselage, but came up empty.

Without going downstairs to check the plans, I would think .75" foam would work for .8".  The thing to know is that PVC is used because the sides will become part of the fuel tanks so you want a foam which is impervious to fuel.

 

The EZ is old enough now that newer materials are sometimes used.  If you take a look at Cozy builder pages and see what they're using, you can substitute those foams.  They are almost built the same way.

 

BTW, I might suggest you look at the Cozy IV before you commit to the EZ.  The EZ is fun airplane for solo pilots but the Cozy has more utility and your pax will like a Cozy better.   My wife likes flying in the Cozy; not crazy about the back of an EZ.  The effort to build either one is about the same and the Cozy has a better landing gear mount system and engine mounts than the EZ.  A Cozy would cost you maybe $5000-$10000 more to build but they are worth that much more when you sell them.    The downside of the Cozy is that you have to add and subtract ballast with a front-seat pax whereas the EZ doesn't usually require that.

The Long-EZ is still a quite popular design.

I have a Long-EZ project that I have on the back burner until I can get the Velocity I acquired. I figured it would be a great way to get some canard time while I'm building. While a 4 place canard is roomy that extra width comes at the cost of performance.

 

The Long-EZ is easier to build and the back seat is such that you'll never have to be concerned about big shifts in CG when a passenger gets out.

So if you don't need a "Grand-Canard_O-Van" stick to your guns and build the Long-EZ.

 

Another thing to consider is what is typical of your flights. I have rented plenty of 4 place span cans and the vast majority of my flight time is solo and I could count on one hand when I've had more than two on board.

 

Don't get the mini-van if you want a Corvette.

I find others generally enjoy flying in the Cozy vs. EZ for the following reasons:

- the pax/copilot can see more

- the pax/copilot can follow the nav and see all the engine instruments

- the pax/copilot has access to all the controls.  Other pilots like that.

- if you are checking someone out, it's easier for them to land and for you to instruct

- apprehensive fliers are reassured by sitting in the front seat

 

Cozys and EZs have similar speeds, roll-rates, takeoff and landing speeds.  I own both at the moment; enjoy both of them.  The main difference for me is the ballasting.  I will probably sell the EZ when the medical rules get settled and keep the Cozy.

I'll probably sell the Velocity once my Long-EZ gets an AW cert.

 

....... but you can wait a few months and buy Kent's EZ and save a lot of build time.

 

I would suggest too that you keep your ears/eyes open. I know of three planned canard fast-build solutions in the works.

 

  • A single place canard.(six week estimated build time.)
  • A two place side-by-side canard (similar to an e-Racer)
  • A two place tandem seat canard (Berkut style called the Mako)

 

There are changes on the horizon.

Mark,

Im Des Moines and have been doing a lot of home work on building the Long Ez, I think we should talk and bounce some ideas around. I do know of a couple projects but I'm really not sold on someone else work if Im going to be flying the plane around, my email is tkielty73@yahoo.com send me your contact info 

 

Thanks

Tom

Yes, definitely join the CSA. However, while www.ez.org is also a worthy site it is not as you imply (the CSA itself).  There are several west coast canardians affiliated with that site.

 

The Canard Zone has a page for CSA information here (as well as in the menu above, labeled CSA) where you can find the email address for the CSA's editor, Terry Schubert.

Looking through the BOM on Chapter 2 for the fuselage sides in Ch5 it calls for A6-80A bolts. I found a supplier that has A6-80 bolts. the only difference is that the 80 has a hole drilled into the threads for a cotter pin and the 80A doesn't. Has anyone used these bolts before and are they safe to use?

Yes, the -80 is safe to use.
