Here's an example of the moisture that comes out of an engine after flying.  My oil temp was the Lycoming-recommended 180°F.   After having had experience with spalled cams and tappets (i.e. rust), I blow it out with an air-mattress pump after landing unless I plan to fly again soon; not sure how much it helps.  I'm sure the moisture, left in the engine, condenses on the parts.  Maybe they are protected by the residual oil film, maybe not, but the film slowly drains off.  If you are using a dehydrator it will help that too, otherwise the desiccant has to extract the moisture, which is also oily and coats the desiccant.

Recently it had been cold here for several days and a warm front blew in.  Everything in the hangar was dripping as moisture in the warm air condensed on the chilled airplane.  Even the fiberglass was dripping.  😞

Ah yes.   Did you know Wilgrove is closing?    Sold for development.  

There are a lot of improvements one can make on an EZ but i don’t know of a comprehensive list.    I guess an O-320 and a longer nose are the main change.   It takes a lot of research to find what has been done before.  Check out the projects for sale in my “sales i’ve seen” thread.    Some good values there.

Hey Kent.  Thanks for the follow-up.  Noticed you are from Concord.  Are you by chance based at Mid-Carolina?  If so, I had a look at your planes a couple of years ago.  Friend of mine (Rick Basco) is based there and flew a Onex that he built.  I built a Sonex and used to fly in and out of there to visit.  I was based at Wilgrove.  Recently moved from Charlotte to Eastern NC, sold the Sonex and now ready to have a "real" homebuilt airplane.  Have the build manual so next step is to get the dwgs printed and get going or maybe find a good project or decent completed EZ.  Thanks again.

This EZ today:  decent price considering it has wings, canard, strakes, cowls and 500 hr. engine.  Ugly nose but that can be fixed pretty fast.  Needs "tip sails"  🙂

I downloaded the Rev 5 drawings about 6 months ago in PDF format and had them printed on a large-format printer at a FedEx store and they were right on.  There was some confusion about the corner marks but it was just a problem with the marks, not the base drawings.  I am sure the Rev 5 drawings are right.  I believe the build manual is still available on Ari Glantz's website.
