I had the opportunity to build a Quickie many years back in a project
schoolflight class with a bunch of high school kids. Many years after
touring the school, I could still smell that RAF epoxy in the room, even
after the school tried to cover it up with paint! I can remember the kids
all wearing rubber gloves and smearing hand cream on to keep the epoxy off
their skin. I can remember the kids "itching" to get home after a night of
sanding parts. I still don't know what long term effect it had on my health.
With my Zenith 601 XL, the only clean up is my shop vac picking up the rivet
stams off the floor! the 601 is a joy to build, faster to build, cleaner to
build, more satisfying feeling of accomplishment after the parts are made,
and I feel it's about the safest homebuilt plane on the market along with
other aluminum planes like the Sonex. Living in Oshkosh and working for news
radio on the convention site, I see the planes that have accidents during
the convention. When I arrived on the crash site of an EZY, I couldn't find
the plane, just very small chunks of foam and glass that could fit in the
palm of your hand. I also remember seeing a crew picking up the remains of a
Glassair with a shovel.
You can't beat the value of a 601 (any style). Even if you decide to abandon
the project in the future, there is a big market for the parts you made.
It's safe and economical, you can land it on a dirt runway, it fits a big
guy, engine out landings are safe and survivable, visibility is excellent,
and there is a huge support group. That's what sold me.

Very well said, Joe. You'd be a good used car salesman.

I think we've found a spokesman!

I guess it all depends for what you are looking... If it's speed and slippy
there is no doubt the glass will win out. If it's durability I don't think
you can beat the aluminium.
When I did composites in trade school we had to wear full one piece body
suits... A fresh one every day, two if we took off the suit for dinner (a
must). The suits and the positive ventilation of the composites room kept
scratching to somewhere around nil.
Aluminium can also bring you into contact with some nasty chemicals like
Alumiprep and Alodyne. The nice thing about aluminium is it is totally
inert to UV radiation. You can also come across a few things like
dissimilar metal corrosion but by and large unless you want to build a race
plane or be the fastest kid on the block I think aluminium is the better
choice. There is still plenty of composite you can add to an aluminium
structure if you want...e.g. wing tips, fairings, cowls, instrument panels
etc.

Actually it would make a wonderful article for www.ch601.org Can
someone write up a good article over the pro's and cons and send it to
me for posting.
