Hi Guys,



This week was mostly bicycle work, finishing travel stops and some tow 

bars, but flying would have been seriously compromised by very windy 

days. I ate lunch with the guys at the Hy-Vee and continued to add to 

the instructional and pictures of the recumbent. It’s getting close to 

the end, save the molded fiberglass seat. Friday, Cy called to say a 601 

was being assembled at Moline #1 hangar having been imported from a 

Polish manufacturer, so I drove the Corvette out to see it. It could 

have been called a knock-off of a 601XL but the workmanship and the 

engineering were taken considerably further than one might have 

expected. A Polish mechanic was hanging the dry sump Rotax 912 engine 

when I got there and within an hour, I helped hang the wings on it. A 

nice plane to be sure and it should be for the nearly $100K it cost the 

buyer. Lots of fiberglass fairing work and a nice split-flap design with 

short ailerons at the ends of the wing. A totally IFR instrument panel 

was completely fitted and the mechanical approach for dual sticks was 

done with serious engineering talent using proper soft stops and 

construction that Zenith might well envy. There’s a lot said about good 

engineering and this one was very complete aircraft down to an entire 

structure of bucked rivets. There were diagonal pieces at every frame in 

the fuselage. The heat muff wrapped around the exhaust muffler as a 

separate stainless entity that could only be compromised by CO2 if both 

containers were pierced. The firewall was stainless and the fuel lines 

were also special stainless tube and the battery sat in its own nicely 

made stainless box. Nose steering was differential braking, which I 

would not care for, but the two-piece spring steel tapered main landing 

gear were very small and nicely integrated into the bottom side of the 

center spar structure. Even a tow bar was latched in the rear baggage 

compartment and there was a tailskid for the possibility of contact. The 

canopy acrylic was quite different by its slightly pail pink UV 

protective color, and though it still tilts forward, there was a sliding 

air door on each side of the canopy for flying or taxiing. The 

overhanging edges of the instrument panel took ducted air pressure to 4 

small adjustable air vents for good circulation in an otherwise 

hot-bubble environment. The upholstery was nice, but the steep angled 

side padding and narrow center panels suggested that people with wide 

bottoms would never become really comfortable where it counts.



It’s going to be a nice plane, but I don’t think it will really ever be 

called a 601, though the initial similarity was remarkable. Perhaps it 

was the fire engine red and white paint job. I can't wait to see it fly.

Stay safe,,,,,,,,

Hi David,

The aircraft had the name AERO Sp and it was serial number 25 of this run.

It had been flight tested and issued Airworthiness Certificate in 

Poland. The wings still

had the letters issued for European registration painted on the bottom. 

Then it was taken

apart and crated to Moline, IL for reassembly. It might take a while to 

get data specific on

this plane, but I'm sure it's out there. I'll try to build a temp page 

for pictures taken on my site.

Might be a couple of days.

I googled Aero in Poland and came up with their site: 

http://www.at-3.com/en/company



Larry, not sure if this is the plane you saw but the pic on their home page has a 601XL looking aircraft. Talk about a quick build kit .. look how they pack it into that container.

Dave,

The aircraft is the AT-3 and it's exceedingly well done.  There were 

several things on it that one tends to learn from 

and look back saying I could have solved it this way too.  The wood in 

the crating I saw was clear, straight grained and

no knots to 18 feet and I would have liked to have taken it home.

Interesting...



I wonder how many outfits in Poland are building 601's.
