Another 601XL takes to the air!

I finally did it!



I flew N990MK maidens flight yesterday and everything went well!



No, the wings did not fall off!



All the bantering back and forth about the safety of the 601s had me quite concerned, so much so that my airplane, signed off by a DAR 19 months ago, had to be annual-ed before its first flight.



The most recent letter from the FAA put my mind at ease.



A few minor adjustments and its back off into the wild blue yonder.…

Wing spar webs

Got brave today and cut the wing spar webs. After I come up with some kind of Rube Goldburg contraption to hold everything flat and secure, I'll use the fly cutter to cut the .95 mm holes. Debating on how to do the spar rivets, buy a rivet squeezer or build the rivet setter. Any suggestions?

Flying report

My first flight was on July 5, 2009 around 11:00 AM on a cloudly day with a few drops of rain. After one more runway "hop" I decided it was now or never and kept the throttle full on till lift off.



Performance was not what I expected and it climbed very slow and as soon as I was out of ground effect I had a very heavy left wing. The climb was some where around 80 KIAS and was very slow. After a few circles over the airport and two attempts I landed unevently with a slight bounce.… Continue

New Cowling

The cowling mold has been lengthened and the new cowling's do not have a meal strip. I have deeded to change the cowling to the new one instead of trying to repair the version with metal strip embedded in the fiberglass. I will not be able to get this done before Oshkosh but it will be the the first job upon my return.…

nonstop JAX to PIT

I just wanted to give an update on my corvair powered 601xl. I now have 54 hrs on my airplane. We haven't turned a wrench on the engine except for oil changes since the first flight. Totally smooth and hasn't skipped a single beat.



I flew from south of Jacksonville, FL to Finleyville, PA (approx 20 nm SE of Pittsburgh, PA) nonstop today. Flight time was 5:58. Distance is 626 NM. Nice long flight.



Now I am getting ready to fly to oshkosh this weekend...see you there in the… Continue

How does flying open without doors effect cruising speed and fuel consumption?

Cowling Final fit

I received the cowing from the paint shop and fitted it to the fuselage in order to be able to arrange the fitting of The airbrush work to be done on the cowling. With the cowing in place the fiberglass work over the added metal strips has pulled away and needs to be attended to before I can finish the paint job. This is the bust for being able to have the plane at Oshkosh.…

July 8 Progress Made on Tail Kit

A little more progress made today; check back shortly for slides.



The first operation I did today was to make sure that the tips of the horizontal stab's full ribs, which eminate from the rear spar and flush up against the forward spar at its ends, and the small nose rib were coplanar. The instructions have us do this by placing the assembly leading-edge down and check the three points against the flat surface of the table; I did this, and all three ribs seemed to meet the table just… Continue

Plans builders,I need some advice

Hi everyone,I'm plans building a 750 and at the point of making flaperon spars.I built a 9 foot brake out of solid birch and piano hinge.The brake is very strong and dead straight.I clamped in the blank and bent the flanges as per plans,the only problem is when I removed the part it looked like a banana!All I did to fix it was put some small crimps in the flange but I don't feel comfortable doing this.I then tried again but this time I made a form block the correct size and formed using a… Continue

Tail Construction Continues

Today I made more progress on the tail.



First, I placed the upper doubler onto the horizontal stab forward spar and confirmed that the centerline mark on the doubler coincided with the centerline mark on the spar.



Then I clamped the doubler to the spar in four places, and drilled and clecoed the centerline hole.



Then I drilled the holes a good deal to each side of the doubler and clecoed those.



Then I drilled out the remaining holes through the… Continue

July flight over the Cascades

Yesterday was a holiday for me, so I decided to take a quick loop to the north east of my home airport, Sanderson Field in Shelton WA. I topped off the tanks in my Zodiac 601 XL and warmed up my Jabiru 3300 as I taxied over to runway 23, two mouse clicks sent an email to family and friends telling them that I was taking, and letting them know that they could track my flight with a web based map. Knowing that some of them would follow my flight made it feel as though I was sharing this little… Continue

Tail Construction Started Today

I started the tail kit today, having picked it up at the factory when I went to do the rudder workshop this past weekend.



First, pieces were inventoried: everything is present in stated quantities.



I started by labeling the horizontal stab front spar with "top" and "fwd/aft," and then placed it on wood strips with the aft side up (this puts the lightening hole flange down).



Next, I found the centerline of the spar and marked it with a vertical line on the aft… Continue

Every time a bell rings......

a zenith gets its wings.

Well, not really. Jon Croke and I spent the last few days finishing up the Assembly and rigging for the CH750 DVD series. Now I have to get the engine and panel ready to fly. We will be changing over to the UL260i shortly and are verifying our engine mount data based on weighing it with the Corvair. More updates… Continue
