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

July 5 Tail Construction Progress and Documentation Slide Show

July 5, 2009 Tail Construction.ppt



Progress continues on the tail kit over the long July 4th weekend, during which I've got lots of time to work on it.



I'm using digital photos fed into powerpoint to document, and I've attached the slide show for today's work. The large file size is a result of the many photos that are included.



I started today by laying out the… 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

Canopy propping strut for 601 forward tilt canopy

There has been some discussion of devices to prop open the forward tilting canopy among the group lately so I decided to describe the one I made.





It is a strip of 6061-T6 aluminum 1/8" thick, one inch wide and about 15 inches long. It has been lightened and the last lightening hole is made a little larger than the rest. That one can slip over the canopy latch striker.





At the… Continue

Another 13.8 Hours And 1,254 Miles For The Log Book

Last Saturday morning about 11am my trusty Zodiac XL carried me away from my home base at Santa Rosa California (STS) looking for adventure. After stopping in Cloverdale (O60) for a load for fuel it took me out to the coast hoping for cooler air. She headed north along the Pacific Ocean past Shelter… Continue

Testing larger "bushwheel" tires on the STOL CH 750

Those of you who have visited the Zenith factory lately have noticed the larger bald tires on our STOL CH 750 demonstrator. We've been testing these "off airport" tires this past month and are quite pleased with the results.



These affordable (non aviation) ATV tires are smooth and treadless (21x12-8) measuring about 21-inches tall. Mounted on an 8-inch Matco wheel, these larger tires raise the height… Continue

Fall River Mills Flyin

Qsp attended a flyin at Fall River Mills last sunday a pancake feed and did they feed us. Eggs cooked to order extra large ham slice great pancakes and a host of freindly flyers. We had two xl's there and our demo 701 stol. Brad Demeo and Steve Smith were the xl owners. The show was over at 2: oclock after departing Steve left to go find more airports that he has not landed at. This appears to be getting harder in CA for him Steve has been to almost all small strips in the state. Brad and I… Continue

CH601HD Bungee & Gear Leg Replacement

Well... Yesterday I started into job on the CH601HD that is very much like force feeding a Porcupine to a Grizzly Bear ! I used an ATV jack to lift The Zen, there is no weight the wings... its a "Plan B" thing. Grantley Este & Bob "Mr. GoodWrench" Braden pitched in to get me started on the job I have been putting off for a year now. Changing the out of date main gear bungee (5 yr replacement cycle), so far it has taken 3 guys the better part of a day to jack up the aircraft and get the gear… Continue
