Testing Phase 1

After 205 inches of snow this winter, I'm finall able to start knocking off some test time on my 601 XL. I flew the 11th hourof testing this arternoon. What a teriffic airplane ! I'm getting more at ease in it with every flight. The Corvair is running strong, and I'm seeing 1000'+ climb rates with my 190# and full tanks. I initially had to adjust the horiz. stab. angle down 2 deg. I'm still tweaking my cowling a bit to improve cooling at high climb rates. The flaps are a real asset on the XL,… Continue

701 Scratch Builders Compare Ideas

I'm very close to first flight after 5 years of building. I wish Zenith would have had this site up and running 5 years ago. I have learned alot from other builders. But scratch building has its own world so I'm creating this blog for scratch builders (701), such as myself, to have an avenue to share ideas (and frustrations). The feeling of success in your building is well worth the frustrations that are mostly unavoidable. So just share what your going through right now and don't be afraid to… Continue

Back to Wings

Back side of the wing, the rear spar is a two peice affair with a doubler channel, this makes assembly quite simple and fast. Best part is the trailing edge being a bent unit which makes the trailing edge very attractive.

Front skin cleco's right on.

Look close at this picture, the amount of time that will be saved in slat alignment from the… Continue

750 Slats and Flapperons

This pictrue was taken yesterday at 9:26pm and is a great starting point for today.

Here is all the slats and Flapperons, I have made the 701 and 801 slats and I will say that these are by far the easiest to build, no Jigs and they are designed to make assembly simple Hats off to the Boys at Zenith for comming up with this…

601 HDS Move radiator rearward or fit front undercarriage stop?

I am finishing a 601HDS that is fitted with a Subaru ea81 motor. The water cooling radiatior is fitted under the fuselage, close behind the front undercarriage. As there is no stop on the front undercarriage, it is possible for the wheel spat to impact with the underside of the radiator.

What is the best solution to this problem?

I have contemplated fitting a pair of steel cable stops to the front undercarriage to limit their travel and also to relocate the radiator… Continue

Another Fun Factory Workshop

We "graduated" another class of proud new aircraft rudder builders today:

Despite the apparent slowdown in the economy, this group was proof positive that there's still optimism out there and that folks still want to have fun building airplanes. The full workshop (12+ rudder tail assemblies of both STOL and Zodiac designs) included six husband / wife teams, plus four father / son teams, and was a lot of fun (even for the organizers). The… Continue

"Don't Fly Real Fast"

An Australian builder sent the weblink to the following online article published by Recreational Aviation Australia: "Don't Fly Real Fast."

Using plain English and writing about "sport pilot" class airplanes and pilots, the writer explains the perils of overspeeding your light aircraft.

This article is just one in a series of online articles titled "Decreasing… Continue

Good day!

This was one of those days that gives you hope and keeps you coming back. After major trimming on the inboard flaperon it is reinstalled on the pivot pin and is perfect ( no rubbing on the fuselage).and then got the passenger side done followed by top glass, windscreen, both root skins trimmed to the top glass and on, as well as the seats in and riveted....... I felt like the energizer bunny today.... of course I had major help and support from my best friend in the world.... My wife. It makes… Continue

Windows Anyone

The roof is installed, I extended the length over the doors to allow for the water to run off in the wings and not into the cabin.

We have windsheild installation, pretty straight forward, I use the plastic drill bits from Aircraft Spruce.

I have layed on my back on every Zenith model to work behind the panel, the 750 is by far the best and… Continue

Another 1,288 statue miles added to the log book

My mother turned 91 last week which provided the excuse to fly to Southern California and back.

The trip down on 3-7-9 was 444 miles non-stop which I flew in a beeline on auto pilot at 9,500 feet because there was a nice tail wind up there. My average speed was 126 statue miles per hour and the plane got a solid 33 miles per gallon. Try to beat that performance in a car! Flights like this provide lots of looking-out-the-window time and you can literally see half of the state’s width… Continue

Stab Skeleton Rivited

Boy did it feel good to start pulling some rivits. It made me feel like I'm getting somewhere. Now turn the page in the assembly guide and keep going. Yes I print them out. The computer has all the research for my wife's EED dissertation on here, I don't think I can take it to the hanger and live to tell about it.

Motive Power Bolted On.

Today William Wynne brought by our Corvair engine and we had it bolted up in short order. I am calling the Corvair 750 combination a "Savage 750." The Savage has nearly all the necessary components to complete the installation of the engine. Only a few bits differ from the standard 601/650 Zenvair installation. The Weseman 5th bearing doesn't change the location of the prop flange and we are using a cowl… Continue
