Wing skeleton loose fitup

I finished doing a loose fitup check of the main spar, ribs and rear spar. I wanted to convince myself that

everything was going to fit together nicely before I started drilling holes and doing other things that could not be

undone. The ribs were drilled and clecoed to the main spar, but the rear spar was held on with cleco clamps and supported with 80/20 framing. The first pic is a shot of the right wing. The left wing was similarly setup.

To make sure that the…

A NEW, BIGGER STOL CH 801 (re-posted from the CH 801 Forum)

Based on the success of the STOL CH 801-HD as a commercial spray plane (a.k.a. the CH-8000), Zenair has quietly been working on an even larger and more capable STOL aircraft than the currently available HD model. Among other modifications, this new CH 801-EX has 4 feet of…

Rib Stiffeners

I am currently working my way through adding stiffeners to rear ribs 1-4. Below are a few pics of how I am doing this.

I made a gage strip for laying out the end locations of the stiffeners. That is seen clamped to the edge in the first pic. Small 90 degree vee blocks are handy for transferring lines around edges. Another handy item I recently purchased(and should have done sooner) are the orange soft jaws for the vise. For what needs to be done here, having the ribs held up…

Elevator Horn Shims?

Working on my Elevator Balance Horn and the Lower Horn.  Both of them have a Gap caused by the Center Channel Strap.  I was thinking of inserting a .040 shim in both to eliminate the gap (see pictures in the other post.  Still haven't quite figured out getting them in the same post).  What do y'all think?

My experience with dangers of haze

One area of flying that has very little written about is "haze".There's a lot of stories about flight into IMC that usually center around flying into clouds, rain storms or black hole night experiences. 

However I have learned that haze can be a subtle and deadly situation. The real problem is that aviation weather reports do a very poor job of identifying and reporting on it.

Yesterday was a classic example. I was flying home from Pine Mountain Lake in Northern…

We will fly this propeller to Sun N Fun. Hope it increases the utility of many Zenith planes

A propeller where you can have it all.  

  • Maximum climb for those local flights and grass strips
  • Maximum cruise when you fly from paved airport to paved airport
  • Adjustments are made in a few seconds

This adjustable propeller is legal for all pilots to operate.  No special skill is required and the entire blade rotate to the desired pitch, rather than twisting the…

Speed restrictions of a Light Sport compliant aircraft

So many ask the question of how to build an aircraft that a light sport rated pilot can fly.

Here is the answer to one typical speed question:

The speed of your completed airplane is dictated by it's overall configuration, not the engine. While it is true that Viking would like to show you how fast it could go, it is not true that you will automatically have this speed if you need to comply with a lesser speed.

The pitch of your ground adjustable propeller will give you…

Building Benches

As I have continued on with building my plane and having the space, I wanted to make some more benches. These pictures were made last year. What makes these a little different than other benches is that I decided to make the benches modular. The tables are 4x4 in size instead of the usual 4x12 that is often made. I made a 4x12 when I first started building, but that one has been retired in favor of the 4x4 benches. Even if someone had more limited space, using 4x4 tables could make easier to…

Steel beams for building

Hello all,

 I'm getting ready to build my 650 wings and thought maybe I'd get some steel beams as shown in the guides. 

 Are you all using them? Where did you get them?

 If you aren't using them, what are you using?

  I just used 2x4's for the rudder, stab and elevator.

Thanks!

A few simple tools

Below are a few simple tools I have made that others may find useful.

1. Wooden "gage" blocks- I have all sorts of bits of left over 2x4's. It has been useful to cut those into lengths such as 1",3/4", etc. If I need to elevate part above the table a little bit, I have a good selection of "calibrated" heights to work from. And as can be seen from the holes, they make good backer blocks for drilling. And for those last little bits of tweaking, door shims work quite…

SkyJeep Flywheel Replacement Viking Honda

Found two cracks in my aluminum flywheel.

The new parts require the reduction gearbox to move forward 1/4 inch. This causes the radiator to move forward, and interfere with the cowl.

I decided to try modifying the drive coupling by machining 1/8 inch off each side, thereby recovering the 1/4 inch.

I plan to do a few high power ground runs before flying, and will update this post with the results.…

6,600 mile trip to Central America proves to be big adventure

"That which does not kill us makes us stronger." - Friedrich Nietzsche

Since I started flying my 601 back in 2007 I have found it to be a fantastic machine for exploring and adventure. I have enjoyed expanding my view of the world by flying over the country side, looking out at the great sights below and taking pictures from time to time; actually thousands of them.



In the past few years I have had in mind to fly all the way to the tip of South America. I…
