Have CH601HD's with Rotax 100HP engines faired well in cruise and climb performance?

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…

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…

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…

Stabilizer skeletons that is. I've updated my build log. :)

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?

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…

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…
