Just completed test flights after top overhaul. High flow valve lifters with improved upper oiling system was a easy but expensive change to our a/c. New piston were added as well.
Reinstalling connecting rods went very smooth and neat. Cylinders were reused and new through bolts were…Continue

The following article was published a few years ago in Kitplanes magazine. While all of us may not agree with all of the author's observations, it's shared here to help Zenith builders, owners and pilots increase their awareness of safety issues in operating their homebuilt kit plane. We invite you to share your comments below.
Last month, Roger, my brother Mat and I visited Buzzy Devoll of Buzzair Flight Academy located Carson City, Navada. Buzzy and his wife, Aumie, operate the full-service flight school with a nice new Zodiac CH 601 XL-B S-LSA trainer which is available for flight training, check-rides, and aircraft rental for flying in the scenic area around Lake Tahoe.…
After the January workshop I am now the proud parent of a bouncing baby rudder! It may not be cosmetically perfect, but I would be willing to fly with it. I learned a lot at the workshop, and had a chance to fix some mistakes w/o it being a disaster. The basic skills were easy to pickup, and it was helpful to have the Zenith folks nearby for questions. I pretty much feel like I can build a Zodiac 650B. The biggest challenge is probably clearing & heating the garage and setting up a…Continue
After noticing my nose strut sticking up thru the top of my firewall a little more than usual the last couple of flights I contributed to normal stretching of the bungee 65+ hrs on the plane a closer look I found the cord had about a 1 inch section on the left front than was only about 5/16" thick original is 5/8" the outer covering was in good shape the rubber inside had all but broken. Has anybody else had a problem like this with…Continue
We recently had the chance to give Steve Flattum the opportunity to test fly our factory demonstrator Zodiac CH 601 XL B (upgraded model). Steve flies for one of the major US airlines and has logged more than 20,000 hours. More importantly though, he has a passion for light aircraft, and he has flown more than 100 types of aircraft (from ultralight to supersonic) and performed more than 20 first flights. He holds a professional pilot degree and is a… Continue
Today's flight comes after the downtime of installing the Zodiac XL upgrades which we've been chronicling here over the past five or six weeks. All of you that have been following this series will agree that the upgrade package kit that we… Continue
We've re-installed the flaps and all the controls in the aircraft, as well as reconnected all the wiring and fuel lines.

The aileron upgrades consist of three separate items: Aileron gussets (65W2-5 and 65W2-6) on the aileron ribs, L-angle stiffeners for the aileron trim servo, and finally, aileron mass balance. Above, the right aileron is shown. Below is the left aileron.

Again, I want to thank Doug and Lori from Quality Sport Planes for organizing and hosting the free "Upgrade Workshop" this past weekend at their facility in Cloverdale, California (shown above). This was an excellent opportunity for Zodiac XL builders, owners, and pilots to learn about new upgrades, and how to install them. For more information, contact Quality Sport Planes at… Continue
This is an easy job with the top rear skin removed. We trim the L-angle piece to length, pre-drill it, and then drill and cleco it into the bottom rear skin:
We'll share the position measurements and exact details with the final drawings. The Upgrade drawings are nearly finalized (which will allow us to then release and… Continue
We'll be replacing the original rear wing attach plate (6B5-4) with a heavy-duty 1/8-inch 6-ZU-3-5 Attach Plate. This is the plate that sticks out the sides of the center fuselage and that bolts to the wing's rear channel. Note that the… Continue
