After having
drilled out the rivets, we now cut out the original Top Spar Cap Angle (6W3-6) 1680 mm. from the inboard end to replace it with the 1/8-inch extruded angle 6-ZU-1-1, taking care not to cut into the rear upper spar cap (we leave the front upper spar doubler (cap 6W3-2) and the rear upper spar cap (6W3-2) intact):
We position and clamp the new Extrusion…

In our third installment, we drill now drill out the conventional bucked rivets of the top inboard main wing spar, starting where we left off with the top rear skin removed and the top of the nose skin opened:
Remember, I am posting this info to show you how
we installed the Upgrade Package to our Zodiac CH 601 XL. This is not a set of instructions or a teaching aid. I only recommend that you attempt drilling out the solid rivets if you…

The
Experimental Aircraft Association (EAA) website publishes "Hints for Homebuilders" video clips, with some useful how-to building information and introductory info on tools, etc.
Though some of these videos are a little too Sonex-centric (they're neighbors with EAA headquarters in Oshkosh) a lot of the information also applies to building a Zenith:
Here's a sample:…

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…

For those of us who tie down our aircraft outdoors and in the wind (whether continuously or just during an occasional cross country trip), it's important to lock the control surfaces so they don't "flap" unnecessarily in the wind. At the Sebring Expo earlier this year, Juan's Zodiac was fitted with these effective control stops:
Above, two tennis balls are joined by a bungee rope, and keep the ailerons from flapping.
Since this was a…

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…

An Australian builder sent the weblink to the following online article published by

Over the past year we have been testing micro vortex generators (VG's) on the bottom of the STOL elevator. We've been using them on our factory demo planes and have sent out samples to experienced STOL pilots, including CH 701 owner and pilot
Bob Jones (of Alaska).
We manufactured our own micro vortex generators out of .020 6061-T6 aluminum in our hydraulic press to match the curvature of the…

Today was a perfect day to perform flight tests for airspeed calibration of the STOL CH 750 (for ASTM F-2245-05 compliance):
With
Roger flying the STOL CH 750, I tracked his speeds with a handheld radar (just like the police use in speed traps). The unit is actually a "stationary Dopplar radar" with a "conical microwave antenna."
With no…
