Used a strap duplicator to drill holes in the angle without enlarging the existing holes in the skin and the ribs.…

Drilled the top spar. Clecoed the top skin.
Drilled one hole incorrectly. Drilled two additional holes around it using the same technic I used for fixing the holes in the bottom spar.

Drilled holes for the Pitot tube. Used a step drill.
Added angles to the wing top skin. I do not have a room to move the wing from the workbench quickly. I placed the top skin on sawhorses. I decided it would be better to have access to both sides of the skin when riveting. I set the skin vertically.…

Riveted the flapperon arms. All rivets on the arm near the tank are set the blind side toward the tank to reduce a possible interference.
Since I did not set the rivets in the skin near the arms the riveting was smooth. I had not had to remove any rivets to make a room for the rivet tool.…

Leveled the wing. Used a laser guide to level. Much more convenient than a bubble or digital angle finder.

I made an error when drilling the bottom spar. While drilling the skin moved a bit. Because of this all holes in the spar look ugly.
I suspect it happend bacause I tried to use cleco #40. Instead I probably had to drill #40 and immadiately #30. I was not able to set cleco #40 firmly. Cleco #30 was set hard without any problem.
Because of some reasons it took me a very long time to contact Zenith and ask what options I have to fix my error.
It looks like I…

Started removing the wing top skin to debur everything and prepare the wing for storage.…

Zenith sent me a new spar root angle. Matching it to the root top skin and the root nose rib was a difficult task.
I spent several days trying to match them. I have some version represented on the pictures.
I sent the photos to Zenith and will talk to them to decide it the solution is good enough to proceed or I have to invent something different.
I bent the angle several times. I am not sure it is still strong enough. May be I will ordere a new…

The new wider spar root angle does not fit the root top skin. The old one also does not fit.
The top of C75W4-2 Root Rear Rib is not flush with the spar top and with the Spar Root Angle. It corresponds to the drawings. The spar end height is 80mm and the Root Rear Rib front end height is 91mm.
Since the tops are not flush there is a gap between the Wing Root Top Skin and the Spar Root Angle.
The first two pictures show the spar and the Root Rear Rib are…

Making the C75W7-6 root top skin angles. The drawings has 2 pictures with them. On one picture they are straight. On the other picture they are curved.
Zenith says they should be curved.

Cut the C75W6-5 Wing Root Angle in two. Bent using a flute pliers.
Making the correct nose angle was the most difficult.
Made a 40x80 extender which goes toward the trailing edge.
Used a strap duplicator to drill holes in the root wing angle and not to enlarge the existing holes in the skin and the rib.…

The the C75W3-5 Wing Root Angle is incorrect. May be Zenith will send me a new part.
The kit has incorrect the spar root angle. The drawing says the flange should be 25mm wide. Mine is 20mm. The predrilled holes in the root skin are too close to the edge. Zenith is thinking how to fix it.…

September 26 2023.
Clecoed the top and the front skins of the right wing. Used ratcheted straps as the assembly manual says. Tried to do it by hand but failed.

I finished building the workbenches for my CH750 Cruzer project.
I built two of them – 8’ L x 4’ W x 34” H – that can be bolted together end-to-end for a total length of 16 feet. I took a hint from EAA’s Charlie Becker, and put flip up/down casters on each such that the benches are easily rolled around on the concrete garage floor, either when separated, or bolted together.
Just a few more items to procure, and a few more tasks to perform, and I can finally…

Last weekend, on September 7 and 8, the nationwide meeting of UL 2024 pilots took place at the Łomża Jeziorko landing site in Poland. After the conference part, in the afternoon, it was time for practical flying activities. A gate was prepared at the landing site and anyone willing could demonstrate their piloting skills. The pilot's task was to fly through the gate marked out by foil tapes raised on poles and not to break any of the tapes when flying between and below the tapes.
The…

I picked up the kit from the local shipping terminal on December 23 (Merry Christmas, indeed!)
The reserved 16’ Penske rental truck was unavailable, so I was provided a 22’ version at the same pricing. My son drove the truck down and back without incident, and I had four members from the local EAA Chapter 309 to assist with the offloading.
We were able to slide the roughly 14’x4’x2’, 825 pound crate down the truck’s ramp onto two furniture dollies, and push/roll it…

I recently flew down to Robinson (8I1) an unpaved public uses airstrip along the Ohio River in southern Indiana. Nothing special, but another addition to the places I have landed with my CH750 STOL. There is a short YouTube video Pirep at Robinson (8I1) video Pirep …
