Riveted the elevator.

My riveter head is too large to get inside the cradle. I used a nut as a shim between the rivet head and the riveter.

Tuned the servo. To make the range +20 -40 as per the drawing I had to set the distance between the trim arm pins to 119mm. Very close to the recommended 116.

Changed the way the safety wires on the piano hinges are set. It is the way the safety wire is set on the Zenith demonstration plane. See the last image,…

Riveted the stabilizer tip ribs. Drilled the stabilizer tips. The angle between the tip rib and the stabilizer is good enough I believe.…

July 27 2023

Sanded the plastic stabilizer tips to make edges flat.

By a reason I cannot understand the parts C75T1-11 tip rib do not have predrilled holes in my kit. The Assembly Manual assumes they should be.

I send an email to Zenith and talked to Roger on Oshkosh.

Yes, it is an error. The holes should be there. But instead of asking Zenith to fabricate and send me the new parts I decided to drill them. After all it is a part of fun.

I draw a 10mm line from…

July 22 2023

A storage rack. It was designed to keep the wing. Since I do not have the wings yet I store the parts already built. It has enough room for the wings too.

I used a right angle drill extender from Harbor Freight.

Cut, drilled, trimmed and installed two L angles.…

Matched the stabilizer and the elevator with a piano hinge. They move not quite freely but better than I expected.

Started building the elevator weight balance arm.…

July 8 2023

Riveted the stabilizer skin. User ratcheted belts to close the skin. Much more convenient than to push by hand.

Almost at the end I dropped a drill bit inside the stabilizer through the rivet hole. The stabilizer is fully closed the there are no holes I could get the drill bit. I did not want to leave it there forever and rattle. On the other hand I did not want to remove a lot of rivets to get it out.

I used a wooden wedge to make a small gap between the skin and…

Made L angles to attach the end ribs to the spars. The drawing is incorrect. It says to make 56 and 60 mm L angles. They are too short and do not fit the predrilled holes.

The assembly manual is right. The length of the L angles should be 75 mm. I used a long drill bit to drill through the spars. My electric drill does not fit the space.

Attention. I clecoed the ribs incorrectly. On the pictures the rib goes over the spar. The ribs should go between the…
