Zenith 750 Cruzer, Finishing the elevator

July 30 2023

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,…

Zenith 750 Cruzer, Stabilizer tips

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…

Reply to Jason Zywers

I made a post on this topic somewhere in the blogosphere earlier and now I can't find it.  So, I will try again here.  I am looking at purchasing a circa 1997 "hangar find" Zenith 601 Kit (does not include an engine or the finishing kit).  A local EAA technical counselor who has assisted with two Zenith 601 projects advised me about a wing spar AD.  The wings are complete and in a cradle.  Looking around at all the places I can think of I cannot locate any information on the wing spar AD.  I…

Zenith 601

This is my first post. I'm in the Kansas City, Missouri area and have been to Mexico, Missouri and flown in the factory plane on a demo ride. I like the 650 (low wing) and am interested in upgrading to that kit. I currently have a hangar find 601 circa 1997. The wings and stabilizer are complete, and fuselage is partially finished. No engine. I'll add some pictures in another week once I get everything out of the packing boxes. My Dad and I have built a Quickie (a Rutan design) back in the…

IO-375 cooling - solved.

Cooling the IO-375 -

I’ve got a little over 350 hrs on my 801 with IO-375 now.  I really like the engine - lots of power….. and heat. Piston oil squirters shift some of that heat into the oil, and it can be a trick to manage.  I found myself needing  to make a couple of adjustments along the way to get control of oil and cylinder head…

Zenith 750 Cruzer, A wing storage rack

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.

Drilling the holes under the right angle was the most difficult part.

FAA Releases MOSAIC NPRM

The FAA has released the Modernization of Special Airworthiness Certification (MOSAIC) Notice of Proposed Rulemaking (NPRM) for LSA aircraft. Among other things, an aircraft’s weight limit would be based on stall speed. This could allow aircraft weighing as much as 3,000 pounds to be classified as LSA. The proposal would also expand the types and usage of LSA aircraft, allowing some aerial work. Sport pilots could operate up to four seat aircraft, but would still only be allowed one…

Zenith 750 Cruzer, Riveted the stabilizer top side skin

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…

Zenith 750 Cruzer, stabilizer L angles

July 05 2023

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…
