Elevator completed

Today closed up and riveted the top skin and horns.  Rechecked the electric trim with a 9v battery, Not happy with the provided cotter pin attachment to the clevis rod as it appears to me to be hazard should it catch on something so I spent extra time laying it down.  I notice a lot of openings in this design which is an invitation to insects, mud wasp and what have you.  Anyone have ideas in how to fill those openings?…

Elevator trim tab horn issue

I have been stuck working on the elevator trim tab.  I needed to fabricate the horn and install it in order to adjust the servo push rod and ran into a problem with the drawing of the horn.  It does not fit the clevis of the RCS-7 Clevis kit supplied with the CH601 kit.  I worked to modify the horn to fit the clevis, positioned it and drilled ready for rivets…

Zodiac 601xl New Nose Wheel Oleo Strut

Hi, I recently replaced my bungee cord system with the new Oleo Strut. I like it but.... flying it for the first time today, the airplane did not fly well. The ball did not stay in the center. I had to give it constant left rudder. The plane was skidding to the left. (felt like it was out of rigging) I will adjust the rudder pedal cables. Has anyone experienced this? Any solution? Thanks in advance. N602ZA Robert

Super Duty Build

Hi guys and gals, just thought I'd drop a quick post about my 750 Super Duty build. Rudder and tail section nearly complete, I opted for the quick build fuselage from Zenith as I didn't like the idea of attempting that on my own. Let me know if anyone else out there is building the Super Duty, keen to share experiences and support each other through this fun and exciting adventure.…

Oshkosh 2019 - Part One

I was starting to write my Oshkosh 2019 follow-up report, but the highlight of this year's Oshkosh experience for me actually happened after flying home from the event, when I received the following email letter:

"Mr Heintz, from the time I was a boy I loved airplanes. Life, as it does many times, prevented me from becoming a pilot until I was 40 years…

Turbulence damage on flight back from OSH to WA

I’m back from OSH, but had a few seconds of severe turbulence that damaged the plane.  I was flying Zenith 650 about 32 miles south of Big Timber airport (approaching Springtime, MT) in moderate winds and very light turbulence.  Certainly very common in any type flying.  Nothing that bounced me out of the seat.  I was hand flying instead of auto-pilot as the…

Start Drilling Left Wing Skin to Ribs / IV Video Camera Stand

After two or three months of weekends of checking and adjusting, I am finally ready to start drilling the top wingskin to the ribs.

A couple of concerns I have is holes not appearing where I expect to them and also the ribs shifting while drilling. To help catch any problems early, I have setup a video camera that I can place under the skin to watch the rib and hole.

A short video below demontrates the video setup and the drilling of my first hole into the left wing…

Stabilizer complete

Finished the stabilizer today by adding the plastic ribs.  Probably took longer then it should, however, I found an error with the rear spar attachment plate and needed to order a new part, rebuild it.  Beyond that getting the skeleton and top skin to cooperate took practically a whole day until I was satisfied.  Replacement parts for the elevator are in so I will return to that part of the project.…

Elevator and Stabilizer

The elevator is on hold waiting for replacement parts.  Tried to salvage it but it was beyond me.

I moved on to the stabilizer and finished the skeleton tonight.  Skills are getting better.  Had trouble with the hand rivet gun from Zenith.  It stopped working.  Took it apart and removed all the metal dust, oiled it up, and it is working again.  Otherwise, no issues so far with the stabilizer.…

Gear Leg Nut Torque

Can someone tell me what torque value the 4 landing gear leg bolts should be.

When I bought this aircraft (601XLB) one of the 4 nuts was only finger tight.

Glacial paced progress

I recently travelled to PNW to finish testing mod to our fuel system.  We added shut off valves for tanks left & right.  Tested successfully for leaks.  Then put the plugs in and started it up.  First time in several years.  Seems so small but it sure felt good.

CH 750 STOL Rudder Kit - Anybody Looking for One?

I have a "new in box" CH 750 STOL Rudder kit I need to unload.

I bought it from ZAC in 2015 at Oshkosh; then had second thoughts about STOL versus Cruzer, and ultimately switched to the Cruzer, which I'm presently building. It's in its original crate and has never been opened.

I'm planning to bring this with me to Oshkosh in a few weeks. If anyone is interested please let me know. Thanks!

Error repaired

Learned today that I should not trust anything, esp. myself.  Had to remove the nose skin on the rudder as I had incorrectly tucked it under the rear skin when it should have been installed on top.  I have a new skill, rivet removing! Getting real good at…
