Another possible solution to help with crossing of elevator cables and reduce heavy right stick pressure.

There are a lot of great ideas from other builders and I learn a lot from prior posts. Just passing along how I solved the cable issue for others to consider. It worked for me but each can judge if it’s in their best interest. Posted for entertaining purchases only. “Keep the attorneys away” lol. Like others I realized I i needed to cut the bellcrank off the aileron tube. Before doing so I market where the factory location is for the pivot on the elevator arm /brackets under the center tunnel… Continue

Center Wing spar issue with rear ribs

An issue with the center wing spar rib stations presented when fitting the rear ribs. The spar rivet holes are pre-drilled and the flange on the rear rib is not. I noticed that the top and bottom spar web rivet positions were very close to the ends of the rear rib flange, violating the 3 diameter minimum 2 diameter rule for rivets. I spoke with Roger at the factory. and the top and bottom rivets are useless. As a solution, another rivet hole is added at the top and bottom of the rib station…

Flap/Aileron Construction- Part 1 Test Sections

Scratch construction of the ailerons and flaps has been started. I decided to try to document as much of the construction of these as possible as this should be my last major set of parts to bend. There will be two or three parts to this. In the first part, I document the construction of test sections to verify my CAD drawings are correct.…

TD nose rib gear channel

No easy task.  After a lot of study of the drawings, I totally screwed up the first two gear channel parts and ordered new ones.  I believe I have the left one done; drilled, clecoed and ready to rivet.  I will to wait on the spar riveting, I see some challenges there with the second row of rivets in the rib channels.  …

Matco Rims!

After spending a very frustrating week trying to mount my tubeless  tires on the Matco rims provided I  have given up. The O-rings they supply for sealing the two halves of the rims together absolutely will not fit. Matco say to roll the O-ring over the rim to the flat at the edge of the rim, assemble  the two halves and roll the O-ring back  to the center of the rim and lubricate the O-ring  and you should be good to go. Well this is absolute impossible. the O-rings are to…

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

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.…
