HTML-код
- Опубликовано: 16 окт 2024
- CH750 Super Duty kitplane build progress. We are finishing the aft Super Duty fuselage and installing the Dynon ADHRS inside the aft fuselage. This continues the build progress on this Zenith kitplane. We are making visible progress now.

Mark, I always enjoy your build videos and the detail you show. Very instructive.
I love the idea of using an angle piece with double sided tape as a stiffener in a non structural scenario as you stated. Great idea Mark.
From the quick glimpses throughout the video, the SD plans are a major league improvement over the Cruzer's. Love those iso-views in the drawings that really help to visualize part placement and orientation.
Thanks Mark!... appreciate your attention to detail and the time it takes to document to share with us!
Love the 15 minute size. Can enjoy, for a quickie. I can review it later when I do the tasks and double check and correct before any drilling.
The video series will certainly enhance to value of your Super Duty when the time comes to let it go. Very high quality build.
I enjoy seeing your workmanship results. You obviously have a great repertoire of skills and techniques, which you have applied in achieving those results. You mentioned remaking the rudder plate if the bushing wore. I was thinking that if the bushing in the rudder plate devloped slop in the future, another solution besides making a new plate possibly could be to drill out the bushing using a drill press, and finishing up with a reamer bit. Of course, that would entail removing the plate from the fuselage. Not a lot better than a new plate, but maybe worth a try. The trick would be not to create a new center reference hole location when drilling out the bushing.
I'm sure there are ways to get the bushing out, but my thinking is that it's much easier to spend a few bucks and just replace it all LOL. Maybe if it does need replaced at some point, I will try to remove it before I buy new parts.
You could use a hydraulic press to get that bushing out if you ever need. Just remove the part, press out old bushing, press in new bushing, good to go.
I would describe those green channels as covers for the "B" pillar with the "A" pillar being the back edge of the windshield same as a car.
Looking good.
Great series. You do awesome work. One question however. Why doesn't Zenith just drill all rivet holes to final size?
Phil-most of the holes are drilled final size. Sometimes it’s better to have only pilot holes when multiple parts get stacked and drilled. Also, sometimes it’s just an error and when we bring those errors to Zenith’s attention, then (hopefully) they update the CNC programming!
Mark, is the super duty kit more refined and faster to build than the cruZer kit?
Mark, do you have video of the "L" angles that you put around the AHRS in the rear of your CruZer? Mine is mounted in the same location and I would like to see if it would settle it down.
G,day from Quarantine lockdown Sydney Australia.
You do quality work: just one question. Do the specific pop pivot numbers on the plan, correspond on the package of pop rivots from the hardware store.
🌏🇦🇺
No. Never use hardware store “pop” rivets on an airplane!
Do you have to run another set of pitot and static lines to the panel for the backup display in your center console or do they just have to go to those modules in the tail?
I don’t have the third screen yet but I believe it does require it’s own pitot/static lines that would be tapped into the main lines. If that’s the case I probably will not install the third screen because I don’t want to run the lines up there. I did buy a Dynon D3 which I may mount there instead.
Hi. I know it’s been a long time since you made this video (#52), but at 7:09 you reference a builders manual that I have never seen. I recently purchased a partially built 750 Cruzer. The original builder gave me the drawings and said the plans were online. I have tried finding the online plans and all that I can find is a page of links to partial plans (such as rudder, elevator, etc.). They are far from comprehensive, and pretty much hit or miss, with not everything covered. For example I can’t find any info regarding cable tensions, torque values, and the like. When I saw the manual that you are referencing in your video I nearly spilled my coffee. I have not been able to find anything like those pages. Did they come with the kit, or are the hidden online somewhere? Should I have gotten something similar with my Cruzer? If so I will contact Zenith to see if I can get or purchase a copy. Thanks in advance for your reply.
The build manual for the Super Duty is very different from the Cruzer. They have updated the manual for the SD, but even that manual does not cover the entire airplane build. I suggest you call the Zenith factory and have them re-assign your serial number over to you, and then make sure you have all the current manuals and plans pages.
I don't like that AHRS mount at all- subject to vibration all by itself due to (not insignificant) mass hanging above the two mount points. Not to mention the bolts loosening up (not likely, I know, but just something that bugs me). Why not a more conventional four point mount, and shims if required?
You can mount yours however you want. The purpose of this video is not to convince you to build your airplane just like mine. This is the same mount I’ve had for a year and a half in my Cruzer and it works perfectly.
What about a bead rolled in that panel ?
where are you mounting the air temp OAT sensor that comes with the ahars.
Im not 100% sure yet. I noticed Zenith had theirs mounted on the side of the forward fuselage.
@@KitplaneEnthusiast I am thinking the belly next to the adhrs
How deep do you think you'll be in to your Zenith? I met alot of people at #OSH who are currently building them. I'm intrigued.
Do you mean how much money will I have into it? I have no idea. If you buy everything new I'm sure it's over 100k.
@@KitplaneEnthusiast yes that's what I meant 😎
Turns out... People with a green thumb are also good at building airplanes.
