I ended up not going with an electric jackscrew for the Catalina landing gear. After studying the manual I could not see how the helper spring was going to work very well with its weird angle change over the throw of the handle, and the builder never installed the spring plate to the floor of the plane so I did not have a mount for the other end of the assist spring. So I had an idea. I ended up using a used but not worn out landing gear bungie cord to provide the assistance. It works amazingly well! I am actually blown away. With the wheels off the ground, the lever is EASY to move from wheels down to retract and back. It will be no problem whatsoever in flight which was a big concern for me. It's so easy to move back and forth that I see no reason for electric retract. The assist is very strong and consistent because the percentage length change in the bungie is minimal so the assistance force throughout the range of motion is consistent and comes from the right angle throughout the range of motion. The bungie is completely out of the way when floor boards and seat panels are installed. A picture is attached.
I also completely rewired the Catalina and everything works except the tach which I need to sort out. Replumbed everything replacing all lines and leaky valves and primers. Started the engine for the first time since I have owned it and it runs beautifully (except for tach not working) And last but not least finally got the registration transferred to me and am in the process of getting the operating limitations updated for phase one fly off from my local airport.
So after years of inching along the ball is really starting to roll downhill towards the finish!

NEWBIE

29AUG2023- Hello, I purchased my Cat in 2016 from a guy who got it from another guy. It has the wings complete, the stick controls, fiberglass nose, and landing gear. I have some questions for the group
-Has anyone modified this beast with suspension?
-Has anyone built their own gullwing doors?
-Does anyone have any schematics for alternative engines such as the Viking Honda?
I'm an igloo-dwelling, beaver eater up here in broken-toe Ontario Canada, and always wanted one of these critters, alas 911 struck and everyone bailed out of building airplanes so I built a Murphy Maverick which I just sold. It's time for the Cat to get built.

The main way to increase thrust at launch is to increase the dia. That's why we supply Jabiru with a 2-blade propeller with extra strong 63.8" diameter saber blades. It provides optimum start, flight, noise and engine cooling. At the same time, we have made several dozen wooden propellers for Jabiru to improve launch performance while maintaining cruising speed and low noise. We had to use a special blade profile. The diameter was increased successively up to 68.5". We did not need high speed, our airplane did not fly faster than 200 km/h (124 miles per hour). The propeller continued to "whisper".

I shipped a single Kitfox 2 landing gear from Mn to Or a couple of weeks ago with UPS. The box measured 14 x 14 x 33 and weighed 10 lbs. Shipping cost was $92.53. The guy at the store redid it three times because he couldn't believe it was right either. It was right, but for sure seemed all wrong. JImChuk

This thread is getting old in the tooth, I would have thought he would be getting tired of moving them from place to place in the shop by now. I'm still looking for a set like those but don't want to pay the postage from California.

Funny deal there, I had a Sensenich 2 blade ground adjustable prop for a Jabiru, and ended up selling it the Sam Rutherford. Had to ship it to England as I remember. Never heard from him after he got it. I think I remember reading the plane got wrecked at some point after that. He had some kind of adventure company, and they did some pretty wild things. I just googled him and pulled this up among other things. JImChuk

What did you figure out with this. I have a mk4 jabiru with a fixed pitch prop. Just wondering where this went?

Sorry, moderator of the site, it didn’t show his ad going up on the Internet so that’s the reason why I push the button a couple times and unbeknownst to me.

Sorry again sorry again.
