Aclouston Posted May 16 Share Posted May 16 What is the consensus among builders/flyers on making a stronger landing gear for the Long-EZ? Is it more layups than required by the plans? Or does it has to do with the alu. angles being too thin? Others? One member talked about something in a CP, but I haven't seen anything in that regard other than the flox added to remove excessive longitudinal play.

zolotiyeruki Posted May 16 Share Posted May 16 I think @Kent Ashton is using a Cozy gear hoop on his Long-EZ Quote Link to comment Share on other sites More sharing options...

Never heard of such a thing. 🙂 Going from memory, the EZ plans call for using hardwood in the fuselage sides, then the angles that hold the MLG are bolted through the wood. But EZs are flown heavier and sometimes landed hard and the bolt-wood-fiberglass-angle combo starts to work loose. If you want to stay close to plans, I would substitute phenolic for the wood and put an aluminum plate on the outside under the skin. Marc Zeitlin has a picture of a repair in his gallery with such a plate. https://www.burnsideaerospace.com/gallery-of-work The angles are 1/4" thick and should be OK but cracks have been known to propagate around holes where they were drilled for brake line passage. Skip that. I built an EZ using an EZ strut but mounting it between bulkheads like a Cozy. It was a fun exercise but probably not a necessary mod. It think there are pictures in my thread at Kent's EZ Project.

Aclouston Posted May 17 Author Share Posted May 17 Ahhh. The consensus is then to never follow...😆 I scrolled through your EZ project but did not see the actual gear attachment. You may have it in an older blog? Any way I can figure out that it is better supported in all directions. If you have a good pic. I'd like to see it. In the end I think I would stick to the strenghtening of the fuselage sides that you mentionned. Quote Link to comment Share on other sites More sharing options...

sixfivelrp Posted May 18 Share Posted May 18 Here are my plates. Also added steel inserts pressed into the aluminum brackets. Note fasteners are temporary to hold the brackets in place.

Aclouston Posted May 18 Author Share Posted May 18 Thank you all of you. I've just looked at the Cozy blog Zolotiyeruri sent me and Kent's project. I now understand the concept. It seems quite a bit more elaborate than the Long-EZ, yet very very strong. - Wouldn't that be a minus for the long in the event of a landing where you want the main gear to collapse rearward? Wouldn't the pitch moment forward be violent? - Where can I follow the complete blog you sent me (zoloriyeruki)? Sixfivlrp - Thank you for sharing this. Can I copy your mod? If so can you provide details? (plate thickness, glass layup, angles specs) Kent You have used a long-EZ strut. Did you build cozy tabs (45 plies, etc)? If so did you use a similar setup than described in the simpex blog ? Allan Quote Link to comment Share on other sites More sharing options...

Aclouston Posted May 19 Author Share Posted May 19 Thank you zolotiyeruki I really appreciate. I'm currently going through the cozy blogs forwarded to me by Kent Ashton. I'm learning a thing or two... Quote Link to comment Share on other sites More sharing options...
sixfivelrp Posted May 20 Share Posted May 20 The plate thickness I used is .1 inch. The layups are per the build manual and A5 template. Plates are under the bolt heads. Our build page is on Face Book under Zieglers long eze. Give me a week or two and I will upload some pictures from different angles. This is of course my interpretation of the existing scheme.

Aclouston Posted Monday at 12:49 PM Author Share Posted Monday at 12:49 PM Hello Fritz Thank you so much for the pictures. I definitly will incorporate your upgrade in my build (both plates and steel inserts). Your build is so neat! I'm now a follower of yours here and on Facebook. Hope to talk to you someday.
