Default Cabane Attachment

I have a WACO 60 the has a 58 inch wing span that will not fit into my car assembled. The cabanes for the wings are attached with small screws and nuts. Assembly at the field will certainly result in a loss of the small nuts for the screws. It would be nice if the nuts were attached to the cabanes so I could just insert the screws.

What other method can I use to attach the wings cabanes.

The cabanes support about 45% of the weight of the model, which under flight loading can impose stresses exceeding 10 X the weight of the model on any single strut at times.

Without detailed examination its impossible to recommend a change in how to attach the cabanes.

I have a couple of ideas for fast assembly/disassembly but they may not work for your model.

You can glue the nuts to the struts with RC-56 canopy glue to reduce the chance of losing them.

Perhaps you can use these inserts in place of the nuts:

Use with CA or epoxy for extra security.

Here are some photos that show how the cabanes are attached.

Default Rivet Nuts

Anyone tried using rivet nuts or jack nuts for this type of application?

Not that I have seen... but it is a good idea for your style aluminum struts. For wood struts its common to insert blind nuts.

Default RivetNut

Here is how I solved the loose nut problem on the cabanes. They are called "Rivet Nuts". They install just like rivets but have threads on the inside of the rivet. Worked great!

My Ultimate with alloy to ply tongues and the plastic struts to ply tongues - I use small self-tappers. Saves all that fiddling with needle nose pliers with nuts !

Yeah
I found some of those at the local hardware store. Very strong, and very secure. But they do need to be screwed into substantial framework inside your model though. I screwed and epoxied mine, and they were stronger than the original setup.
