Struts ...
 

Hi,

I have this old Bud Nosen Aeronca champ that I purchased. I has struts on it, something I know nothing about
relative to RC planes.

Can anyone ID what make these are?
Is there anything missing?
When I lift the model, the bottom picture is the result, why?

Thanks!

Hi,
It appears to me that someone tried to make the gear / struts from scratch and gave up.
Most struts have a torque link design that keeps the ram (the rod with the nylon sleeves) in the main tube.
Check out the drawing in this link and you can see what I mean. How to lock the ram into the tube looks challenging. Not sure how Id go about that.

Is there a spring in the upper tube? Im guessing no.

Your shock absorber is missing the bushing that guides and retains the stem; and may be the internal spring as well.

That bushing should be fixed to the cylinder with a rivet, or glue or any other means.

Check the schematic:

Just took a closer look at these. There is a spring in the upper tube covered by another piston.
It looked like if a slide everything up into the tube and put a rivet or small screw in the bottom
bushing they will work!
