FMS 1700 Piper PA-18 Super Cub Wing-mount

The FMS 1700mm Piper PA-18 Super Cub wing-mount posts are prone to breakage - well at least my dad's broke. Unfortunately, the mounts are glued to the foam fuselage and a new fuselage costs $70USD+shipping. Here is a replacement part for the rear-ward post/mount that is thicker and hopefully stronger than the original.

Notes:

• You will need to remove the old post/plastic mounting parts from the foam fuselage prior to install using mineral spirits or acetone to dissolve the glue
• You may need to shave some foam off the fuselage to ensure proper fitment of this part since it is slightly thicker than the OEM part
• Minor sanding/filing of the post corners may be required for a good fit inside the wing cavity
• Rather than embed a brass nutsert like the OEM design, my approach includes a nut-trap so you can drop in an off-the-shelf M3 hex nut and re-use the original M3x16mm bolt. You can glue it in place with a few drops of CA (superglue) or hot melt glue after test fitment of the wing. You'll need to glue the new part on with FoamTac or similar adhesive spray.
• The model is for the left-side (port) - so mirror about the [Z-X plane] it to get the right-side (starboard)
