<p>The <a href="http://www.fmsmodel.com/fms-1700mm-67-piper-pa-18-super-cub">FMS 1700mm Piper PA-18 Super Cub</a> 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.</p> <p>Notes:</p> <ul> <li>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</li> <li>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</li> <li>Minor sanding/filing of the post corners may be required for a good fit inside the wing cavity</li> <li><p>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.<br/> -You'll need to glue the new part on with FoamTac or similar adhesive spray.<br/> Reference Links:</p> </li> <li><p><a href="http://www.fmsmodel.com/fms-1700mm-67-piper-pa-18-super-cub">Plane</a></p> </li> <li><a href="https://youtu.be/FGjkVs-NgnQ?t=99">OEM assembly video</a></li> <li><a href="https://www.rcgroups.com/forums/showthread.php?3132109-FMS-1700mm(67-">RCGroups thread</a>-Piper-PA-18-Super-Cub/page42)</li> </ul> <h3>Print instructions</h3><h3>Category: R/C Vehicles Summary</h3> <p>The <a href="http://www.fmsmodel.com/fms-1700mm-67-piper-pa-18-super-cub">FMS 1700mm Piper PA-18 Super Cub</a> wing-mount posts are prone to breakage - well at least my dad's broke.
