Mistral Super Light Tail Fin Spring Retainer

thingiverse

The tail fin of my Mistral Super Light would not stay in the down position, due to the spring retainer at the rear broke due to age. This is a replacement for that plastic retainer. If your fin won't stay down, try this fix. The picture shows the broken part in white at the left, next to a replacement piece in gray. A fix is mounted behind the blue fin, you can make out the spring attached to gray plastic. You will need Needle nose pliers to pull spring over the replacement, and then tighten up the screw to hold it in place. I printed it using PET, but other material will work, PET or ABS best probably. I used 30% infill, and 0.26mm layer height.
