Five33 Switchback HD Turtle Fin

thingiverse

This is a reinforced/braced turtle fin for the Five33 Switchback HD Frame. The Switchback HD frame has wider mounting screws in the front for the top plate versus the original Switchback frame so many of the existing designs will not work on the HD frame. Additionally, the existing fin design from Five33 made for the Switchback HD frame looks great but in practice, it is too flimsy. When the weight of the drone and battery is on top of it upside down it usually folds over defeating its purpose. This design has two small braces to prevent that problem from occurring, while still being as lightweight as possible, and limiting the air resistance across them while in flight. Don't mind the dirt on the fin, it is there because it has been used and it works well! Printed at 0.30 layer height, supports are not required.
