Happymodel Sailfly X motor mount frame reinforcement

thingiverse

I am sharing a motor mount reinforcement for the Happymodel Sailfly X that greatly strengthens the motor area after crashes, which are often caused by broken motor mounts. This small and lightweight addition must be glued on with CA or a light weight epoxy, requiring each surface to be sanded before gluing. I have used ABS but also found PLA works well. I designed these parts without holes, allowing you to easily drill them using the original frame as a template. You can either drill oversized holes to fit over screws or match the original holes and use longer 6mm motor mount screws. Be sure not to drill through the center motor shaft hole in the printed reinforcement, as this is crucial for its strength. One design features a pin that locates itself in the motor shaft hole of the arm, requiring printing upside-down with supports needed for the tapered end. The pin may need slight sanding to fit into the carbon hole of the frame, but it's easier to install and places the part exactly where it needs to be. I prefer this version, but it does require some post-print cleaning. The other design without a pin is simpler but doesn't have the same ease of installation as the pin version. To print the other side reinforcement plate, simply mirror the part in your slicer. I highly recommend printing all four at once, especially if you're using the pinV5 version. Printing one at a time can cause the pin to deform before it hardens due to insufficient cooling on my printer, although PLA might be okay. Please share photos of your printed item. This is still a work in progress.
