FPVWRA SPEC - Motor Mount

thingiverse

I designed a FPVWRA spec motor mount that fits a thinner profile wing with a root thickness of 1 inch, which is the minimum specification for such wings. I built this mount using pink rigid foam and hot-wired it into shape. The goal was to minimize any airflow disruptions caused by the motor's presence on the wing, so I extended it about a quarter inch from the trailing edge of the root aerofoil. To secure the motor in place, I added grooves along the profile that snap over carbon cross spars located about 20mm away from the trailing edge. This design ensures a snug fit and maintains structural integrity. The total weight of this motor mount is approximately 14 grams, which is impressive considering its functionality and durability. I'd appreciate any feedback on this design and am open to modifying it if you need different specifications or mounting patterns.
