Slim Phast 4" Shark Fin - Short & Medium Versions

thingiverse

These are top plates with shark fins for the RC Crazed 4" Phast drone. They should greatly enhance your drone's durability if used in conjunction with the original top plate. A comparable shark fin available for purchase measures about 44mm tall, but unfortunately I've witnessed it break a couple of times. The shorter option here is approximately 20mm tall, while the medium one stands at 30mm tall. They should be tall enough to enable your quad to flip over and land safely in turtle mode when it lands upside down. These shark fins do not have an exact fit to the top plate, but they are very close. The orange fin visible in the images is a genuine product from rccrazed.com. In those pictures, the black one is made of PLA and the orange one is constructed with TPU. PLA would be extremely stiff, making it ideal for the short shark fin which can likely withstand crashes without breaking. However, I believe using TPU would be the better choice for this particular fin. The center screw hole spacing measures 30mm side-to-side and 40mm front-to-back.
