HSK90, 90mm sized brushless Whoop

HSK90 FPV Drone

HSK90, is a 90mm sized Tiny Whoop alike brushless FPV drone. The frame is made by two carbon fiber plates. While the upper frame serves as propeller protector, the bottom plate holds the 4000KV brushless motors.

On top of the drone is located the 600TVL camera with 170 degree field of view (FOV). IMHO it is quite exposed in case of crashes. The camera is paired with a 7CH-25mW VTX.
