These were designed by Hyph muiltrotors. They are engineered to meet a couple keep aspects.
They have the perfect hole size length so you can secure the motor with all four screws if necessary.
Attention to detail that the center hole is big enough to clear the c-clip for most motors but not too big for not enough support around the base of the motor.
These still have the necessary compartments for your motor to intake cool air.
With all these things in mind there is material all in the right places to support the motor and provide a nice softmount. We have testing the best amount of softness for the best results.
