This is a big deal for some of the smaller OB cats, and even some single engine applications.
Will definitely help those that are currently limited by prop size.
Quick ghetto math at 7k RPM’s is about a 10 mph swing with a 32” prop and 10% slip.
And hopefully this this is a preview or sign of the bigger HP version of the 300R platform.
