I'm working on a STC for a 4 blade prop for the 337.
Here's a picture.
Electric pitch control, with automatic sync'ing of the front and rear props. Also, you have 4 "common" rpm buttons that allows you to pitch both props to your favorite rpm with one button. Price for both props are looking like they will be around $18K. A little less than the MT's. They are going through vibration testing now, and having the installation documentation written up.
Also, manual pitch uses the same stock levers.
TOTAL install weight is 33lbs front and 32.5lbs rear.
