While we can throw out guesses, to get accurate information, we need more information:
Are the motors mounted at the appropriate height? How many empty holes in the upper bracket?
What is the WOT RPM's of the motors with the current props? At what load?
What is the make and model of the prop you have. Aluminum, Stainless?
