An F-1 customer with the 3 blade Rocket propeller says the 4 blade MT Rocke t propeller is 2 knots sower at 4,000'. But faster at 9,500' and 10,500'. John. I know this doesn't work for your typical flight. The highest altit ude you reach being when you climb to pattern altitude. :-) Jim Ayers -----Original Message----- From: John Harmon Sent: Sat, Dec 4, 2010 9:32 pm Subject: Re: Rocket-List: Best Prop for HR 2 But it sucks for performans Sent from my iPhone On Dec 4, 2010, at 8:31 PM, Jim Ayers wrote: Hello Rainer, The quietest propeller is probably the 4 blade propeller, MTV-14-B/190-59b with a 76" diameter (190cm diameter).
