Just got of the phone with Darryl @ Warp Drive. I initially used their online quote form to get a price on a 5 bladed prop. Because if your building a Seafury you gotta have a 5 bladed prop. RIGHT? Anyway, the response from HoverHawk Corp that sells the props was that its too heavy and they quoted me a 3 bladed prop for an O-235. After calling the factory I am excited to say I am still good to use a 5 bladed prop. The Sensenich used was 24 lbs and the 5 blades with hub will be about 20 lbs. SO the plan is to start with 60 inch blades and cut them down from there as I experiment with the performance. I suspect I can go as small as 52-55 inches if need be. It will not be my daily flyer but when going to an airshow the 5 blades are the choice for sure.
