Tim Donald Posted July 17, 2022 Share Posted July 17, 2022 I've got an electric war bird with a 4 blade 10.5 x 8 prop. I want to change this to a 2 blade, can anybody tell me what size I should use? Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted July 17, 2022 Share Posted July 17, 2022 I would think at least another 2" diameter and the same pitch, test with a watt mater, before and after. 1 Quote Link to comment Share on other sites More sharing options...
