Thanks guys for the prop help but aquaskiman, you said you recommend a 12.25X3.75 prop yet if you calculate its Propeller load factor Diameter(squared) X Pitch the props plf comes out to 562 and yet they recommend something near 800 for the 46Fx or lower , but isnt the 562 plf to low. If you look at the nomograph that displays what speed youre prop can put out with what rpms you have (im using 1200 rpms on the scale because I think thats what my os 46fx should put out) the chart says the 12.25X3.75 can only get the plane to go 60 mph. Is the aresti airframe designed to go faster because most people have recommended the 11X6 for me which has a plf of 726 and will push the plane 80mph and the 11X7s plf is 847(might be a little high) and pushes the plane 100mph,, im really not sure which prop to use now, is youre 12.25X3.75 making youre plane go good good vertical and good acceleration but low top speed compared to the 11X6?
Thanks for any more info u may give me,
Thanks a BUNCH,
Andrew
