I am considering converting a Hanger 9 62 1/2 in wingspan Cessna over to electric. It currently has an OS 46 Ax in it. I don't like the mess of glow fuel so I am considering the conversion. I purchased a Turnigy L5055B brushless outrunner rated at 600kv. The plane will weigh about 7 1/2 lbs with the big 6s 22.5v lipo. Since the rpm will be, 22.5v x 600kv=13200rpm swinging a 12-8 and using a 70A ESC do you thing this is the correct set up or should I go to the smaller 18v lipo which would reduce the rpm 10800 and lighten up things about 1lb? Is my prop size and plane weight about right, what would you recommend? Is there a conversion chart that a begginer can use that is fairly easy to understand? This coversion stuff can be a little confusing. Thanks for any info you can give.
