Thank's chipped prop. Did you sand and fill before monocote? or just go over everything as is? I was thinking about adding some ca hinge's to reinforce the existing foam hinges on the elevon's.
My understanding { maybe i'm wrong} is that to get extreme speed's you need a low pitch little bigger prop to overcome wind resistance. I'm running a 4.75 x4.75 on my 120 mph funjet now , but i wonder how much cavitation i'm getting and losing efficiency. That's why i was thinking about a 6x4. When I watch you tube vid's it seem's to be the prop of choice...Thank's again
