I'm right there w/ you on the Kippawa prop. You have to watch as factory will not warranty if you use this prop, but it is the finest prop on the market IMO. They are pitched more and reportedly will run as fast at 1/2 speed as you normally do wide open. This related into less battery amperage draw. They will also increase control and make for smoother turning. Just a thought, but great props!
