You guys are kind of killing me here... New motors?? The stock motor will handle WAY more prop than this... The 645 only has 2.835" of pitch... The 447 only 2.598"... I ran a Prather 230 on mine and the motor temps after 6-laps on an offshore course were 117-degrees... that's 2.992" pitch... and I feel it's only scratching the surface for a race setup... Diameter might end up being an issue, but if one knows how to pitch up props, I'd start bending on an X645 or similar and see what that will do pitched up to 3+" of pitch...
Of course, if you are just bolting on props, then a new motor might be better, because you can get the RPMs up, which will make up for the lack of pitch in the prop...
