I dont think the over square prop will unload that well unless in a dive, I was thinking about putting on the 8X8 and pulling the timing back to 7* Id bet that would be about 700 watts ... I wonder what the stock motor is capable of before it starts to make heat and effeciency falls off .... when I was doing motor R&D I did many 25KW pulls and watched as heat increased how effeciency would fall off. I did get my prop drive 35/36 1800 today ... did you have a plate that will bolt this to the stock mount?
the battery on the tests above was a little low Ill repost over the weekend corrected numbers ... I thought they were a little low.
did a pull with the 7X8 on a fully charged battery 2200 45-90C 4S and got about 560 watts at 30*.... so it might be safe to add 150 watts to the above numbers
the rare bear on a 1000 25-50c 4S pulled just under 300 watts with a 5.1X4.5 spoonie prop
I am not sure what bolt pattern u have on that motor.
