Further to my entry on f3b electro set-ups, I had chance to fly my Extreme today with the electric set-up. Below is a graph of the power, which shows that peak power is over 1.5kw. It's a bit hard to interpret the graph as castle creation speed controllers logging is continuous. With soaring gliders the motor is only on for very short periods relative to the length of the flights. By way of example I had a 25minute+ flight with my Xplorer 2 electric off under 20 seconds motor run. Needless to say the graph of the log from the ESC is not that useful. It would be much nicer if the ESC only logged data when the throttle was actually on. The downs on the graphs are more to do with the speed controller settings which brake the motor quite slowly.Anyway, I did a couple of short test flights to get some figures. These show the peak power is 1.5kw on a 17x13 prop, with a castle creations 100amp esc and sloperacer geared inrunner. The Hub is 28mm IIRC.
