prop pitch vs battery time
I have a 400 speed brushed motor and 7 cell 900mAH NiMH pack and 9x7 prop.
If i change to a 9x6 prop or lesser would that increase flying time/battery time or decrease it due to higher motor RPMs? Should it not increase since the motor has less prop resistance to overcome or will it draw more current since the motor will be able to turn faster?
i dont want to change to Lipos as yet
