Hi,
The greater efficiency of brushless motors seems to be well established. What I was wondering was whether in the real world this translates into less electrical power needed, and therefore smaller batteries, and if so then could any estimate how much could be saved?
To give a concrete example, assume I am changing from a brushed motor driven by 1100mAh 9.6v NiMH pack. I'm going to change to brushless power with a Lipo battery while I'm at it, but I'm doing so mainly to reduce weight and not to increase power. Given the assumed greater efficiency of this setup, what sort of size pack would be needed to get the same sort of duration at the same power as the old brushed setup?
Thanks in advance, Tony S
