Steve Goodwin Posted August 31, 2021 Share Posted August 31, 2021 Could someone explain why the higher powered motor is cheaper. Thank you in advance Quote Link to comment Share on other sites More sharing options...
Kim Taylor Posted August 31, 2021 Share Posted August 31, 2021 Is it higher powered, or are you equating a higher kV to higher power, which isn't necessarily so. The cheaper motor is a smaller can length, which would normally indicate lower power (ultra simplistic, I know). The acid test is the maximum amps which the motor windings can operate at and the size of prop which it'll turn. In the case above, the larger kV motor will be limited in what prop you can use, assuming that the same battery is used. 1 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 1, 2021 Share Posted September 1, 2021 Often, item price is set by quantity bought in by the supplier, and their desire to reduce stock levels Steve. I don't think the accountants care too much about the power of the motors. 1 Quote Link to comment Share on other sites More sharing options...
Shaun Walsh Posted September 1, 2021 Share Posted September 1, 2021 If you look at the full specification for each motor, the more expensive one is rated at 125 watts, the cheaper one is rated at 115 watts, so the dearer one is slightly more powerful. The kV figure simply tells you how many rpm the unloaded motor will rotate at for each volt applied to to it by the battery. 1 Quote Link to comment Share on other sites More sharing options...
