Motor question

[cool][#0000ff]It's a combination of basic physics and minor engineering differences. Theoretically it should take the same amount of power/thrust to get your craft from point A to point B...regardless of how large the motor is. But because some motors are designed to operate more efficiently at higher speeds...or lower speeds...there can be a difference in how much juice is drained from the battery with two different motors moving you the same distance.[/#0000ff]

[#0000ff]Even with the same motor there can be variables. If you run your motor on high speed, you will get to your destination faster. But if you run it at lower speed you get there just the same...and usually with less battery consumption.[/#0000ff]

[#0000ff]There are also the variables of propeller size and pitch, power to heat loss, drag from anything dangling in the water, etc. And don't forget ambient temperatures. Running a motor in cold weather will run the battery down faster than in warm weather.[/#0000ff]

[#0000ff]A 40 is plenty for most applications. But spending a few dollars more for a more powerful motor might be appreciated when you have to fight back against a stout breeze.[/#0000ff]
