Question about Motor sizes 4074 vs 3674

[Howard]

Hey Guys,

4074 vs 3674 2200KV motors

Can anyone tell me the difference (besides the can size) between using a 40 size can vs a 36 size can. Considering the KV size the same and the power input the same 2 -2S batteries. Does the 40 size run cooler? Can you put more cells to a 40 size?

The 40mm motor is heavier so it can handle a bit more heat. It's larger diameter means larger magnets, more wire, and more torque - which means more ultimate power. In a small/light-for-voltage hull the 36mm motors are fine, but in larger hulls the 40mm motors can have an advantage by spinning larger diameter props. Judging a motor's horsepower solely by the watt input can be misleading, just like using Kv as the only comparison can lead to very wrong conclusions.

Would a 3674 can offer more run time over the 4074?

Way too many variables for an exact answer to that question...........................

26" cat with seaking 180 esc, 6s and m445 prop. If i changed the 3674 1700kv can for a 4074 can of similar kv would my run time be reduced and how much roughly?
