KV / Gearing choices

[Dafni]

See? :005:

I remember that thread very well. It's about the size of motors, what they pull and how much they have to work... not much to do with my question.

Here it is again, more specific: Given the same voltage, same motor-size, and adapt the gearing for the same speed, what would be a better motor: low KV (with low FGR) or high KV (with high FGR) ???

And, please refer to my first post too. I'm too lazy to type the "most efficient rpm range" thing again.

I'm just looking for real life experiences: Such as "I have tried this motor, then I bought a hotter motor, but geared down, and my temps got cooler"

Thank you
Daf
