This suggests to me, it is best to run a motor with as high as kv rating as possible as not to over rev motor, excede esc Amp ratings, and not to create mechanical heat (fric from bearings, etc) that doesn't exceede that of the gains in efficiency. What that point is IDK, but I imagine fairly high, but you'd still get better runtimes as you are drawing less current for same power output. How this translates to real world would be interesting to prove.

Yeah, a couple places have those calculators, but prop loading is kinda comple and hard to draw parallels to road use, but I see what you're saying.
Did you mean to say "This suggests to me, it is best to run a motor with as
low as kv rating as possible..." judging by the rest of the paragraph?
