So when I understood it correctly then a lower kv (2300kv) motor and its higher kv (2600kv) brother should have about the same grams per amp up to the point where the lower kv motor gets to its limit because it gets less efficient towards the end of its power curve?!
It varies a bit from motor to motor, but the N52 magnets have pretty greatly equalized things in this regard. They show a good deal less efficiency loss in terms of both RPMs and energy as KV rises compared to the older generation motors. If you look at the data though (on the ZMX 2206 for example, since I have all three KV) you'll see on the same props at roughly the same thrust numbers, they are typically hitting roughly the same current draw until they get to the top 15% or so.
