Say sustained watts closer to 500. I'm guessing/looking for similar KV of 1350 to keep the prop size the same. I know, asking a lot!
I've been searching around but can't seem to find one. Motor specs are all over the map and it seems tips from experimenters work best.
If you want to increase the power substantially, you have to increase the prop load one way or another -- pitch, diameter, number of blades. Or you have to spin it faster. For sure this isn't going to work with 3s and 1350KV as it's only going to give you 12K or so. A 4s setup should give closer to 16K.

The other thing to consider is that going beyond about 350-400w may need heavier motor wiring than is installed in there now as at 500w you will be pulling around 35A. Changing the wiring could get difficult.
