Today I plugged a Kv=710 RPM/V motor into the 550.
The heli was a bit lazy, it doesn't reach enough headspeed on both 14 and 15 tooth pinions, especially at the end of the pack.
The motor runs considerably cooler than earlier the Scorpion 4025-1100, and the 80 A ESC gets barely warm. And that after flying a whole battery pack only tictocs. Hmmm it was lacking punch, more like tiiiiic-tooooooc
In a week, I'll do the same again with a 17 tooth pinion, which I ordered today.
Why? It feels stupid to waste half of my battery for heating that Scorpion motor. Yes and oiling the bearings gets old...
I'd love to try the Neu 1907H-1.5Y, even though the specs are probably a bit understated, 1.2 kW only (in the 450 I run the 1107 WAY beyond specs and it survives).
