Brother Hobby R3 1106-7100kv
The higher Kv of the R3 1106 motor line
Mirroring what we've seen in static thrust tests, the 7100kv R3 is pretty disappointing overall. Large lack of efficnecy at lower power levels, and a much smaller sweet spot at high power put it at a disadvantage. It appears to have a general lack of torque as well, so it's not able to maintain it's rpm as well under high loads. At extremely light loading, lighter than a DYS 2030x4, it's extra Kv can carry it a bit further, and it would be better served with higher voltage at light loads than being a brute at high prop loading. It's fairly well matched to light 3" prop loads, but is perhaps a little more closely suited to a 2.5" loading.
