By looking at their dimensions I couldn't resist to buy a few one to try out how they perform in my Furibee F36.
Here are the plain results running from 4.2V bench supply:
No load current: 60 mA
Consumed current while driving the Furibee's 32mm ducted fan: 570 mA
As seen from the currents above (Furibee's motors consuming ~1A with FAN) these motors are not as powerful as the Furibee's.
The thing can fly, but not as agile as with the original motors.
