You will not find out who made the cheap motors and will not find any spec's for them. They were probably originally designed to open and close the tray for a CD or DVD.
Simply buy one for about $10.00 and test it yourself. My first UM P-51 motor lasted about 1 hour. Its replacement motor has lasted about 100 hours and still works perfectly. The brushes wear out after a few hundred hours.
In the UM airplanes the motors drive gears so a bigger (more thrust) propeller is used. You can buy the motor with a gearbox for $13.50.
