This motor is run using 2-4 cells that could provide it a potential difference of 7.4 to 15.0 volts. For each volt provided, it generates 1100 rpm in its shaft, and hence propellers. It is quite light, weighing only 70gmincluding connectors. Its dimensions (diameter x length) are 28x36mmand the 4mm shaft supports 7x3 (14.85V) to 11x7 (7.4V) propellers. The internal resistance with this brush less motor is negligible (0.10 ohm) that shows the superiority of BLDC motors. The product is manufactured with utmost care on quality. It is duly checked during manufacturing as well as at the time of shipping it to customers.
