For maximum lift capability, we need brushless motors with low kv rating (kilo rpm/volt) swinging large propellers. We considered two motors for the drones - the first motor running on a 2s battery and the second one on a 3s battery. The second one seems to be more powerful and available from the USA warehouse, so will likely be the best choice.

Installation

Motors screw directly in the frame using the screws that came with the motor (for the 1000kv motors) or with the accessory pack (for the 800kv motor). Do not forget to use threadlock on the screw tips.
