Motor selection

I am trying to choose between these two motors for a four wheel drive robot. Does the propdrives higher max amps make up for its higher kv in regards to torque ? How do I calculate the lowest rpm odrive will be able to turn these in velocity mode ? If anyone knows of any other motors that are relatively short ~40mm and also low kv please let me know.

turnigy-aerodrive-sk3-4240-530kv at 14.8V 7844rpm max 46a

propdrive-v2-4238-750kv at 11.1v 8325rpm max 55a

Make a copy of this file for your own use, and put your motors in. It should help you solve the dilemma :slight_smile:
