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.
