9XL headache

just temp check the motor and esc often as you test it, a demaged motor usually feels weak and glitchy, especially off the line, and you are right about the airflow, it is important to have the cooling airflow, otherwise the motor sits in a pool of stagnant heat. 35,000rpm should be fine just check temps, and not over 40,000

also, the sealed design of a feigao make them amazingly resilient to water, I do nothing to my motors when I run in the snow, and they are all still running, my buddy dunked a sidewinder in a lake, still running. IMO i'd be more afraid of overheating the motor due to weather proofing than water damage, on the other hand, sensored brushless hears the word water and fails, i'd go as far as to say my MM is "splash resistant" as it has been wet a time or twelve
