Motor Life Expectancy

My P3S now has 124 miles on it. How long do these motors actually last. I have spares on hand but would hate to be on a Litchi run and have one fail. Any assistance would be greatly appreciated.

Other than bearings, the motors have no wearing parts.
So they will last hundreds of hours typically.

The best way to frequently audit bearing health, besides noise, is to measure post-flight temps with your fingers. They should all be similar.

No need for exotic tools unless you already have Laser thermometer on-hand.

From reading posts for years, it seems there's a much greater chance that some other fatal error will occur to kill your AC besides a failed motor.

Great to know, I was wondering the same thing.
