That does make it worry free.Plus, the M5 is so well insulated you probably would not hear a drone like the X5M. But, I’ve verified with a light, if the settings are correct, (can be confusing) they are open at start up and part throttle. There is a trick to cold start. The settings have to be correct and it takes one tap of the throttle to activate. Ask my neighbors,,,,,lol.
