Hello everyone Today I receved my brand new P3A, It was replaced by P3S. It has new motors and GL300C remote. I have successfuly update aircraft to firmware v1.6.0040. There was no need to update RC, already on latest version 1.5.7. I couldnt start my first test because of rain today, hope tomorrow will be better. I just run motors inside without props and when I push throttle speed goes normal up and when I release stick to neutral position and there is some noise. Can't describe, its not loud, like something is braking the motors. I think there was no sound like this on P3S. Hope everything is fine and this is normal sound?
