i am having a problem with some whirling recently. i've had my cx2 for 10 weeks and about 40 blades. i recently went to the middle hole and need to go back to the hole next to factory setting, too sensitive in the middle hole. no real mods to speak of (broken/no front plastic mostly). thanks for the experience in here.
Is it violent whirling? If so, You may have your motor wires backwards; not polarity, but the top one in the bottom, and vice versa. (the wrong motor in the wrong connector). Just switch them out.
Will fix it instantly. You can check Your polarity as well.
Kinda need to know more from You.
Good Luck, and Welcome ! !
