One Propellor Seems To Click As It Turns Is This Usual Syma X5C

Chosen Solution

It is the last to spin when the drone powers up. It does spin in high power mode but the drone is not balanced and drifts in the direction of the propeller in question when it takes off. The other propellers spin freely, this one seems to ‘click’ slightly as I turn it. This model is X5UC

this is not normal. it more than likely is the propellor hitting against the prop guard
