After auto tune my quad's PIDs were lowered to such an extent that it couldn't able to resist slightest wind. For example Rate_P for roll & pitch was adjusted to 0.04 which is too low. The default params are OK for flying, little tuning of Stab P, Rate P & I is required which can be done manually. And yes there is the option to revert the auto tune values.

@anis, did you checked the motor connections and props ?

As mentioned above check your motor direction and props.
