there is no specific setting angle to the reciever pots for adjustment, Its something you have to tune with trial and error. I have found it best to first work with the gyro gain, Crank it up a little at a time until the tail wags, then back it off 1/8th of a turn at a time after powering down, until the wagging stops. if your heli is spinning try and compensate as best you can with left stick lower trim for now. After you feel confident all the sporadic left right movements from the gyro are in check, then you need to add throttle and notice which direction the heli favors, when ya give it throttle and the nose wants to favor right, that means the tail is blowing too hard and the proportional needs to be backed off.. and visa versa, remember.. small incriments, its sensitive, the better you fine tune the settings, the more predictable the helicopter will become..
