Like I stated before, default values for JJRC JJPRO P175 are flyable. But there is a huge difference between flyable and flying good.

I’ve spent few LiPos trying to make it fly just better than on stock values, and here is the most important fragment of CLI dump from my short tuning session.

Changes:

• OneShot125 enabled
• Gyro filtering improvements
• Lower P gains
• Lowered D gains
• Raised I gains
• Raised Rates

feature ONESHOT125set i2c_highspeed = ONset gyro_sync = ONset gyro_sync_denom = 8set gyro_lpf = OFFset gyro_soft_lpf = 90set p_pitch = 32set i_pitch = 49set d_pitch = 18set p_roll = 32set i_roll = 45set d_roll = 18set dterm_cut_hz = 80set rc_rate = 90set rc_expo = 65set rc_yaw_expo = 0set roll_rate = 70set pitch_rate = 65set yaw_rate = 55

Important: those settings apply only to 4S batteries. On 3S PIDs will be probably too low!
