The Octo that i've constructed weighs roughly 4kg, with motor to motor distance of 1 meter, with 12" props and is able to lift off at 40% throttle. However, during the PID calibration testing (fastening a pole along one axis), i'm unable to control the roll and pitch (even at max control). Due to a low CG, it seems to be able to auto-stabilise. Please advice on the possible issues and what further details are required to be furnished. Thanks.

You mean "unable", instead of "able"? If your CG is too low, that really does limit the amount of torque that can be applied at the motors. One thing I would suggest is to either raise the CoG or use longer arms to enable the motors to able more torque.
What are your Stabilize and Rate PID settings? That is the most likely cause of your problem.
I also wonder if you have your mechanical stabilizing pole on the wrong axis? ie: it is stabilizing the axis you are trying to control.
