f450 unflyable

Hi, ive read and read, and followed instructions on these problems, but im still getting no where

im using a dji f450 with stock esc's and motors, 10" props, 4400 3c lipo turnigy 9x radio.

i had the naza system on this quad when i got it , flew fantastic in all modes but found it limited, so decided to try what looks a fantastic system apm 2,5.

I can just manage to fly the quad in very calm weather in stabilise mode, but when i switch to any gps modes its unflyable like its hanging from a piece of string on a windy day all over the place like a pendulem effect.

Ive balanced the props, used ear plugs as a cushoning for the apm. but im still not able to fly this thing anywhere near what i see on videos.

im using the latest firmware and mission planner

could anyone help me out please. i have some logs

thanks in advance
