Hexacopter Blues- failure to fly!

Following my post “Throttle run away on minimal throttle input”. I still cannot resolve the issue. Having tried 3 different versions of the Copter firmware and no luck.

Does anyone in the community have a hex flying successfully on Copter 3.3 with similar specs to mine?
"I have self-built a hexacopter with the following specs:
Emax MT2216- 810KV motors
Spider 20A ESCs re-flashed with BLHeli Blu20A firmware
Pixhawk clone flight controller
Turnigy i10 Transmitter and receiver running PPM, plane mode"
If so please upload a successful flight log so I can analyse the parameters used.
There was a suggestion that the hex firmware may have a bug…
