Pilot Error or Builder Error?

Hey fellas!

I'm building one of those Vtail Bat Bone quads from Flite Test. It has a NAZE 32 board that is flying in Angle Mode. Gains are all default. Transmitter and radio are all working just fine, props are all spinning the right way ... and I think everything should be good. I can fly the simple quadcopters and learned on the Ominus Dromida just flying round the house...so I CAN fly in a manner of speaking I suppose! :)

But my build starts to spin horizontally about the yaw axis. It is uncontrollable. I took it apart (again) and the only flaw I found is that the inner black prop hubs were a little too large. Could this cause the spinning in your opinion? Are there other culprits to look for? The ESC's all seem to be calibrated and the motors all seem to spin properly. I am thinking this is some kind of blatantly silly problem...
 
Hi mate are all channels zero in base flight if the radio gimbal is sending a signal this will turn the quad , so plug into base flight go to monitor screen and see if an input is being received by the nase, if it is zero this but using sub trims in the radio
 
G'day mate - are you an Aussie? I can hear an accent of some form right over the internet! :) I am a hosehead from Alberta in Canada!

I am running the Cleanflight utility and have watched several vids on setting them up. The gains all look right, the receiver outputs correspond to those spelled out on the Flitetest tutorial...about the only thing I found was that the prop bushings were too large. Could the gains in the radio be at fault? Whatever it is - it only affects the rudder channel...
 
It could be the gains in the radio, or you could need to trim it until it is showing zero in for the FC (basically what @holtneil said)
Here is a video where you can really "hear his accent across the internet". :p

A quad turns CCW by the CCW props spinning faster than the CW and so on. here is an image to show that.

No I am not an Aussie, would love to be where its warm and not wet lol
I cant remember where I started to use mate ( my dad was a cockney so learnt all the slang when I was young) so I am from the wet and windy UK
This is why I am on here so much as its to wet to fly or to windy or both or cold wet windy ( right stop now)
