For a second I thought all the plans I had in my head went to dust lol I was wondering if I was losing my mind lol
My first custom build and need advice and pointers...

Heheheheh, sorry if i'm confusing you, try to google wiring diagram for quadcopter, maybe it wil shed some light

Can I ask you both something... If i was to make my centre plate more rectangular rather than just square would that affect the centre of gravity? as will it fly out of control if the base is more rectanglar? Im still keep the arms at 45 degree intervals but they will be spread further apart and not in a square shape

In my opinion, it would be alright, jakson has show some example at the previous page, the quad with the wooden arm, it doesn't use symetrical arm between the 2 front motor and the 2 rear motor. As long as the left side motor is a mirror image of the right side

Thankyou, I just wanted to change the design or my plates a bit to make it my own if you know what I mean, want to go for a stealthy jet type front and slight more rectangular so I can place my battery at the back 
It'll be fine as long as the motors are placed square from each other. You can make the whole thing rectangular if you wanted, just have to split pitch and roll Pi settings.

Am I making this more complicated for myself? Lol
I'll leave that for you to decide.

So far this my design, what do you guys think?

Be careful with the holes in the arms, in my experience, the holes is a bit too long, it compromise the stiffnes of the arms , i think it better with short holes but with 3 or 4 pairs per arm

I haven't yet decided how I will strengthen my arms up but I agree with the fact that I have dramatically reduced the overall strength of the arms with the slots so I will look at reducing the size. As for handling crashes... What makes you think I will crash it lol I will strengthen the design but am also trying to reduce weight in any area possible. Still have a lot to do to the final design

If you never flight a quad before, i'm sure you will have a crash lol
Better prepare some extra props, my quad already crash twice, and broken 4 sets of carbon props. Till i get the feel of the controls, gonna use plastic props instead. Already making a third design frame hahaha, going with a H frame design with asymetrical front and rear arms (front arms is shorter than the rear arms)

That's where the Mixer Editor in KK2 works well, It can also be be done with the Naze32. With CC3D they offer a few options, but it would be nice if they explained or pictured the geometry of the choices. Many 250 racing quads for instance, aren't really square , but more rectangular, wider side to side.
With asymetrical booms you run into the problem of Center of Gravity vs. Center of Thrust. They don't line up.
This guy has a number of vids on fine tuning the FCB.
I like how he copies frames in ply from pictures off the net. No fancy tools or CAD programs.
He cheated a bit on the COG.
He did need to add a few holes with hole saw though to lighten the plates a bit.
It's cool the way the KK2 ends up with the proper geometry showing in the LCD, a great confirmation that everything went right.
For someone who doesn't have exotic tools a decent looking multirotor can be had.
Note it's one of many that he has built, I just added some imaginary 'holes' to the plate.

Looks nice, what is the material and paint?
I find wood to be one of the best building materials, looks like one would need a miter box, but not much else. Most people have more tools to work wood than anything else.

Updated drawings/plans... what do you guys think?

One question, is the arm a tube or a square? If the arm is a tube, be careful with aligning the motors, just make sure they all have the same angle of thrust, that was my mistake on my first design, i didn't calculate the vibration of the motors, it makes the motor mount to turn and make the thrust angle different on each arm
