I setup everything on the PC and everything seems fine. Transmitter seems to be working fine. Disconnect PC and plug in flight pack will not arm. I have even set it to always arm. I am using a cc3d atom, spectrum SPM4648 satellite receiver, and DX6i transmitter. I am at my wits end. Looked on the web and cannot find out why it won't work.

Ok I got it to arm. I had to manually set the transmitter up seems on channel wouldn't assign. When it spools up now there is no slow spool up it that normal? Do I need to adjust the throttle curve right now it is straight?

Multicopters do not spool up slowly like regular helis.  The motors must react very fast under all conditions.
