Welcome to the addiction... errrr hobby Sean!
I started out on a Slightly larger coax heli and I was hooked. You are lucky to have the very best first requirement of a successful RC Heli hobby, some say a sim is most important... starting out with a good hobby grade heli (as the mcx most definitely is)... but having a girlfriend (or wife) who enjoys the hobby as well, or at least enjoys the fact that you derive fun out of it is absolutely a great start!
There is an entire forum here dedicated to coaxial helis like the Mcx here on RCGroups
. You will find this is a very friendly and helpful place!
