RE: cx2 case
This is what I did and I am very happy with it. A couple of foam blocks hold the heli in place, one more for the Xmitter. It is deep enough that I can use the top tray for parts, and between that and the two lid compartments, it holds everything I need in one box. The bottom even has room for extra bodies. It is a Stanley 24" Series 2000 box. I got it at either Lowes or Home Depot.
