CC3D memory is small and completely full and thus CC3D does not get any new features.
CC3D does not do GPS flight modes and does not have built in RF telemetry.
CC3D does work OK for FPV and LOS.
If you can afford it, a Revo class FC has more features that you might want to enable later.
The 'next' version of LibrePilot will have support for some FCs that fit between CC3D and Revo in power and features. This version is being developed, but can be downloaded and used even today.
