I googled it and I stand corrected. I've never heard of CL56 but know the RJ as a CL65.

The rest of my post I stand behind. The fact that you had more time prior to RAA is a good thing and it's great to hear that. I'd be careful of talking about flying cargo around with no more than a PPL. The FAA interpretation on PPL privileges is pretty strict. Perhaps the FAA regs don't apply in the "Carribean".

Are you saying people DON'T go from zero time to CL56 (or 65) type ratings in four months. After re-reading your post I see you had your PPL when you started. After going to RAA's website, they say 14 months from zero time to regional pilot which includes working for 4 months as a CFI. Working as a CFI is a good thing.
