Is there a way you can fly off these in FS? Lately, in FS9, i've been flying the amazing Carenado Mentor VOR-VOR (looking on FS's map trying to find places to go). I was wondering if you can fly off NDB's also?

yup

Sure you can,only be advised that the range of NDB's is much less than of VOR's.Depending on the type of NDB (terminal area / enroute), they have a range of appr. 25/50nm.

Here's a very handy site from which you can learn to navigate by dead reckoning, VOR's, and NDB's - including NDB and VOR approaches:http://www.navfltsm.addr.com/I highly recommend going through the whole tutorial (even the parts you already understand) because it's good practice and helps you tie things together very nicely with well-described flight plans that are very satisfying to complete as the story progresses (career mode?).Hope this helps,Kevin

most do, but there are long range ndbs as well.In my experience the ranges of ndbs in FS are too low compared with the real world. Could be because FS has only a few categories (like VORs) and the real ranges don't match.Of course the age of 250nm NDBs for navigating long range flights from Europe to South Africa and India are over.

Actually the range is greater. FS takes the average range values for each power setting mentioned in the US AIM (section 1-1-8-e) and multiplies them by about 1.5. You can find the power of an NDB using the FS map dialog.
