NDBs aren't that bad especially since they have RMIs in the cockpits. Arcs are a piece of cake with RMIs as well. All you do is follow the needle and match the heading. However I can see that if you have no sense of awareness and poor instrument skills and some cross winds you're probably not going to do well. Still not bad at all, all it takes is one good day of continuous approaches on flight sim with an airplane that has an RMI. If you need help, you might want to find a senior instructor at your local airport and do an hour or so of sim with them. By the way I can't belive it's almost 2009 and we're still talking about NDBs.
