You're only learning to drive the wrong way around, it ain't that hard! The right way is motorcycle to car, you are just planning to do it backwards. OK, a wee bit harder than the first time, as far as controlling the machine is concerned, but you already have the nav, airmanship, instrument and operations side of things, they are no different. You have the nous. All you have to do now is learn to actually fly a helo, which is great fun, and forget all this rot about learning to hover - it may not seem natural at first but anyone can do it, (neither is gliding, is it) learn the P of F and get to grips with a machine you've always wanted to fly, but your Cessna never delivered...
Of course, a lot depends on you, your age, your attitude, continuity, all sorts of variables. You have control of most of that...
Go on, get on with it, and post back here about how much you love it, won't you?
