Four years ago I was in the same spot as you. 15yrs giant scale aerobats, 3d, etc. My first foray into jets was the PST Panther and as Fender says; the hardest thing to adapt to is the landing. Expect to knock the gear off your nice scale jet. I did, about half dozen times before you "figure" it out. That's the disadvantage to starting with a nice scale jet- you will very likely damage it.

Starting with a Boomer or the like gives you a chance to get familiar with not only the turbine but, the stuff that we're not used to with an aerobat. like the damn retracts. You'll get familiar with the landing approach and bringing it down without knocking the gear off it. And if you do, it will be an easier fix and you won't care so much that you dinged your "ugly" boomer as opposed to your scale masterpiece. Yes, you will get bored of the plane very fast, probably within 3 months but, it will have given you those skills that you need. Just my thoughts on it.
