Well Crashem, I certainly don't believe that makes me a pro. However I do have quite a bit of flight experience and THINK that, just maybe, that might help me understand how to take off, turn, fly straight and level, control power, fly an approach, set up for landing and avoid/recover from stalls with ANY model.

How about setting that whole point aside and answering this - do you think it is justfied to buy a little more plane, but plan to fly it tamely for awhile (via short throws and slow rates) rather than tippy-toeing through one model after another? If not, why then?
