Yes...a 450 is a good size to start with...Iwould'nt go with anything smaller though. I would make some training gear for it as it will help a lot with landings and take offs......the first few times you fly it will help you to not tip the heli over. The mSR for me was just a way to fly indoors and practice all the different orientations and get that "muscle memory" in my thumbs so things will come more naturally when Ifly the much harder collective pitch heli. Take small steps and don't try to do to much....practice on the SIM(especially the hover training)....and you will be on your way!!
