The Blade mCX is the perfect heli to start with. It's small enough that a corner of your living room will be plenty of space to practice in, but still has all the same features and identical controls to all the larger helis.
Bind-n-Fly (BNF) versions of the helis above are for those who already own a Spektrum transmitter and do not need to buy another one. They are identical to the Ready-to-Fly (RTF) versions above, except that no transmitter is included.
