The
Syma S107G is a great first helicopter. Only 3 channel, so not too much going on, and coaxial with gyro, so it's very easy to fly. It's what I bought my 8 YO nephew for christmas, and he loves it.
If you're really wanting an e-flite (blade), I would probably go with the
Blade Scout. It's 3ch again, never flown one myself, but should be pretty easy to fly. I have 3 other blade helis, and they are pretty tough.
Other choices would include the Blade
mCX or
mCX2.
I've flown a variant of the mCX (the tandem rescue) and it's very stable.
You'll want to go RTF, since these small helis have all-in-one Rx/ESC/Gyro/servo units. You're old radio system is probably not compatible. (Unless it's spektrum DSM.
