The "plastic only" parts don't include the bearings, bushings, bolts, or other little metal bits.
It's a great feature that they sell them that way.
The Align 60A seems to be turning out to be a solid performer, no problems, no burst-into-flames, but not as hot as a Jazz. Jive has fit issues, they both have $$$$ issues.
No upgrades needed, but I would advise popping for the yellow paddles, at least, and also maybe tail blades and landing gear. The heli is flat black; pretty difficult to see apart from the canopy.
