RTF is not quite true of that package. It does not include the flight batteries or charger.
It requires either 2x 7.2v NiMh @ 3,000+ mah or 2x 2S lipos @ 3,000+ mah.
At least $50 additional cost for NiMH or as much as $250 for lipo+ charger.
Since a beginner can purchase the NiMH's and charger to start out with, then move up later, the combo price is still very good all things considered.
You can even move up one cell on the NiMH batteries to get better performance.
I hope that this package snares people who otherwise would not get past the 3CH planes.
