RE: Blade CX-2
Tinchao,
No, The materials are the same and both fly the same but out of the box the CX2 is setup to fly alittle more stable and easier due to the setup of the servo horns.#4 and the other on #5 holes. Thats all. The new radio is alittle nicer as you can fly with other buddies and never worrie about the channel as the CX2 uses spectrum technology versus CX is on 72mhz like the typical plane and heli models use. The spectrum technology is the way to go and the transmitter only uses 4 "AA" batteries versus 8 in the old CX. I know its 20 dollars difference but its worth it in the technology aspect of the radio. Besides ....That 20 dollars will not go very far the first time someone turns on a radio near by that is on the same channel and crashes your bird and hits a car to do alot more than 20 dollars damage.
