I have a 3 ch heli. Flew it 3,4 times. The rotor blades and balancing rod are damaged. The whole thing with tx ,rx , cover, charger will be provided. Expected price just 1700  . +courier charge extra. Good for beginners..
Here are the pics

Is there any servo in it?
Is it 2.4GHz?
What is size of main rotor?

No there are no servos in it. Its just a beginner's helicopter. There are two main motors in it of size 131*2. Its just 27.145mhz.
