not a good product, it flew but the helicopter kept rotating with the blades as well, full trim also could not compensate it, there was some manufacturing defect. i however had bought a better quality one for 1400 on flipkart - model art, that was a much better choice, worked well.
i tell every one to use re-chargable battery for remote. you should set the trim of the helicopter before flying you should see many videos of rc heli read more
It is very bad product.After 1st time flying,the toy is not working though Batteries are in new conditions.
