Just bought this 4 channel heli. Like this heli cos the main and tail motor are both brushless. Brushless motor will last very long. It has altitiude hold but don't really like the drone type Transmitter where the throttle stick is at the middle. It did not give full control over the throttle and altitude. 2nd speed is much better and more responsive from the transmitter. Overall it flies well and bought this heli mostly is to add to my collection of fuselage heli. Thanks for watching and questions are welcome.
