Features -With the new LamaV4 you get a completely assembled and ready to fly micro heli with a coaxial counter-rotating head design that is so stable almost any first-time flyer can be hovering like a pro in no time. The LamaV4 offers things other similarly designed micro helis can’t – the power and precision of ESKY 8g servos, an advanced 4-in-1 controller, and a great looking, lightweight body that really stands out. The LamaV4 features counter-rotating main blades that cancel out the rotational torque that makes hovering a challenge in conventional helis.They also make rudder turns much easier by slowing down one or the other blade without affecting the stability of the aircraft. This is truly a helicopter that most anyone can fly and beyond your dream. -Coaxial, counter-rotating blade rotor design provides incredible stability and positive control. -Full RC system set Included, ready to flight out of box. -Pre-installed ESKY 8g servos and 4-in-1 control unit -No installation or assembly required. -Dual 180 motors makes the LamaV4 powerful and efficient. -800mAh 2-cell Li-Po battery pack is low weight, high power and provides flight durations of 10-15 minutes per charge.
