This is a very nice trex 450 heli with micro beast.Just add battery and transmitter and you are flying! Heli is super clean and flys great. Only for skilled pilots! The canopy has some tiny cracks around the head from taking it on and off but they are barely noticeable. All align servos on the head and jr ds3400g high speed servo on the tail.Carbon fiber main blades. Fast and free shipping! Check out my feedback!
