Query: Poor quality

The tail rotor fell off right out of the box on the first throttle up. The landing gear fall off if you do not glue them yourself. Not only is it poorly made for the money but it is an extreemly touchy machine. Main rotor to tail mixing have to be perfect. Final thought.... After several hours of hard work adjusting the tail to main rotor mix I managed to get it to stay in the air for a few seconds. If you want an R/C helicopter try the Japanese made Hirobo XRB SR.
