Received on Saturday after a first order with helicopter having a defect (a rod supports twisted back ...). Then after 4 days of indoor use, few collisions and a few falls (including infrared reception problems), there was a short circuit: even on the propellers turned off despite leds off and smoke on the PCB. I was forced to cut off the cockpit of a son of the battery to stop .... Otherwise flying very well and fun and inexpensive except for 4 days of use .... Nondurable
