No,the first reciever channel 3 stopped working.The other reciever would range check fine until the engine was running,then at a distance,servos went crazy.The third reciever range checked fine with the engine running,we taxied around a few times no trouble,i flew the plane at about half throttle for atleast five minutes with no problems,as soon as i cranked up the throttle,the plane started getting hit!luckily she was landed incident free.The plane is new and has never been any accident,two of the three recievers were brand new.
