Man I have got no idea what that could be on an electric... if it was a glow plane I could tell ya... I've heard pretty good things about these planes.. maybe you should send it back to horizon hobby ( i think thats who makes them?) call them or email them and Im sure they will replace it for free with a new one.. u may have just gotten a bad airplane, if you just hold the airplane and throttle all the way up does it die then too.. even with out rollling or attempting take off? it may be a Transmitter/Receiver problem as when it just gets far enough away from you it dies out... so try to just throttle up while your holding the airplane and see what happens
