iy's a hitec eclipse 7 with 4 hitec servo n a futaba digital servo for the rudder!the antenna seems to be okay!do u think it's the crystal?coz i had no similar problems before,i just started to hav them when i finished taping the receiver,attaching the wires n putting the rubber foam!i had attached my battery indicator on the foam which was right on the crystal but then i removed the indicator n the foam n i got the prob once more!am still puzzled for that!i also saw that i had plugged the battery wire upside down by mistake!(the yellow wire being down) do u think it was this which caused all this?
