<p class="MsoNormal" style="MARGIN: 0in 0in 10pt"><font face="Calibri" size="3">I checked a few of your suggestions.
Yes, it happens when the radio is very close to the plane and yes only when it’s fully charged. I moved the radio a few feet and it does not happen or does it for a very short time. This is a good thing to know, that it will not happen when the plane is flying. I also disconnected all the servos as someone suggested and reconnected that servo to a different slot and it did it again when the radio is very close to the plane. So, it seems that the servo is OK.</font></p><p class="MsoNormal" style="MARGIN: 0in 0in 10pt"><font face="Calibri" size="3">Maybe that’s the way it is, now the question is: why is it just the rudder servo? Thanks again for your help.</font></p>
