Tigerdude,
Yes, you want to turn your radio on first and then your receiver. Turning off it exactly the opposite, receiver off first and then the radio off.
As far as your servos. First thing. Disconnect all of the control rods from all of the servos and turn your radio on again. Is the buzzing still there??
Yes, then there could be something wrong with the radio and may need to be checked out. Unplug all the servos and plug them back in one at a time until you find the one that is buzzing. It's possible that you have a bad servo.
No, then the problem is with the linkages/control rods/control surfaces. One at a time reconnect the control rods back to the servos and note when the buzzing starts again. That will tell you where the problem is and you can start to see if there is binding, tightness, or other problems with that control surface.
Try these out and let us know what you find out. If you can at least narrow it down some then we can start trying to figure out how to correct the problem you have.
Hope this helps
Ken
As far as your servos. First thing. Disconnect all of the control rods from all of the servos and turn your radio on again. Is the buzzing still there?? . . . No Ken, the servos by themselves work fine and never any buzzing without the connections (pushrods, etc.) attached. I disconnect all the pushrods so that its just the bare servos and they work great.
Yes, then there could be something wrong with the radio and may need to be checked out. Unplug all the servos and plug them back in one at a time until you find the one that is buzzing. It's possible that you have a bad servo. . . . The radio works great and as stated above, all works good without pushrods.

servo linkages and pushrods for the rudder and elevator all seem to be gliding smoothly without any binding or tightness. I don't believe the nosegear is binding or catching in any way so I don't think it is that. As far as the throttle, that is apparently where most of the buzzing is coming from, especially when it is full open or closed, but again can't be sure. The problem occured BEFORE the control surfaces were connected (just the servos connected). I WILL CERTAINLY DO AS SUGGESTED HERE ABOUT RECONNECTING ONE AT A TIME, AND I WILL GET BACK TO YOU ASAP.
Could it possibly just be the endpoints as suggested by Gravityisnotmyfriend? My computer radio does have the endpoint adjustments but without the booklet can't know how to do it?
By-the-way, my radio is a Futaba T4EXA. I found the booklet on the net but my internet is so slow it takes forever to open the link. I will keep trying and when I get the whole booklet displayed I will print out all the pages.
