[NSRCA-discussion] Interference Problem

[John Ferrell]

Unless you consider the Focus expendable I would swap out ALL of the servo's at once. They don't have to be competitive, just safe. If there are no further failures, add the pricey servos back one at a time. That way you will only have to experience the fault one more time. If it fails with the replacement servos you need to try another transmitter. 

I am assuming you have made sure there is no metal-to-metal vibration in the plane and all servo extensions have been replaced.

  Hopefully someone can help with this. I have been getting interference on my Focus for the past three flights causing me to land, and I can't seem to solve the problem. Initially I thought it was the RX and TX, so I changed them both and moved to an entirely different frequency. I flew the plane again and it glitched in the air just as the first two times. The glitch is a quick and significant change in attitude. When I landed, the regulator was warm so I removed it thinking it was going bad. I replaced it with a regular 4 cell NiCd pack. I changed the receiver once again and am still getting the glitch. I decided to remove all the arms from my servos (JR Digitals) so that there would be no load and see how the problem is. The servos, under no load, buzz considerably. It's not the "I'm under load" type buzz, but more of a twitching, crackling type buzz. Are my servos going bad? When I plugged in a new 8417, the buzz is non existant in that servo. 

  Any help would be appreciated!!
