[NSRCA-discussion] Interference Problem

[Jay Marshall]

What kind of servos? I have some 9xxx Futabas which also buzz all of the
time. The only thing that stops them is to completely disconnect the control
linkages.

I'd be quick to say that was the problem, but there's still the odd buzz in
each of the servos under no load.

Reminds me of a problem I once had with servos. Had one that was PARTIALLY
bad. If you did a normal control check all was well. However, it you moved
the servos slowly to max they would go ape at some point and short the
battery and therefore taking out ALL of the servos and receiver.

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!!

Scott
