glitches (was Lost Abbra)</DIV>
<DIV><BR></DIV>
<DIV><FONT size=2>I'm currently chasing a RX problem which nearly cost me the
plane.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Many flights with no radio problems. (had a couple of
instances of covering comming lose on the ARF....)</FONT></DIV>
<DIV><FONT size=2>Goofe up and caused a servo to over-travel stripping a gear,
so I replaced the servo. 3 flights after that with no radio
issues. Then I stuck in an RX volt-watch device. 2 more flights no
problems.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Got to flying it around the last time it was in the air and
the plane started glitching, so I landed. When the plane stopped at the
end of the runway (less than 75% of my normal antenna down range check
distance) controls went absolutely nuts, including throttle. (which is really
strange because its an electric model)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>When the glitching occurs, it pulls the volt-watch meter
down to the lowest indicating light.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The plene:</FONT></DIV>
<DIV><FONT size=2>Quest 3D G2</FONT></DIV>
<DIV><FONT size=2>AXi 4120/18 using Jeti 70 amp ESC</FONT></DIV>
<DIV><FONT size=2>Hitech Supreme 8 RX</FONT></DIV>
<DIV><FONT size=2>4 Blue Bird 621 servos (90 in oz)</FONT></DIV>
<DIV><FONT size=2>2700 mah 4-cell NiCd RX battery (ESC has no BEC
function)</FONT></DIV>
<DIV><FONT size=2>2 X 3s 3600 mah LiPo for 6s power (appx 11 to 12 min of
Sportsman level Pattern per charge)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Polks Tracker-III TX</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I've swapped out every servo (I have 4 spares)</FONT></DIV>
<DIV><FONT size=2>I swapped to a Futaba 127 DF RX and to a Polks Seeker-II and
a Seeker 6</FONT></DIV>
<DIV><FONT size=2>Changed the switch harness to an MPI heavy duty with volt
indicator.</FONT></DIV>
<DIV><FONT size=2>Changed to a 900 mah 4-cell NiCd for the RX</FONT></DIV>
<DIV><FONT size=2>Tested with and without the volt-watch</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Only had one good range check since the problems started
with an RX anywhere near the airplane, that was with just the motor and the
rudder servo plugged in. (original RX)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Wierd part... the whole radio system works fine if I pull it
out of the plane and lay it on the ground similar to how its laid out in the
plane., including the long servo extensions for ailerons and elevator an
the motor system. (put it back and the glitching is back) This is
repeatable with any combination of the servos I have.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The other RX's tested all work in the planes they are
normally used for.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>TX operates all other planes I have with no issues. (I only
use 2 frequencies even though I have a few synth RX's and the TX is
synthesized)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Current antenna down range check is 50% of my norm, so I
don't dare fly it. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I've been thinking of putting together "glitch busters" ( <A
href="">http://www.uoguelph.ca/~antoon/gadgets/gadgets.htm</A> ) for use
on the long lead channels, but can't see why I should need them if the system
worked for appx 3 months without them. I have had a plane with
exgensions that added up to right at 1 meter where the devoces cured
problems , but those existed from first time the radio was plugged
together.</FONT></DIV>
