<BODY lang=EN-US vLink=purple link=blue bgColor=#ffffff>
<DIV><FONT face=Arial>I have found a HUGE amount of quality variance in the ali.
arms that are out there. The casting and anodizing can be very "poor". Some arms
that are listed as JR will simply not fit a metal JR output shaft. These
same arms would not fit my airtronics servo either.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial>What you need to look for is </FONT></DIV>
<DIV dir=ltr><FONT face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial>1. If the arm is rotationally a loose fit.
Rather obvious, but the output shaft screw can make you think that it is OK.
Even if </FONT><FONT face=Arial>tightened down it can actually rotate a
degree and change your trim settings during flight operation.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial>2. Look closely to see if the arm goes
all of the way down on the shaft. I have found a gap between the top of the
output shaft and the servo arm. One arm looked good but could be rocked even
when the screw seemed tight. </FONT></DIV>
<DIV dir=ltr><FONT face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial>3. The hole for the servo arm screw is often too
tight. The screw sort of self taps on the way in. You think it is all the way
down but it is not. Later on the arm becomes loose and thing get ugly. In this
case the hole be drilled out with no problems.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial>The ali. arms are attractive but lately I have
been going over to the discs, for strength, or the newer and thicker arms.
Please just "junk" any arm that does not look or feel right.</FONT></DIV>
