aileron servo gears FOUR times. At first I thought it was infant mortality
followed by the dumb ass missed a piece of crud in the servo case. I don’t
think that’s what happened<o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Here’s the setup. The plane is
an Aries, JR 8231 servos. Plane and servos are less than four months old:
about 60-70 flights. Right aileron has broken 3 times and the left has
broken once (one each today). The breakage has always been slightly right of
center on the output gear. There is no static binding. The hinge lines are
sealed. I can’t be positive but I believe the gears are breaking
during a down line snap. BTW, I snap to the right. I don’t believe its
flutter because the breakage is NOT at center. I don’t believe its excessive
travel because the breakage is not at the extremes of
travel.<o:p></o:p></SPAN></FONT></P>

place enough load on an 88 oz. servo to break a gear? I have used this exact
same servo setup in two other planes. I did break a gear one in one of those
planes. Again, I just chalked it up to wear.<o:p></o:p></SPAN></FONT></P>
