<DIV><FONT face=Arial size=2>Your observations are correct. As the feedback pot
wiper moves with the output, the servo will maintain position (try to)
regardless of slop. Wiggle the surface through the slop range with the radio on
and you'll feel the servo work to hold position, the digitals are very
successful at this. However, this extra movement quickly wears the pot element
and accuracy will soon diminish. Additionally, the servo motor is getting it's
tail worked off reversing back and forth to keep position - I'm amazed that we
don't suffer motor failures. Finally, this extra work takes power - so more
energy is removed from the battery per flight the more play there is. Tight is
good!</FONT></DIV>

<P>Bob,</P>
<P>Yes, I have seen and felt the slop on ground. However, with this type of
digital servos I can NOT feel any difference when fly. My point
is: If I can not feel any difference why we need to change the
gears? Probably the reason is that are digital servos and the servo can
compensate so fast to the slop that normal human "precision" can not feel any
change. It will be interesting to get the JR engineers opinion in this
regard or the JR Team pilots.</P>

<DIV><FONT face=Arial size=2>Vicente, the metal gear servos develop slop in
the gear train almost immediately, worsens through the first 50 flights, and
stays SLOPPY. That's why most of us change the metal gears to the nylon, and
the same reason JR offers the 8411 and 9411 WITH "nylon gears", as the SA
versions.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT></DIV>
<DIV><FONT face=Arial size=2>ON every 8411 I've changed, I have immediately
noticed the slop GONE. It is worth it.</FONT></DIV>

<P>I have a question in regard the conversion from metal to nylon gears. I
have two planes one is older. Both with 8411 and 9411 metal gears. When I
flew the new one with new servos I could not feel any difference in the
air compared with the old plane. The new plane didn't not have any
noticiable slop. Now both have develop some slop and looks like the slop
does not change with time. I can feel the slop with my hands but I can not
feel it in the air. Both planes are flying great. Are you guys having the
same experience? if yes, why we need to replace the gears?</P>
<P>Please don't tell me that I am too old to feel the difference. I know
that the first problem you notice is that trim changes continuosly.
Unfortunetely, this could be true since I am more than 50 forever. </P>

<BR>> This is leaving the metal output gear in place. I choose to do
this on all <BR>> my servos I convert. I like the Metal Output gear
as it gives better <BR>> connection to the aluminum Servo Arms I use.
I know some have chosen to <BR>> replace the output with a plastic
one, either way works...But the 8411SA <BR>> Conversion kit doesn't
include the output gear just the internal gears <BR>> needed and a
new face plate. <BR>> <BR>> The gears are actually from an 8101,
8231 gear set This is where you get the <BR>> nylon output gear if
you choose it.....Like I said I don't, the nylon output <BR>> gears
have more flex than the metal ones and I prefer to use a machine screw
<BR>> with blue thread locker as opposed to the self tapping screw.
