Troy and Jim,</FONT></SPAN></DIV>
<DIV><SPAN class=000270622-10022004><FONT face=Arial color=#0000ff size=2>Now,
the biggest source of pot wear will be the drive to the field/contest. Every
bump in the thousand mile journey to the NATs will jiggle the control surfaces,
and dig holes in the pot wipers. We need to put "gustlocks" on our surfaces,
preferrably far from neutral.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Troy,</FONT></DIV>
<DIV><FONT face=Arial size=2>Tell us more about the contest and the
electric. I assume you didn't fly on Saturday because of the wind.
It was blowing so hard at my place Sunday morning that I didn't even check
Lancaster until 10 and then found out it was calm out there. Sounds like
I missed some fun.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> Re: What's a JR 9411SA
servo?</DIV>
<DIV><BR></DIV>
<DIV>
<DIV><FONT face=Arial size=2>The 9411 is a mid sized servo. So it fits in
the stab just like it would in a wing. I didn't look closely at Tony's
setup. I know he is not using a matchbox. There is no need. Matchboxes are
for using multiple servos on each surface. Basically all a matchbox does is
act a "Y" harness that has subtrim, reversing, and end point adjustments in
it.</FONT></DIV>
<DIV><FONT face=Arial size=2>If you plug the two elevator servos into the RX
in different channels you already have these features. Especially in the 10X
as the dual elevator function is the simple flip of a software
switch....then subtrim the servos independently, and reversing as
needed...then set the end points and they are done.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Where the matchbox shines.....is when you are
running (4) servos per aileron.....Your RX only has 10 channels in it. So
are you going to use 8 channels just to mix your ailerons together?
NOPE...So the question comes which servos get Y harnessed to each other and
do you use (2) RX's and so on. The matchbox allows you to hook the entire
wing panel to a matchbox and set each servo up independently for center,
rev, Travel....then the match box just plug into one channel on the RX. Do
the same thing for the left wing and now your setup is not much more than a
normal pattern setup with only 2 ailerons servos as far as the TX is
concerned.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The Matchbox also has a neat feature where can
power the servos on it separately from the RX power source...So you could
put a switch and battery pack on the left wing, right wing, rudder, and
elevator on a big model like Quique's Yak 54 or the big H9 Ultimate
Bipe.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The idea behind a matchbox is to make the
complex model easy to setup....it allows matching of servos that are
connected to the same channel in the RX. If you have a radio with dual
elevator capability there is no reason for a matchbox in this
application.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have seen H9 Funtana's with matchboxes on the
elevators....and I have seen 25% extra's with dual RX's......Our pattern
models are pretty simple in their layout. Even if using dual elevators....we
are already using dual aileron servos and our radios are already setup to do
it....both major radio manufacturers 9-10channel systems, the 8 channels,
and I think even some of the 6 channel systems are now capable of the dual
elevator setup and have been that way for years now.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't think it is better than the CF rod
setup I have been using....but if setup properly I think function is just as
good. As Tony has said the dual elevator servos are a pain in the behind as
the servo pots wear. The endpoints change the centers change. In talking
with Tony when he was flying Ty 2+2's with the dual elev setup he was
changing servos every 30 flights because the pots were starting to show
wear. If this is the case the then the setup time and pain in the
behind of dual servos gets old quick. A single servo is easier to change and
setup because there is no matching.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Tony's theory is the Electric is going to much
less servo wear...so the dual servos is no big deal. He isn't going to be
changing the servos for 10,000 flights.....LOL...actually I'm joking but the
electric has to be better on the servo pots. We'll see what happens. Also
the newer digital servos that we have today are way better on pot wear and
centering than the servos Tony was using back in the dark ages of
97'</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I know Quique uses dual elevator servos also.
The Smaragd and Partner will tend to have a forward CG if you use a
single servo up front and build them stock. So Tony just built the model as
close to the design intent for everything but the power system. It is a very
impressive model. I enjoyed flying it. Only got 2 flights on it but one was
a contest round of P-05.</FONT></DIV>
