<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>
