He's pretty cool....
But we can't talk about him too much on here...He gets the list emails
too! Or lets put it this way. Margo gets the emails and then saves them
for him to read.
The best part of all...was the wedding.
Thursday in Vegas, We are getting married at 7pm. Jerry and I are at the
flying field practicing for the weekend contest. Margo and Jenny are
getting the hair done, dressed, and all that girly stuff. At about 4pm
Jerry and I look at each other and say well I think we got time for
another flight. Get done throw the models in the car. Then we drive all
over creation looking for a car wash, because the entrance to the field
was just play a mud hole. Find the car wash...I walk into the Hotel room
at 6pm, the limo is picking us up at 6:15pm...Shower and dressed,
hooking up the bow tie at about 6:14pm and the phone rings...the Limo is
here to take you to the Church.
Nothing like perfect timing.
I think Jerry got the same rear end chewin' that I got..but we made it
on time.
Like I said its great to have a pattern flyer in the family. It always
good to have somebody to bounce ideas off regarding pattern and models.

Troy:
Thank you very much for taking the time to walk me through this! I will
set this up today and try it out.
Chris
PS- I got to meet and spend some time with your Father in law last
weekend at the Winston Salem contest. How many of us are lucky enough
to have a Father in law that flies pattern???? Awesome

Chris,
Ok this is the way to solve that...VTR is a Lin-Lin function as
you stated.
Instead turn on your normal expo like you want it on your low
rate like you want it.
Next go to program mixing on Pmix 6, 7 or 8 these are the mixes
that are available for curve mixing. We are going to create a curve mix
that activates at about 90% stick travel to mix rudd to rudd. This way
we can create any kind of expo curve we want. Its a custom one. It will
be dependant on what ever curves you already have setup...so lets use
the radios expo function for the center part and create a new curve at
the ends...by adding more travel via a mix...when can do this on a curve
that we select the points on.
At Program Mix 6-7-8
The screen will say INH
Press 4 and 4
This will bring up Rudd->Rudd
The next thing on the screen will pop up as type "Norm" press
select to get it to read "CURV"
Next press enter.
This will bring up a mixing screen that shows only one point on
the curve in the middle. Also on that screen will say EXP "OFF" Press
sel to turn the expo function for the curve mixing "on". This will make
a smooth transition between points. The horizontal line will be at zero
value. This zero value means use the current expo values and slopes.
You are mixing rudder to rudder so any time there is a zero
value there is no change to the current rudder and expo curve. Ignore
the mix values for now and press page. It will bring up your switch
selection screen. You can pick like FM2 to have the mix on or off. or
the gear switch or something like that. You can even set it up to only
work when the engine is below a certain throttle setting. Lots of ways
to activate this mix....we will talk about why you might need those
options a little later. For now pick a switch. Press the "SEL" under the
switch of choice and it will toggle to POS1 of the mix.
Press page again...under MASTER it will say "NORM" we want it to
say "ORIG". This means that the curve will be dependant on the rudder
stick only and not anything to do with rudder rates. Its like what I
described to Ed. Leave the trim function "OFF" If you leave it as normal
then you will have to reach the rudder rate value before the curve kicks
in...So if your low rate never gets to the 90% travel of the servo the
mix will never kick in...so setting at ORIG will make it totally
dependant on the rudder stick position and not the rudders servo
position.
Press page again and it will take you back to the mixing value
screen. Pretty easy you are now all setup to put the mix values in and
setup a curve.
Flip your switch you chose until just under #RUDD is says "POS1"
Then follow these steps below to setup a curve.
Move the rudder stick to one side left or right. The closest
point you can make is about 88% and about 12% on the other side. Hold
the rudder stick over to the 87-88% point and press store. This will
give you a point on the curve at the 88% value. Do the same thing at the
12%-13% value. Now your curve will have 3 points. marked 1-2-3. Between
points 1 and point 3 don't make any changes leave that at zero mix. This
way your rudder expo and so on stays the same..in the middle where you
fly.
Move the rudder stick to the stops left and increase the mix
value to say +30%....this will take your normal rudder rate at full
deflection (in your case low rate) and increase it by 30%. This will put
you to high rate when you hit the last 10% of the stick travel. Since
you picked to have the exp function for curve mixing turned on the
transition from your normal expo to the higher rate will be smooth and
ramp up rather than go straight line to the 30% value.
Your value maybe 10% or 20% higher rather than 30% higher. Or it
could be even more like 40-50% higher. Watch your model and see what is
going on so you don't over drive your servo.
Also of note...any rate you set in the D/R screen will get the
extra 30% added to it at the end when this mix is ON...So this is fine
if you are on low rate at 70%...but when the stick hits full deflection
it will jump up to 100% travel. The problem is this....If you high rate
is already at 100% it will get another 30% added to it.....it will go to
130% and might over drive the servo
There is a solution to this below but make sure you are not over
traveling your servos until we are done setting it up.
DO the same for the other side too. Now the last 10% of the
stick travel sends you via a curve mix to a new rudder D/R
With flight modes this is easy. You can have it active in one
flight mode and not another....Since flight modes can have independent
rates...you can have your high rate with this mix turned off or you can
adjust the value of your high rate back and leave the mix on and make
sure its not over driving the linkage.
Notice the POS 0 or POS 1 values you can create two of these
little curves. One could be zero mix everywhere or one could be a
smaller amount of mix and the other a higher number.
Always keep the middle values on the curve at zero. And always
make sure to not over drive the servos.
You now have a rudd to rudder mix setup to give you normal expo
in the middle and steeper curve that you set the endpoint on at the end.
Always realize you are adding that 30% or what ever your number is to
the already programmed D/R.....In this way you can create custom expo
curves and inflections points where you want them.
By the way the 10X has 3 curve type mixes each with 2 different
mixing curves. SO you can do this same thing to all 3 primary flight
controls. When you have dual elevator servos on and do it to elevator
they will work together, when flapperon is on for ailerons they will
still work together.
next thing is doing funny stuff with turn this on and off. My
guess is you want it for stall turns. So set it up on the Thro stick as
the switch and program the point on the throttle stick where is swaps
from position 0 and Position 1 in the mix. Then you can also have it on
a FM to turn it off so that when you are trying to do your 45 down
snaps...the mix is off and you are not getting this maxed out rudder
throw.
Really it took me about 2 mins to setup and 10mins to write it
step by step. Its super easy...just turn on the radio on and turn on you
Plane and you will see how it works...its really easy.
This same idea could be used to create a low rate...or different
expo curves...and since you have two different curves for each mix you
can have one for high throttle, one for low throttle, one for FM1 and
one for all other FM's
This is an extremely powerful tool.
if you have a problem with this call me and I'll walk you
through on a TX at the same time. I know I probably totally confused
you...but its so easy it stupid...You will hit your forehead and go
Duhhhh. Believe me...Its that easy.
....just took a page of words to explain what you were trying to
do.
I could tell RVP how to setup his AILEVATORS too but he doesn't
want to do it that way. And I don't have one of those radios anymore to
walk through it. SO I'll stick with I remember...Its much easier this
way. Besides Ron I think is working on his ACE MicroPro and just
planning to switch to the 9Z. He heard there was thing called PCM and
since everybody else was going to 2.4 he thought this new PCM thing had
pretty much been tested well over the last few years and worked pretty
good. I think he is planning out the transition and wanting to know if
he needs a servo reversing Y harness.
Smile Ron, I was smiling when I wrote that...you know me. I
might not have been the first one to send that shot over your bow, but
mine has happy faces on it!

Now my turn for a JR question this time. I am trying to activate
VTR
for my rudder under code 13 (D/R and EXPO). I can get it
switched to
VTR and 90%, but then I lose the expo that I had programmed in
and it
goes to a linear low rate up till it reaches 90% then kicks to
full.
The problem is that I need the expo also to soften out the
center while
keeping the VTR. Any help??
Thanks
Chris
