Yes, there has been a change in the Stick pots on the 14MZ, as they found the
original ones did not hold up. There is a conversion available to fix this
problem. You should not have any problem with Hobbico Service fixing it for
you. However, we can also do it here. They may do it for free as a warranty
issue, however.<o:p></o:p></span></font></p>

Futaba 14MZ glitch</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

<p class=MsoNormal><font size=1 color=black face=Arial><span style='font-size:
9.0pt;font-family:Arial;color:black'>To all,<br>
<br>
Two of my friends from <st1:place w:st="on">Hong Kong</st1:place> informed me
that their 14MZ has developed what the the Futaba Japan called a "Stick
Volume" problem. You can be flying along without giving any input to
any of the control, but suddenly, there can be a twitch on any of the moving
surfaces, as if you give the stick a quick jerking movement. One of my friend
had it to the rudder, and the other on the aileron. They sent it back to Futaba
<st1:country-region w:st="on"><st1:place w:st="on">Japan</st1:place></st1:country-region>
and got it fixed, explanation from Futaba was a wear and tear problem on the
stick control.<br>
<br>
I've been using my 14MZ for over a year now, and I had the same thing happen to
my aileron started about a month ago. At first, I thought it was an old ail
servo, I changed both of them and flew it for another 20 flights without any
issues. Then, I switched to another plane with brand new aileron servos a few
days ago, and the same issue resurfaced, and the occurance gets more and more
frequnt. <br>
<br>
This morning, I was practicing the P-09 sequence with my friend Don Atwood. As
I was pulling the plane into the stall turn, it started to twitch on the up
line. I then pulled the plane into the next maneuver - top hat with 4 of 8 - it
twitched again on the down line. It never went into a complete lock-out, but
just a quick twitch on the ail. <br>
<br>
After I landed, I was able to duplicate the same movement on the aileron. I
moved the stick back and forth a few times, as soon as I let go of the stick,
within a split second, both aileron will twitch a few times and then stopped. <br>
<br>
As far as I know, the 14MZ Tx does not have atick pots any more, it has some
kind of an encoder, similar to a - fly by wire - system on the modern jet
liners? The encoder is suppose to detect the amount of input onto the stick and
feed the signal to the servos?<br>
<br>
Here are my questions:-<br>
<br>
Am I correct on the encoding system? <br>
<br>
Does anyone on the list experienced the same issue? <br>
<br>
Does this only occur to the 14MZ, or, other models with the similar
encoding system. Particularly with the 2048 resolution?<br>
<br>
When I send it to Great Planes for service, will they be able to identify the
problem easily with an electronic scope?<br>
<br>
Thanks in advance to all.<br>
