[NSRCA-discussion] Dual Rates Switches

[Jon Lowe]

Had the same problem.  Sent it off to Horizon, and they recalibrated 
it.  Problem solved.

My travel adjustments on all channels are
less than 100%.  The dual rates are 100% on high rates and 50% on low
rates.  The expos are 50% on high rates and 25% on low rates.  I don’t
believe I have excessive subtrim on any of the channels.  I did notice
this summer an issue with the throttle stick.  When the stick is all the
way down I could make the rpms on my YS decrease another 200 rpm or so 
by
putting down pressure on the throttle stick.  Could this be a sign of 
what
you were talking about?  I had the radio serviced 2 years ago.



 



Thanks

Possible
solutions…..



 



Travel
Volume is really high and the rates are set really low. Like Travel 
Adjust is
at 150% but the D/R is set at 30% with large amounts of expo. And can 
even be
complicated by extreme amounts of subtrim too.



Although
this is probably not the issue I have seen it happen on well worn TX’s
meaning the Gimbal pots are worn/bad.



If
they getting really bad then it happens even when the travel adjust and 
d/r are
in reasonable numbers.



 



Another
option while I have not seen it on the JR radios is that the pot has 
slipped on
the gimbal so center is not the same center the gimbal was calibrated 
too. This
happened on the Futaba 9Z radios all the time. Never had the problem 
with the
JR 10x like this though.



 



I
would ask how long it has been since the radio was sent in for service? 
If
it’s over 3years well it’s past time.



 



The
TX pots can get worn over time like a servo pot. The TX just doesn’t 
have
the vibration to accelerate the wear, but they can get dirty and worn 
and this
affects accuracy.

This weekend I was trying to setup a
park flyer on my 10X radio.  I noticed that the center changed on the
elevator, rudder and aileron when I flipped the dual rate switches.  
Just
to clarify, flipping the elevator dual rate switch had no effect on the 
rudder
and aileron just on the elevator centering.  Ditto on the rudder and the
aileron.  Got any ideas what is going on?
