[NSRCA-discussion] Dual Rates Switches

[Troy Newman]

Your sticks need to be recalibrated.

 

The "flex" in the throttle stick is common and many radios, the 9303
will do this too. Also the Futaba 9Z does this and its common.

 

The new Gimbals on the 12X DON'T have this "flex"

 

When I flew the electric pattern model that "flex" was setup in the
Hacker Comp controller to be my F3A braking.....it worked really well.
Pull the stick to idle and it had an idle set. But it was on the verge
of activating the f3A brake. I would put pressure on the stick and the
brake would activate. It worked really well. Since I only wanted braking
in certain maneuvers at the time.

 

Send the TX off and have the gimbals recalibrated and checked out. They
will fix it up PDQ

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?
