Default Question about STICK SETTING

Hello,
I have upgraded my 14MZ radio software and found the new function STICK SETTING where it is possible to
set the Sticks sensitivity/response parameter 1-32 as well as to set the STICK HISTERISIS parameter 0-32.
It is says that like other setups it is possible to allow a different Stick settings for each condition.
Up until now I was adjusting the sticks response by adjusting the Graph, Rates and Expo.

My Questions:
1) In what manners the Stick-Setting response adjustments is different from adjusting the Graph, Rates and Expo.
2) Any practical examples of Stick Setting response function usage rather then adjusting Graph, Rates and Expo
3) Any practical examples of Stick Histerisis function.

Very best regards

Default RE: Question about STICK SETTING

The stick setting menu came about from requests by F3A Pattern fliers so that they could fine-tune the way the transmitter works and feels.

"Stick Response" sets how fast the system responds to stick input. Higher values slow down the response. You use this to adjust the "feel" of the transmitter to suit you. The default setting is about right for just about everyone.

"Hysteresis" sets how much you have to move the stick before the system starts to respond. It adds a bit of "slop" in the center. The higher the number, the more hysteresis you set. Competition Pattern fliers use hysteresis so that they can hold a stick position without causing changes to the flight control as they make the small, involuntary movements everyone has when they try to hold the stick at a given deflection.

The way you describe Hysteresis sounds just like adjusting the deadband around the center yet they have given it an exotic name like Hystersis which implies to me that it may be something more. Also your example seems to imply that this deadband is applied even when the stick is not at center.

Could you amplify the discssion a little more ?

Thank you very much for the reply.
OKAY good.... this is getting closer as I mostly flying F3A.
SO if I understand the Stick setting:

1) Old way was to adjust the resolution response of the stick by changing the Servo travel while the H/W stick resolution is fixed.
This is done by changing travel Rates etc.

2) With Stick Setting is possible to adjust the stick resolution response by changing the H/W resolution where the Travel is fixed.

The only question I have is what aplicastions this is good for or in F3A in what maneuvers or conditions this is practical?

As to Hysteresis.
See attached picture of Hysteresis definition. To the best of my understanding of your reply What you have describing is an offset around the 0 point when can be achieved by OFFSET function or by EXPO or customized graph.
The definition of the Hysteresis is different "response curve" going out and going back in, or like the picture shows:
Different "response curve" on Loading and other curve back on unloading.
IS THAT THE CASE? (If yes this is really great...)

Thanks in advance for your reply

I guess it's a matter of personal preference, but frankly, I don't see why anyone doing precision aerobatics would want this.
We pay a lot of money for radio equipment with increased resolution, less deadband, and less slop.

Default RE: Question about STICK SETTING

The stick response puts a slight delay in when the transmitter starts the move the control signal. I guess this is to simulate older transmitters that some fliers are used to. Futaba listens to F3A and F3C pilots when planning features for their transmitters.

"Hysteresis" is basically deadband upon stick movement. It is active at all stick ranges. You could, if you deisire (though why is a good question), set the sticks so that you have very visible movement before any control will move. This applies to the stick, and would be analogous to having "play" in the steering wheel of an automobile. You have to move the wheel a certain distance before any steering would take effect, and then have to move through the deadband to steer the other way.

These things may be developed from the habits of top Japanese model pilots. I do know that the hysteresis is used by F3A pilots to control collateral stick movement. For example, if you are performing a slow roll, and have to hold 1/2-stick movement, hysteresis prevents the transmitter from moving the servos when you make the inevitable small movements while you try to hold the 1/2-stick deflection. Other pilots will set a rate that allows them to slam the stick all the way to the physical stop and have the ailerons at the slow-roll setting. It depends upon style. However, if you set a rate, it's harder to adjust the roll rate to suit the judges when you discover that their "slow roll" is faster/slower than your "slow roll" and on, and on, and on.

All part of getting the transmitter set up so that it is part YOU! So many programming options get it customized to suit you, and you alone. Top-level, world-class competitive pilots will use every edge they can get, and these features are some of them.

THANK YOU SIR FOR DETAILED RESPONSE.
IT IS VERY CLEAR NOT. I SURE FAR FROM BEING A TOP F3A PILOTS BUT I AGREE WITH YOUR FINAL
STATEMENT AS TO USING ANY POSSIABLE FEATURE
TO MAKE LIFE EASY. THIS IS WHY THE 14MZ IS SO GREAT!!!!
THANKS AGAIN
AMRAM
