Post subject:  Setup - "half way" stick travel for nick/roll OK?
Hello,
is it OK "on the workbench" if the full deflection of the nick/roll angle (10°) on the rotor head is already reached with approx. 1/2 of the stick travel (nick/roll) of the remote control?
If you now move the sticks further towards 2/2, the nick/roll servos simply remain stationary at 10°.

Or should the full deflection (10°) of the nick/roll angle only be reached at 2/2 of the stick travel? If so, how should I configure this? (Dual rate in the remote control or settings in the Spirit GT?)

Thanks in advance, I have done several searches in the forum but may not have found the right keywords.
Under the following post (in slovensky), a user asks basically the same thing, but has not yet received an answer. viewtopic.php?f=17&t=6072&hilit=stick+travel

Again, thank you for your support in advance

the question is: in setup mode, are all the sticks shown as +/- 100% on full stick travel (or at half stick)? and ist the cycling ring configured correctly?

you cannot check stick travel & FBL deflection on the bench at all. the heli is not moving / flying and in a special mode at this time. real deflections will only show up during flight.

Hello HeliMLM,
thank you for your answer.

Yes, in step5/10 all sticks are shown with +/- 100% when I move them to the related endpoints. In center they are showing 0%.

Yes, if you mean step6/10. The leveling is done by using a swash-leveler, mechanical adjustments of the the rods and measurement of 0° with a electronic tool.

Yes, I understand what you mean.
I'm wondering not about the resulting 10° but more about the situation that not the whole possible moving-way of the sticks is used for movement at this time on the workbench

Kind regards
Carsten

you don't have to ask yourself this question.
The cyclic in flight behaves very well.
You have to fly and select the expo you want on your radio.
To vary speed you changhe
sensor-rotation speed
cyclic and rudder
or if you want to increase the pirouette
advanced-pirouette consistency.

It's normal that it doesn't arrive at the end of the stick.
Fly and you will see that the helicopter flies perfectly.

Hello,

mabe you are misunderstanding something wrong ?
With your stick you give an certain rotation rate - surer or later you will get the full deflection -

The swashplate will in half way of the rate maybe need double the time to get in the endpoint. If you give full stick you will have the half time of it - In other words the swashplate will stand still if you release the stick- you can test this with running motor on the workbench (without blades attached !) and you will see if you release the the stick, the swash will stay in this position - in the air you will see this reaction clearly - the most important with the cyclic ring is that that there is no binding at anytime if you are in minimum, middle and maximum collective stick - you can test this in the three positions as said and then make with your stick movement an full rotation -

Regards

You hit me the right way ... :D

Have a nice week ahead

I'm building an SAB RAW 500 (see signature) and I observe the same as the OP, after having ran through the wizard with my Spirit GT.

With the collective stick and the rudder stick, the servo travel matches the stick movement 1:1, i.e. move from -100% to +100%. With aileron and elevator, the servos stop moving at +/- 30% stick travel, where they reach the configured aileron / elevator range of 10°.

Going on the previous replies, this seems to be normal as the helicopter isn't flying.

Just out of curiosity (and I'm new to this great hobby, so pls forgive me my ignorance), why is that for aileron and elevator, whereas it does match for collective and rudder?

Does this then mean that, during flight, the servo travel will match the stick movement 1:1 for aileron and elevator?

Hello,

the main reason is that Aileron and Elevator are controlled by the Spirit unit. So that all commands are going through many different algorithms + feedback from a motion sensors. Since there is no feedback from the model while sitting at the bench you will only observe what could look like odd behavior. But when model is flying it is reacting to all the commands and it does what you would expect.
Collective Pitch is not processed in any way and does not require any feedback, so you can see it somehow correctly.

Thank you very much for taking to time to provide these insights Tomas, it is much appreciated!!
