It does not matter which servo is connected first, but if you will do wiring in this way then you can only make mistake in CH1 and CH3.
In the worst case they are swapped and it will work.

Then using Servo reversing in the Setup Wizard is necessary in the most cases.

Ok, sorry for the inconvenience, but again everything is working exactly like it should work until step 9.
Pitch servo (left side No 1 is working, 6 degrees collective ist fine, and at step 9 sticks are reversed.

I need definitely an Futaba expert. I can't believe that the system works correctly with my remote until
I get a proper instruction of a Futaba user/ professional. Have never had a problem like this before.

Hello,

we have very same radio here.
But there is nothing you have to change from default except gyro gain.

So setting Geometry 6° is still ok? Swashplate should tilt in aileron axis only. So with parallel blades to tail boom you will get angle of 6°. After this step it is working all wrong, right?

There should be no 6 deg collective, but cyclic pitch. Elevator servo must be in the middle.

I am afraid but there is really only possibility that servos are reversed or wired incorrectly. Tomorrow I will try to help you step by step.

Of course, the 6 degrees cyclic...
I am always confused in this ;-)

As I told you, everything worked fine till the step 9/10.

I very much appreciate your support!

Hello,

at Step 6, can you verify following things please?

1. when moving collective pitch stick to the highest position, swashplate is going up too. All servos are moving exactly together.
2. when moving elevator stick forward, swashplate is tilting forward.
3. when tilting model to a side with hand, it is trying to keep swashplate level.
4. everything is working at this step correctly, right?

at Step 7:
1. all servo arms should be in the center, swashplate level and in the center and there is 0° between main blades.

at Step 9:
1. can you describe what is wrong there? Because from Step 6 there should be nothing different, except changed subtrims.
Everything in your radio should be still same as at step 6.

What is your model?
What swashplate type you set?

This should be helpful. I am absolutely sure we will find where the problem is - it will be very easy mistake or misunderstanding.

Problem solved. K2 Servo reversed now and everything works perfectly!
Thanks for your help!
