Hello,

i have a problem with my Goblin Fireball with Spirt RS Version 3.5.0.
If I turn rudder to the right (clockwise rotation of the helicopter) the Fireball starts to move forward (as if i give nick forward input).
If I turn to the left (counterclockwise) the Fireball starts to mov backwards (as if I give nick back input).

If I hover without rudder input the Fireball stays stable without any unwanted movement (only normal drifting due to wind).

I have this problem since I updated to Version 3.5.0 after rebuilding from crash (see https://www.spirit-system.com/phpBB3/vi ... ash#p39576). I did not change any settings.

My other Helis with Spirit GT (Goblin RAW 700 and Thundertiger E550) with older firmware version don't have this problem. And all of my helis with other FBL also don't have this problem.

Enclosed my saved settings.
Any hints to stop this behavior are welcome.

Thanks
Gerhard

Hello,

when moving with rudder stick check diagnostic tab in the software. There should be no other movement in other channels.

Either servos are connected incorrectly or thete is some mix in the radio.

Thank you for your input.

I checked the servo monitor in my Jeti DS-12 and in the diagnostic tab in Spirit Software:
- In Jeti Servomonitor it moves from -100% (left) to +100% (right) without any other channel changing
- There is no mixer in the configuration of the model
- In the diagnostic tab of the spirit it shows -103% (left) to 96% (right).
- No changes on nick or roll in the diagnostic tab on rudder change

If I move rudder with the heli on the ground the swashplate does not move.
I only see the problem when I am hovering and give rudder input.
I tried to fly around and the heli flow normal with the only exception that I have to make small corrections on nick when flying a curve.

I also checked the configuration of the spirit as you suggested:
- Horizontal 180° (Connections locking forward)
- CCPM 120° (CH1 left front; CH3 right front; CH2 back) - Servos connected as described here

Thank you
Gerhard
Kind regards
