XK K120 and Taranis QX7

I am using a Taranis QX7 with Jumper JP4in1 module to fly a XK K120. It is flying very smooth. I configure CH5 as gyro rate setting. When I am switching to 3D mode output of CH5 showing 1120 msec. But the heli won't be able to fly 3D rather it seems to level itself when I steers it for invert flight. Where am I missing? All suggestions are welcome.

Ok, I figured out the solution. CH5 1900 msec is 3D mode not 1120 msec. The helicopter is flying nice.

Hi mdxp67,
My channel settings are as follows
channel order AETR (mode2)
Aileron and elevator 25% expo
all channels end point +/- 100% (you may need to reverse some channels please check your self, mine rudder and elevator reversed)
CH5 is configured with SWA, UP 6G (output 1120 msec) , Middle NONE, Down 3D (1900 msec)

in mixture page CH6 (Pitch) source is CH3 (Throttle)
I have no normal mode as the cyclic are not very responsive in low head speed. I use a flat 100% throttle curve.

in special function screen set SWF DOWN to override CH3 (Throttle to -103%) it will be throttle hold.

My pitch curve setting is -40 , -20, 0, 20, 40. You can try this or modify to match your flying style. I fly mild 3D.
