Hmm, for me the rudder is reversed now and I can't fix it via the settings program (invert axis still seems broken).
What I found though is in the settings text file.

For keyboard settings, there's ususally two axis entries; eg (though I'm not sure the names are exxactly like this, writing from memory):
RPC_MIXTURE_P=key_equal
RPC_MIXTURE_N=key_minus
RPC_MIXTURE_P=joy0_axis_T

I figured the P and N stand for positive and negative respectively.
So I just scrolled to the rudder section, and replaced:
RPC_YAW_P=joy1_axis_X
with:
RPC_YAW_N=joy1_axis_X
and my rudder pedals were reversed. The same thing goes for other axis', eg. throttle, if you want it reversed, just replace P with N in the settings config file.

Rousing music and a rousing video Vladimir!

Should have titled it "Flight Of the Vultures" though.

Instead of rudder pedals, you can twist the joystick, am I correct??

Correct.
