Hi Jeff and others..
I have also some minor problems with a wandering rudder. My heli starts to turn clockwise. Every time when I start my Quark after some time (cooldown) I need to put rudder trim to middle or even a bit to left. Then when I start flying, soon I need to start moving slowly my rudder trimmer to right. Usually after I've started to fly it takes about 1 min to fly and then my trimmer is set to all right.
On this case I always take Quark close to me, shut it down and restart it so Gyro will reset it, put trimmer to middle and start flying. After that I usually only need to make small adjustments towards right the rest of my flying time till battery is empty.
I did try few days ago to adjust Rud Nt trim from receiver but it didn't help so now it's back to original factory levels.
All other trimms are about middle, after my first setup, I never touched them. Well no need even
Been thinking if I should try to calibrate my gyro again with calibrating procedures??
Anyone else have this kinda features or behavior?
In generally, I just looooove that heli, it is really nice [8D][8D]
