Slowly increasing left yaw/spin

Out of the box, both of my helicopters tend to yaw/spin to the left.  I can control it using the trim adjustment, but find myself slowly adding more right trim as the flight progresses.  Anyone else experience this issue?

Yep, both of my birds do the same thing as the battery runs down, they yaw right.  I find that by the end of the flight I am at the extreme adjustment.  I notice it as it becomes increasingly difficult to turn right.

I would agree, it seems to be a trend as the batteries run low. But I have found in "healthy" birds that I am only making very minor adjustments. In birds that have a weak motor (either A or B), or are showing more gear wear on one set (A versus B) than you generally have to start with a more aggressive correction and by the end of the flight you may have to correct all the way left or right on the knob.

Has anyone encountered an almost uncontrollable yaw after a bad crash that is not the result of inoperable motors or gears? One of my helis spins like it is possessed counterclockwise, which when corrected using the stick begins it spinning wildly the other way. It's actually quite comical and fun to fly, but I would love to correct it. I'm thinking PCB replacement.

Shouldn't the gyro correct inadvertent yaw?
