I have a 66 E, so the wing leveler is different for the models done after 66, but I don't know what the problem is.
My plane drifts to the right always. I have to turn my adjuster knob all the way left and it sometimes doesn't go right, but usually still drifts. If I turn it right, it makes a standard rate turn right.
I have replaced the servos in all four locations. I have vacuum tested the sevos and the tubing with no leaks. I have vacuum tested the lines coming from the adjustment knob and they pass with flying colors.
I then sent my controller back to britton and got a new one, because that had to be the reason. Well it didn't change anything. Still does the same thing. I then had the rigging checked on the plane and it was perfectly rigged.
I changed the tubing to see if the system would switch and pull left, well that didn't work either, when I adjusted to the left (remember it is now opposite) it made a standard rate turn right and when I did the opposite, it just went straight.
I did a vacuum test of the knob controller and it acts exactly the same depending of the way i adjust, so it seems to be working fine. So every component has been checked and is operating correctly. so it seems. The only thing i didn't do was switch the servos on both wings, because that is a bigger job than I wanted to do.
I am of the opinion it is not a wing leveler problem, but somehow mechanical on my plane, but I don't know. I don't know how many hours I have spent on this, and all I get is more questions.
Thanks for your guys help.
