Default Getting tailwag in inverted backwards flying


Im been having a problem with my Trex 500 for couple of months now. The problem is that I get tailwag when I do maneuvers like Hurricane and Funnels. I tried to lower the gain but the problem is still there. I have lowerd the gain untill the tail dos not hold.

Of course I have checked all bearings and the mechanics. No play at all. I use the tourque tube.

One of the strange things is that the problem is not always the same. Sometimes I only get wag in inverted backwards flying and some other times I get it even in hovering. If I get wag in hover, it helps to unplug the battery and replug it. Then it is better again.

I use a Solid-G gyro and a JR8900G servo and Spektrum DX6i transmitter. I have tried diffrent servos but I still got the problem. I have also tried diffrent tailblades and the best so for is Align carbon blades.

Any ideas?

Best regards
