reading here, trying to find info on tail wag. I have not experienced this in a long time. Everything is nice and free, no slop, GY601 setup like I have in the past. (mounted in back) turned gain down to 32% Very slight wag now and then, but when you go inverted, no matter how gentle
you do it. It starts wagging up a storm. The headspeed is staying constant, so I don't think that is an issues. This thing flys great, but this is starting to get me down, any ideas to try, I have pretty much tried everything I know of. Thanks for any help.

I had the same problem but found that the more fuel i ran through it the better it got when your engine is run in proply it should be fine

I forgot about this, I don't remember what I did to fix it. I tried a couple things, and took it out to the field, plew perfect, and no wags since..

Bob the Rex's have a powerfull tail and therefore good mechanical gain that reqiures you to keep the servo horn a little shorter than normal and combined with a lower than normal gyro gain%

About one hole in than your normal position on the servo horn

I forget what I did, but I am running 32% gain on the GY601( I had already lowered that) And it works awsome, with not a hing of wag. At first I was thinking it was the thrust bearings in the tail, but this is by far my favorite heli now

Thats what I did! I moved the sensor up front. And I "mounted" the tail rod guides to the boom.
