Hello everyone. Another new guy.

Ok. I have the T-REX 450 S but haven't logged in that many hours with it yet. I can hover and do some simple directional flights though.

Now the problem... My heli has a tendency to Yaw right. I use the GY401 and have to set to 35% gain. It's frustrating the sanity out of me.

My friend suggested that I do the "Off-Setting" on the tail blade, where by I set the resting position of the tail rotor slightly off true center. He suggests I wind out the linkage by three revolutions.

I followed his advice and tried it but to no avail. Crying or Very sad

So I was wondering if I did it correctly or if there's another way to do it.

Please help...

I've also heard of that concept "offsetting" but never had to do it on my heli. You might have to do it on yours, I'm not sure. But one thing I want to remark. The gyro gain on your T-REX is pretty low, and when that's so the tail won't hold so solid. So that could be why your Heli yaws.

It's hard to get the gain setting up without wagging the tail, maybe try to change to blade as that's what my friend did on his helicopter and it got much more stable.
