I have been away from the hobby for a few years. I'm retired and back at it.I have a Spectrum Dx6i and Blade 120sr. I have created a new setup with help from you tube. I have no left rudder control. When I use right rudder it spins around like a top. Is this a 5-1 controller problem? Tweaking trvl adj, sub-trim, trim no help.
How does the spectrum 5-1 control the rudder?

Check that the tail rotor is not on backwards, from memory that used to have that effect, as it has an airfoil section to assist counteracting torque.

I looked at it, It can't be put on backwards. One end is a smaller diameter and won't allow you to put it on backwards.

I have a print out from years ago (rcheliworx). It explains how this model yaws. I didn't have the blades installed(rebuilding). That must be why I have this problem. I'll post again if I still have issues. Thanks

When you use the Right rudder which way does it spin Left or right ? you didn't say.
If you have some video it would help a lot, I'm working on memory here, I sold the 2 x 120-SRs about 10 years ago.
Have you tried reversing the Rudder servo or Gyro servo or both.

Thanks. I put it all back together and tail is fine. I now have a lean to the right as I throttle up. May need some tweaks in the radio. I know my fleet is old. I'm looking to upgrade. I'm looking at DX6e and Blade 150 S and a 120 S2. Still learning.
