How Much Cable Play between Rudder and Tailwheel in Q2?

Joe Hood
 

I have about a half inch of play in relationship to my tail wheel. This is still pre-Six pack, so cable comes from wheel to rudder. I haven't figured out where in the plans this number might be, anyone know?

Is thy that with the tail wheel off of the ground?  The tail spring flex will perhaps make it tighter when the load is off.  You can take the slack off the cable by putting a couple of springs from one cable to the other which pulls them together in the middle.  As you push the rudder peddles left and right the springs move with them.  Hope this is clear as mud.

Oh, that makes sense: I did have weight on the tailwheel. And the build instructions do show springs wrapped around. 

Thanks!

Bruce is correct, you have to adjust the cable to the rudder with the tailwheel spring unloaded. If the cable is too loose, you can encounter rudder flutter at the higher speeds.  This is unnerving, as it shakes the crap out of the entire aircraft.

Joe, take a look at my recent Q-Tour video. The stock tailwheel/cable setup is not good.  I talk about it a little here and how I improved it.  https://youtu.be/yAqjcTAcHTw?t=1758
The stock method is a shitty design.

Regards,

Sam

I intend to complete the six pack, once I get the plane back to Michigan.

I have to complete the six pack too.

Sam:
Do you have instructions/drawings/parts list for your cable splitter in the files section somewhere, or on your blog? Might be an easier retrofit on a completed bird.

No destructions needed, this photo shows all.  The turnbuckle cable goes to the rudder bellcrank.

Here’s another cable option that allows for differential between rudder and tailwheel but Sam’s
set up is a lot easier to install especially on a finished airplane. Like he said, no destruction.  (This is one of the six pack mods). I think this mod is like dual finger brakes vs dual toe brakes, it’s a matter of individual taste. They both accomplish the same thing.

Sam, is that plate aluminum or steel? Thickness?
