Solved nodeS question

""nodeS" is a stabilizing node. Each node from the hub will attach to this node with a beam. It's mostly legacy and not generally used. Putting 9999 in will disable it." from wiki

Code:

            ["FR", "wheel_FR", "7l", "6l", "c1l",  "7l", 1, {"nodeCoupling:":"ax1r", "torqueCoupling:":"ax1", "torqueArm:":"ax3"}],

I tried attaching a node called "c1l to the hub but it doesn't seem to work.

 

I attached the wheel JBeam too my post ,
