Adjustment of tail wheel steering clutch stiffness
To adjust the stiffness of tail wheel steering clutch you need two allen keys (a.k.a. hex-wrench, inbus-key).
On top of the wheel fork you will notice a ring with two tubes welded to each side with hex-bolts inside.
First disconnect the springs at the tubes, then use an allen key into each of these tubes to tighten or
loosen the screw inside. Tightening or loosing, make sure you apply equal number of screw rotations at
both sides. To check if the steering clutch is stiff enough, lift the tail and rotate the fork left and right. At
the end reattach both springs to the tubes again.
