Kingsley,
Look on the diagram for the tail wheel installation Chapter 23M-7 figure 
10.  There are some who have expressed interest in reducing the tail 
wheel from the 9.25 inches to say 7 inches to get a higher deck angle.
Do not do this as the geometry of the tail wheel is changed 
significantly.  Stick with the manual or buy and test your own tail 
wheel and set the geometry with this new gear to allow the rudder to 
drive the tail wheel, prevent excess castor and proper rudder to 
tailwheel geometry so when the tail wheel turns, it does not jam or 
cause the tail wheel cable to pull the rudder uncommanded...

Regards,
Bud

  Bud,

  You said:
  "Should the tail wheel spring arm be installed about 2 inches higher 
than the manual described, the tail wheel geometry will actually drive 
the rudder and flick the tail wheel around when passing 60 degrees 
causing the tail wheel to restrict rudder movement and a loss of control 
will occur."

  Sorry but I'm not sure exactly what you mean . . . .  are you saying 
that if the rear most part of the tailwheel spring is higher (rear of 
fuselage lower) or rear most part of the tailwheel sping is lower (rear 
of fuselage higher) ?

  Thanks
