Graeme/Jon, It is not impossible to imagine that a tool or some other
foreign object has got misplaced around the CS10 pitch torque tube or
some other part of the the pitch control system in such a way as to
limit movement, but measuring tail plane travel The acceptable limits
for the movement of the tail plane from its neutral position are:+12 to
13 degrees & - 4 to 5 degrees. If you are not getting that range you
have a problem!

component pivoting within the torque tube bearings, the limits of movement being
the mass balance weight striking the top and bottom of its vertical guides
in the fuselage respectively. These limits of movement of the weight are the
elevator control stops, there are no other stops anywhere else. When the weight
is fully up (against the inside of the fuselage top) then the tailplane will
be in its full down elevator position and when the weight is fully down (on
its lower stop that is built into the tower just above the elevator control 
torque
tube) then the tailplane will be in its full up elevator postion. The tailplane/
mass balance weight assembly must be able to run fully and freely between
these two stops and the control surface deflection must be correct as per
the manual at each limit. As David says, if you are in any doubt about the 
system
if only for piece of mind you should have a jo!

if you do find anything - or hopefully if you find everything is ok.....!

be getting too slow on final approach and effectively stalling it in? Have
you changed anything in your ASI system that could perhaps cause it to overread
and therefore you might not be as fast as you might think? Sorry again for
speculation - just a thought!
