This is seen on lots of different brands.  Most have a small removable 
plastic stop on each end of the throttle stick travel.  If you really 
feel the need for extra throttle travel and are up to it, you can remove 
these stops.  Just be aware that this can make the stick action at the 
end of the travel a little different.  On my DX 20 this makes the stick 
want to move to and stay at the full throttle end of the travel when you 
approach full throttle.  As I fly mostly large scale sailplanes and use 
the throttle stick for flaps I don't find this a problem.

I think this may have been done to avoid over travel on the throttle 
servo when you add in the trim action.

Your mileage may vary.
