Here is my local config for the p51d yasim propeller.  Most of these values
are pretty much on target according to actual specifications.  The problem is
that it "appears" to not produce sufficient thrust.

Is it possible that we have a flaw in the thrust calculation?  Does anyone
have any actual data for p51-D thrust?


<propeller   x="-0.75" y="0" z="0"
           radius="1.75" 
           mass="1690" moment="94.5"
           cruise-alt="21400" cruise-power="1470"
           cruise-speed="380" cruise-rpm="1200"
           gear-ratio="0.479"
           manual-pitch="true" >
  <actionpt x="-1.25" y="0" z="0"/>
  <control-input axis="/controls/engines/engine[0]/propeller-pitch"
control="PROPPITCH"
                 src0="0" src1="1" dst0="0.40" dst1="0.82"/>
</propeller>


Thanks,

Jim
