Bill,

There is polar data from many of the Amel models in the PredictWind archive, including the 54.

I can not comment on the validity of the data for the 54, but based on the version they have available for the 53, I’d put VERY little faith in its accuracy.  They look like they were generated by a very simplistic VPP, but it might be better than nothing for a non-critical use.
