Hi Ragz.
The article is coming up in the next RCJI publication.
I also made up a thread here:

In summary:
Unchanged performance ( compared to the latest generation P-200s ) which remains one of the best available on the market in terms of acceleration.
Improved reliability and engine strength ( which was already very good as well )
Perfectly predicable kero start
New battery and engine cable
