  Tim, this might be of interest (from icare-rc.com)

  Bernd Beschorner, is German Champion in Class F3A and made 5th place at 
  Euopean Championship in Lisbon (Spain) with the same a setup 
  (Plettenberg Xtra 25-13 -AG), having so flown the first electric direct 
  drive setup making the top places!

  In recent FMT (German modelling magazine) (4) four F3A setup were tested 
  and compared. The Plettenberg Xtra achieved best overall performance. 
  Comparative test was made with Xtra 25-13, Torcman TM430-30-30, Lehner 
  2230-16-13 PG6:1 and Hacker C50-Acro PG6.7:1. *Plettenberg Xtra 25-13* 
  achieved highest power output, lowest weight, lowest noise and stayed 
  the coolest during tests at 40 °C proving it's very high efficiency.

  Christophe Paysant Leroux has chosen Plettenberg *Xtra 25-13* for his 
  new Oxalys F3A.
