[Rex]

Here's a link to Chad's blog.  He talked to Bernd Bernshorner about his motor offset...  there's a short 

blurb about it....

Yes, (del aleman = of the some country I think, maybe German[y]) Gunther Ulsamer  has a carbon fiber strip to reduce turbulence, and something about laminar flow.

Yes, definitely thrust-vectoring on the Plettenberg motor -- looks like there are 7 positions or steps to the vectoring.  I'd bet that really helps in a cross-wind!!!

Also, I didn't notice the deflectors at the bottom of the fuse -- I guess that will counter any roll-coupling effect from the top ones.  I'd love to see an assessment of what they do and how well...

All just further proof that aerobatics competition breeds innovation! :-$

My Portugese is not good at all, but I believe the message says it is Austrian Mayr Gehards, and something about an innovative (????something)  small deflector on the upper part of the vertical stabilizer...Anyone have any idea what they are supposed to do -- what's the benefit, other than increased tail-feather drag???  Does it direct more airflow over the Rudder at the top?  Seems to me that they might add more roll-coupling, what with the increased effect at the TOP of the rudder...
