[NSRCA-discussion] FAT Rudder

[Phil Spelt]

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! :-$
