is there a modification needed for the knife tail wheel assembly?
 

from the plans there looks to be a long wire hanging under the rudder for the tail wheel..
is that going to last or will I be reshaping it after each langing?
anyone have a suggestion here?
thanks

The Sig Something Extra has the same setup.

My first knife used just the tail skid with no wheel (flew off grass)and it lasted in the same shape to this day roughly 5 or 6 flying seasons with plenty of rough landings
unless they changed the wire from the eariler kits it should be fine

I used a Sullivan tail wheel bracket for my knife.

Works for me. I fly off grass and wanted a little better ground handling than my Magic which just had the wire.
