None.  I ran brake lines and pitot line down the elevator slot core.  They don't weaken the canard structure and you can always inspect the lines by removing the elevators. 

Just my $0.02.

Dear Q-Team,

in the next step I would like to cut out the canard and wing units based on the blue foam.

Which further openings in the wings or canard from your personal experience you would place? For braking lines? For wiring? In which position you would place the further openings? 

I would like to benefit from your experience and introduce the right openings in the wing and the canard right from the start. 

Please find below some short cuts from the foam cut software whiteout any additional openings in the canard (Bl10 to BL10).

Best regards 

Eugen
