a.  Photo of bulkhead fittings and aileron and flap servo extensions in place.  
b.  For the brakes and retracts we suggest that you purchase 3 different colored air lines to 

keep things organized. We suggest 1/8” or 3mm line. Either of these lines work well with 
Festo 3mm fittings.  

c.  Purchase 6 of the Festo 3mm bulkhead fittings. These go through the bulkhead in front 

of the wing. The holes are there already. This then gives you quick disconnects for all 6 
lines when you remove the center section of the wing from the fuselage. 

d.  We number the air lines that plug into the bulkhead fittings for better organization.
