now when you fit your cockpit into the fuselage...it's always a good idea to dry fit everything and in this case check the wing fit too....
In this case it is not as good as I thought it would be...have glued the fuselage without glueing the cockpit at all, it simply went in real clean and snug thus allowing the opportunity to 'spread' the fuselage slightly to get a nice clean fit to the wings....to be done next in the process.
Sometimes you can and should glue your cockpit to one side of fuselage and not the other so you still have the back up of spreading the fuselage if necessary.....
So just in case some didn't download the 'Spacer' PDF here it is again for your reference and use.
