In your annotations of the picture from the plans, you have misidentified the location of the main wing. The main wing resides in the bay just forward of where your arrow points, where the fuselage side is already contoured as a saddle to cradle the underside of the wing. This also should answer your question about the canard and main wing shapes – yes, they’re already supposed to be cut into the foam before the inside of the fuselage is glassed (I think).

Thank you very much for your response. That will help me again.
So another question about the fuselage side situation. Please find in the attachment a picture of the fuselage side after glassing, come from the Q1 construction manual.
The questions may sound a bit silly, but for my full understanding below some questions about the fuselage. Maybe I should just put the construction manual aside for two days and think about the process again. I feel like I've gone through the process a hundred times in my head……..
a) Should the shape of the canard and from the wing into the fuselage side be cut out before laminating with fiberglass or is that done later? Judging from the picture in the builders manual, the shape of the canard and wing are not cut out before laminating with fiberglass (see attachment). Am I correct?
b) Should laminating from the inside fuselage side with fiberglass be done on a straight surface? Will the fuselage side still be supple enough after laminating with fiberglass on one side that it will still be possible to contact the fuselage bottom during assembly? Or should the fuselage side also be done on a defenestrated curved run like the fuselage bottom? This is not yet completely clear to me.
c) Should the laminate, after the resin has been applied, still be covered with peel ply, with the aim of achieving a rough surface for the subsequent bonding? Or is it sufficient to line the contact points of the frames with the peel ply? Or simply leave them out completely and just grind the contact points?
Thank you very much for your support.
