Finally, it is necessary to make the mold of the front gear door using the shape of the gondola for it. Once the final piece of fiber has been obtained, the hollow provided between the frames of the fuselage is cut with a scalpel and the piece is adjusted to its limits. I recommend reinforcing the laminate with carbon strips to get resistance without penalizing the weight, since its length makes it very flexible; In addition, its interior face has been double-walled with little balsa formers, making it very robust and lightweight, allowing the realization of interior details.

The aerodynamic "kármán" (wing fillet) is obtained on strips of balsa of different thickness, sanded with care to obtain its special shape. The transition of the sides of the gondola with the rest of the wing is made with light mastic. The flaps are carved in solid balsa.
