Next step is the Building of the Sponsons

The Sponsons on the full size helicopter are located on both sides of the fuselage and used for two main things - Main landing gear are located on the back of the sponsons and folding forward. The front of the sponson (two-thirds the size) contain a large fuel tanks made of rubber
The sponsons on the model are about 66 cm in length.

The construction of the sponsons plug is made the same way as the fus. I built a wooden skeleton. The ribs are copied from drawings. I fill the gaps with foam. After sanding to the final shape, the plug is covered with fiberglass.
