There are 2 bags under the seat of decent volume that come standard.
For another $275, you can get 3 more bags. Two thin bags that stuff in the back of front seat in the arm rest coves.
One bag that attaches to the back of back seat.
Further, we are working on a belly fiberglass attachment that will go under the belly under back seat (close to CG) that can be attached or taken off and can be painted in the same color code as your gyroplane. Its price is not yet decided but our composite shop has started work on making the mold.
