Mudry CAP 20

The CAP 20 is a single seat derivative of the CAP 10.

The CAP 20A is a single seat derivative of the CAP 10 with a no dihedral wing and lengthened landing gear.

The CAP 20B is a modified CAP 20A with new wings and larger ailerons.

CAP-20L

The CAP 20L is a shorter airplane than its predecessor, the 20, and it seems to benefit from a much increased rudder area. Lightened for competition (hence the L designation, for leger), the CAP 20L also has a new wing design.
