Classic Rotors Museum, Aviation museum at Ramona Airport in Ramona, California, United States.

Classic Rotors is a flying aviation museum at Ramona Airport in Ramona, California, founded in 1992 by Mark DiCiero after he built and learned to fly his own helicopter. It is a non-profit run entirely by volunteers, with no paid staff, and keeps five helicopters in flying condition for air displays. Its collection covers tandem, co-axial, conventional single, intermeshing and tip-powered rotor designs.

The museum was established in 1992 when the founder began building and flying his own helicopter. This personal project grew into a collection that documents how rotorcraft technology developed over time.

The museum's name, Classic Rotors, points to its focus on older rotorcraft rather than modern types. Its stated mission is to preserve rare and vintage rotorcraft as a tribute to the pioneers of vertical flight, and volunteers demonstrate designs such as tandem, co-axial, conventional, sync (intermeshing) and tip-powered rotors.

The museum is run entirely by volunteers, with no paid staff, and is a non-profit organisation. Its five airworthy helicopters are flown in air displays rather than kept only on static show. Check ahead before planning a visit, since display flights depend on the volunteer crew and conditions at Ramona Airport.

The collection displays different rotor types that represent various technical solutions for vertical flight. These contrasting designs help visitors understand why engineers developed different helicopter models to solve different problems.
