The Chambers R-1 racing aircraft was designed and built by American engineer Russell Chambers specifically for participation in the National Air Races. This single-seat, mid-wing monoplane was powered by a 90 hp Menasco BS-4 engine, crafted for high-speed aerial competition.
Innovative Design and Engineering
Russell Chambers envisioned the R-1 as a competitive machine, aiming to optimize speed and agility. Its construction emphasized simplicity and efficiency, common characteristics in racing planes of that era striving to maximize performance with limited engine power.
The Unique “Chambermaid” and its Tragic Fate
The sole example of the aircraft, bearing the registration NX95Y and christened “Chambermaid,” was entered into the 1938 National Air Races. However, its participation was tragically brief. During the qualification round, the “Chambermaid” crashed upon landing. Russell Chambers succumbed to the injuries sustained in the impact, marking a sad end for both the innovative designer and his creation.
