Congratulations on your acquisition of Maxford USA’s version of the Hughes H-1 from the Golden Age  
of Aviation – the 20-year period between the end of World War I and the beginning of World War II. 

The H-1 was Hughes Aircraft Company’s first aircraft.  Though originally conceived simply for speed, the H-1 had many 
new features that influenced the design of high-performance aircraft for years, including … 

 

Retractable landing gear. 

 

Gently curving wing fillets between the wing and the fuselage to help 
stabilize airflow, reduce drag, and prevent potentially dangerous eddying 
and buffeting. 

 

Rivets and joints made flush with the aircraft’s aluminum skin. 

 

The ailerons could be drooped 15 degrees when the flaps were fully 
extended, improving lift along the full length of the wing for takeoffs 
and landings. 

With Howard Hughes at the controls in 1935, the H-1 succeeded in breaking 
the world land-plane speed record, clocking 352 mph over a specially 
instrumented course near Santa Ana, California.  Hughes then set a 
transcontinental speed record, flying his H-1 at an average speed of 322 mph, 
non-stop from Los Angeles to New York City in 1937.  The original H-1 was 
donated to the Smithsonian National Air and Space Museum in 1975, where it 
remains on display in the Golden Age of Flight gallery. 

After nearly 2 years in development, this model of the H-1 is smooth and stable at both low and high speeds.  True to the 
original, all of the rudder, elevator and aileron linkages are fully concealed within the fuselage, giving this model a more 
scale-like, streamlined appearance.  This Hughes H-1 model also includes a spring-loaded tail wheel, magnetic battery hatch, 
scale fixed landing gear plus the option to easily add retractable landing gear, and a new “Max Cowling” fiberglass cowl.  
(Developed by Maxford USA for RC airplanes, "Max Cowling” is a new technology to preserve the cowl’s smooth, scale-like 
appearance and to make removal and reattachment quick and easy.  With this technology, just push and twist, and the cowl is 
safely secured with 3 screws and a magnet.) 

Enjoy the pride of ownership and the joy of flying this high-quality model of the famous Hughes H-1

IMPORTANT SAFETY PRECAUTIONS 

TO PROTECT YOUR MODEL, YOURSELF & OTHERS 

1.

 

This product should not be considered a toy, but rather a sophisticated working model that functions much like a full-scale 

airplane.  Because of its performance capabilities, this product, if not assembled and operated correctly, could cause injury 
to you or spectators and damage to property.  Maxford USA provides you with a high-quality, thoroughly tested model 
airplane kit with assembly instructions.  However, the quality and capabilities of your finished model airplane depends on 
how you build it, and your safety depends on how you use and fly it.  Any testing or flying of this model airplane is done 
entirely at your own risk. 

2.

 

Assemble the model airplane according to the instructions.  Take time to build it STRAIGHT, TRUE and STRONG.  We 
recommend that you do not alter or modify the model, as doing so may result in an unsafe or unworkable model.  In a few 
cases the instructions may differ slightly from the photos.  In those instances the written instructions should be considered 
as correct.  If you have any question about the instructions, before you proceed with assembly of this product, contact us at 
(562) 802-0680, Monday through Friday, except national holidays, between 8:30 AM to 5 PM Pacific time.
