The  first  of  its  kind,  interchangeable  modular  engineered  helicopter  to 
accommodate the beginner to a FAI expert… 
 
An idea in 1994 to manufacture an interchangeable, modular helicopter, led to 
the  research  and  development  in  1995.    Focusing  on  quality,  engineering 
details,  and  price,  a  prototype  was  produced.    After  extensive  test  flights  and 
fine-tuning, the INTREPID HELICOPTER is now what you see today.  The first 
of its kind, strength combined with simplicity for easy maintenance and flying. 
 
Although  beginners  can successfully  build  and  fly  their  INTREPID,  the  process 
can be made significantly easier with  the help of an experienced modeler and 
instructor pilot.  We recommend that all  beginners join the Academy of Model 
Aeronautics (AMA).  The AMA is a non-profit organization that provides services 
for modelers.  The AMA can help you locate a model aircraft club in your area 
with  an  instructor  pilot  (you  can  also  check  with  your  local  hobby  shop).  
Membership benefits include a monthly magazine and liability insurance.  Many 
flying clubs require an AMA modeler’s license to operate a model on their flying 
field.  For more information on the AMA contact:
