WARNING!  THIS IS NOT A TOY!

Flying  machines  of  any  form,  either  model-size  or  full-size,  are  not  toys!
Because of the speeds that airplanes must achieve in order to fly, they are
capable of causing serious bodily harm and property damage if they crash.

IT  IS YOUR  RESPONSIBILITY  AND YOURS  ALONE

to  assemble  this

model airplane correctly according to the plans and instructions, to ground
test  the  finished  model  before  each  flight  to  make  sure  it  is  completely 
airworthy,  and  to  always  fly  your  model  in  a  safe  location  and  in  a  safe 
manner.  The first test flights should only be made by an experienced R/C
flyer, familiar with high performance R/C aircraft.

JOIN THE AMA

The governing body for radio-control model airplanes in the United States
is the ACADEMY OF MODEL AERONAUTICS, commonly called the AMA.
The AMA SAFETY CODE provides guidelines for the safe operation of R/C
model airplanes.  While AMA membership is not necessarily mandatory, it
is  required  by  most  R/C  flying  clubs  in  the  U.S.  and  provides  you  with
important  liability  insurance  in  case  your  R/C  model  should  ever  cause
serious property damage or personal injury to someone else.
