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 com-
pletely 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 opera-
tion 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.
