THE LOOP.

This is a good first stunt. The model

starts flying straight and level into the wind, then
pulls up into a smooth, round loop. The up and down
portion should be straight, without the plane falling
off to the right or left, and the speed should be con-
stant. As the plane finishes the loop, it pulls out
straight and level, at the same heading and altitude
as when it entered the maneuver.

BEGINNING AEROBATICS

Almost all maneuvers are a combination of loops
and rolls, so if you can do these two things, you're off
to a good start!  We highly recommend the book

Flight Training Course, Volume II

, published by

R/C Modeler Magazine.  

Some of the following is

taken from this manual, with the gracious permission
of the magazine.

Above all, remember that top gun aerobatics are the
result of practice.  The crisp, graceful movements
come from the pilot's willingness to do and do it again.
Don't give up; practice really does make perfect!

Which side is up?

Learning to recognize which side

is up may sound foolish, but many a plane has bitten
the dust because the pilot lost track of the plane's
position. Other than learning to recognize the plane's
silhouette at different angles and attitudes, the best
insurance is to force yourself to concentrate on each
thing that you do, i.e. making a left turn.  If your mind
strays and you forget what you're doing, coming
back to it can cause a few new grey hairs!

THE HORIZONTAL ROLL. 

Important! Always

remember that, 

when the plane is inverted, the

elevator works backwards.

Therefore, when the

plane is inverted, you give 

down elevator. 

Also, be

sure to fly high enough to give a good margin for
error, as your early attempts will probably end up in
a 30º dive. We also recommend you practice with
the plane in front of you, rather than overhead.
