INTRODUCTION

Pssst! Please don't tell your Super Sportster
90/120 how big it really is, because it thinks it is a
"40-size"! What we mean is that this fantastic
airplane flies with all the smoothness and agility of
our other Super Sportsters (20, 40 and 60), and we
can hardly tell the difference, except for the awe-
some size and power! We think you'll agree that
this is the most exciting Super Sportster yet!
Yes, the Super Sportster 90/120 is a scaled-up
version of our Super Sportster 60, but we have incor-
porated many major structural improvements to add
strength (without extra weight) and to make it much
easier to build straight and true.
In this book we'll take you, one easy step at a
time, through the construction sequence, plus we'll
give you specific pointers on installing your radio,

finishing, balancing and flying your Super Sportster
90/120.
Before starting to build, we encourage you
to read through these introductory pages very
thoroughly, as they contain a lot of vital information
you need to know, such as decisions you must make
now, engine and radio selection, safety precautions
and additional items you will have to purchase.
This is not a beginner's airplane! While the
Super Sportster 90/120 is easy to build and flies
great, we must discourage you from selecting this
kit as your first R/C airplane. It is fast, highly man-
euverable, and lacks the self-recovery characteristics
of a good basic trainer such as the Great Planes
PT Series airplanes. On the other hand, if you have
