Great Planes Sequence 1.20 EP/GP ARF - GPMA1232 - Manual (Page 2)

2
INTRODUCTION
Congratulations and thank you for purchasing the Great Planes
Sequence 1.20 ARF! The Sequence may not have all of the
frills of your exclusive, composite pattern plane, but it’s still
a contender at a fraction of the price. And the Sequence’s
simplicity makes it the perfect entry for beginner/intermediate
pattern pilots or a great practice/backup ship for experienced
pilots. And while we’re at it, the Sequence is a great all-around
sport plane too!
NOTE: An optional wood motor mount for brushless electric
motors is available separately (GPMA4382). This mount allows
outrunners to be “front mounted” and has provisions for geared
inrunners. Full instructions for assembly and mounting are in
the back of the manual on page 28.
For the latest technical updates or manual corrections to
the Sequence 1.20 ARF visit the Great Planes web site at

upper left corner of the page.
