BME 37% Ultimate Ver 1.0 3/15/2004 Page 3
INTRODUCTION
Congratulations! You have just purchased an outstanding aerobatic aircraft in the form of the BME Aircraft
37% Ultimate Biplane. The Ultimate has long enjoyed a reputation of being one of the best flying RC aerobatic
designs in existence. This reputation was earned and well-proven over the years in what was perhaps the most
prestigious RC event in the world – the Tournament of Champions (TOC). The outstanding flight
characteristics of the Ultimate were recognized and demonstrated in the late 80's and early 90's when it was the
aircraft of choice for almost every TOC competitor and again in 2002 when the Ultimate was flown to 1
st
place
against the best pilots and RC aircraft in the world.
Until now the Ultimate has been readily available only in smaller sizes of 1.20 and below and most recently in
very large versions of 40% scale and above. To fill the large void of 100cc sized aircraft BME has introduced
the 37% Ultimate – just the right size to present well with the 40% monoplanes but a lot easier to handle than
the giants and a the perfect match for the new BME 110 Extreme engine!
