Great Planes ESP6 Easy Sport 60 - GPMA0152 - Manual (Page 4)

Both the Easy Sport 40 and 60 are built from this
manual. Nearly all the parts in the Easy Sport series
are identical, so most of the differences are only in the
size and thicknesses of the pieces - you can't even
tell from most of the photos When important
differences do arise between the 40 and 60, they are
clearly indicated so you'll have all the information you
need to build your model.

The recommended engine size range is as follows:
Easy Sport 40 Easy Sport 60
40 to 50 cu in 2-stroke .60 to 90 cu in 2-stroke
.60 to .80 cu. in. 4-stroke .70 to 1.20 cu. in 4-stroke
The Easy Sport 40 will f l y well with any of the
recommended engine sizes For "Hot Dogging" and
speedy performance we suggest either an 0 S 46FX or
a SuperTigre" GS-45, both 2-stroke engines An O.S.
FS-70 Surpass is a good choice for those who prefer
4-stroke engines
For the Easy Sport 60, an O.S. 61 SF or a SuperTigre
S-61K will have you burning holes in the sky with power
to spare If a 4-stroke engine is what you desire, the
O.S. FS-91 is the perfect choice
The Great Planes Easy Sport can be set up with
tricycle gear (nose wheel) or built to be a taildragger
Many pilots prefer taildraggers as they are more sporty
looking and offer less drag than the traditional landing
gear configuration But they can present minor ground
handling problems Tricycle gear, on the other hand,
provides stable tracking during takeoff and landing, but is
heavier and creates more drag than a tail wheel.
If you choose to build your Easy Sport 40 as a
taildragger, you will need to purchase a wire tail gear
assembly (GPMQ1900), a 1" tail wheel (GPMQ4241) and
two 3/32" wheel collars (GPMQ4302) For the Easy Sport
60 you will need to purchase a wire tail gear assembly
(GPMQ1900), a 1-1/2" tail wheel(GPMQ4243) and two
3/32" wheel collars (GPMQ4302).
