SCALE COMPETITION
The scale of this model is 1/9
th
(or 11%). These
fi gures were derived from comparing the wing span
and fuselage length of this model to the wingspan and
fuselage length of the full-size. Though the Top Flite
B-25J Mitchell is an ARF and may not have the same
level of detail as an “all-out” scratch-built competition
model, it is a scale model nonetheless and is therefore
eligible to compete in the Fun Scale class in AMA
competition (we receive many favorable reports of
our ARFs in scale competition!). In Fun Scale, the
“builder of the model” rule does not apply. To receive
the fi ve points for scale documentation, the only proof
required that a full size aircraft of this type in this paint/
markings scheme did exist is a single sheet such as a
kit box cover from a plastic model, a photo, or a profi le
painting, etc. If a black-and-white photo is used, other
written documentation of color must be provided.
Contact the AMA for a rule book with full details. See
below for the AMA contact information.
If you would like photos of the full-size B-25J for
scale documentation, or if you would like to study the
photos to add more scale details, photo packs are
available from:

aviation and membership provides liability insurance
coverage, protects modelers’ rights and interests and
is required to fl y at most R/C sites.

IMPORTANT!!! Two of the most important things you
can do to preserve the radio controlled aircraft hobby
are to avoid fl ying near full-scale aircraft and avoid
fl ying near or over groups of people.
IMAA
The Top Flite B-25 ARF qualifi es as a “giant-scale” model
and is therefore eligible to fl y in IMAA (International
Miniature Aircraft Association) events. The IMAA is an
organization that promotes non-competitive fl ying of
giant-scale model aircraft. If you plan on attending an
IMAA event refer to the IMAA Safety Code at www.
fl y-imaa.org under the “Sanctions” heading in their
site index. IMAA contact information is also available
in Model Aviation, the monthly newsletter magazine
from the AMA. The IMAA can also be contacted at the

PROTECT YOUR MODEL, YOURSELF AND
OTHERS. FOLLOW THESE IMPORTANT
SAFETY PRECAUTIONS
1. Your Top Flite B-25J Mitchell ARF should not be
considered a toy, but rather a sophisticated, working
model that functions very much like a full-size
airplane. Because of its performance capabilities, the
B-25 ARF, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators
and damage to property.
2. You must assemble the model according to the
instructions. Do not alter or modify the model, as
doing so may result in an unsafe or unfl yable model.
In a few cases the instructions may differ slightly from
the photos. In those instances the written instructions
should be considered as correct.
3. You must take time to build straight, true
and strong.
4. You must use an R/C radio system that is in good
condition and correctly sized engine and components
as specifi ed in this instruction manual. All components
must be correctly installed so that the model operates
correctly on the ground and in the air. You must check
the operation of the model and all components before
every fl ight.
5. If you are not an experienced pilot or have not
fl own this type of model before, we recommend that
you get the assistance of an experienced pilot in your
R/C club for your fi rst fl ights. If you’re not a member
of a club, your local hobby shop has information
about clubs in your area whose membership includes
experienced pilots.
6. While this kit has been fl ight tested to exceed
normal use, if the plane will be used for extremely
high stress fl ying, or if engines larger than ones in
the recommended range are used, the modeler is
responsible for taking steps to reinforce the high
stress points and/or substituting hardware more
suitable for the increased stress.
