INTRODUCTION
Thank you for purchasing the Great Planes Waco YMF-5
ARF! We offer two options for the builder of this classic model.
Build it as a single seat mail carrier, or as a three seat civilian
open cockpit bipe. You'll enjoy the great scale-like handling
characteristics of this big bipe and the level of detail we've
put into this model. This manual details the installation of
both a glow and gas engine, so please look in the Decisions
You Must Make section for the items required to complete
each type of installation before you begin building.
For the latest technical updates or manual corrections to the
Waco YMF-5 ARF visit the Great Planes web site at www.
greatplanes.com. Open the "Airplanes" link, and then select
the Waco YMF-5 ARF. If there is new technical information or
changes to this model a "tech notice" box will appear in the
upper left corner of the page.

member of the AMA, please join! The AMA is the governing
body of model aviation and membership provides liability
insurance coverage, protects modelers' rights and interests
and is required to fly 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 flying near full-
scale aircraft and avoid flying near or over groups of people.
PROTECT YOUR MODEL, YOURSELF
& OTHERS... FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your Waco YMF-5 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 Waco YMF-5, 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 unflyable 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.
