Great Planes PT-60 Kit - GPMA0119 - Manual (Page 3)

The PT-60 is designed for either 3 or 4 channel
operation By this we mean that you can start with just
rudder, elevator and throttle control, then add a fourth servo
for the ailerons when you want to refine your skills The
ailerons are designed to be locked in the neutral position
after the wing is assembled, but can be activated with only a
few minutes of work and an additional servo We
recommend the three channel setup for beginners Due to
the dihedral (upward angle of the wing) built into the wing
and generous rudder size, the turn and bank response is
almost identical to using ailerons When you are ready to
move up to advanced maneuvers such as crosswind
landings and basic aerobatics, you will need to hook up
the ailerons
If you are already an experienced pilot who is just
looking for a sport model for those lazy summer afternoons,
we provide the necessary information to build the wing with
less dihedral and less washout to allow more responsive
flight characteristics
Due to its rugged construction and light wing loading,
the PT-60 can be powered by a wide range of engines We
flew our prototype with several engines, from a high
performance 61 two-stroke to a 48 four-stroke Every
engine we tried exhibited exceptionally fine performance for
a trainer.
We have written this instruction manual with the novice
in mind and have tried to include enough information,
expert tips and practical suggestions to help get you on the
right track (or should we say runway) from the start Our
goal is for you to experience the fun and satisfaction that
thousands of modelers the world over enjoy, without the
mistakes that have spoiled the hobby for some
Please inspect all parts carefully before starting to
build! If any parts are missing, broken or defective, or if
you have any questions about building or flying this
model, please call us at (217) 398-8970 and we'll be
glad to help. If you are calling for replacement parts,
please look up the part numbers and the kit
identification number (stamped on the end of the
carton) and have them ready when calling.

If this is your first model there are a few necessary supplies
and tools that you should gather before going any further
The single most important item that is required for any
modeling project is a flat work surface No, the kitchen
table is not a good idea This is closely followed by a space
