Great Planes T-Craft 20 Kit - GPMA0155 - Manual (Page 3)

Since its introduction in the late 1930's, there have been 100's
if not 1000's of the full size T-Craft sold in the U.S.A. They have
come in many versions. Some are very stable, while others
are very aerobatic, like the clipped wing T-Craft. Great Planes
has taken the aerobatic qualities of the full size Clipped Wing
T-Craft and designed them into this .20 sized scale model.
This plane loops, rolls and flies knife edge but still has the
stability of a high wing airplane. So if you’re ready for an easy
building, fun to fly airplane, let's finish reading this introduction
and start building.
While the T-Craft 20 is easy to fly, it does not have the total
self-recovery and stability of a basic trainer like the Great
Planes series of PT
™ basic trainers. Therefore, if you have
never flown an R/C airplane before, we strongly recommend
that you seek out the assistance of an experienced R/C pilot
who will be able to check out your construction and help you
with your first flights. On the other hand, if you have already
learned the basics of R/C flying, and you are able to safely
handle a low wing airplane, the T-Craft 20 is an excellent
choice to improve your flying skills.
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
airplane, please give us a call at (217) 398-8970 or e-mail
us at [email protected] and we'll be
glad to help. If you are calling for replacement parts,
please reference the part numbers and have them ready
when calling.
1. Build the plane according to the plans and 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 plans
and written instructions should be considered as correct.
2. Take time to build straight, true and strong.
3. Use an R/C radio system that is in first-class condition. We
highly recommend the use of micro servos on the ailerons
and standard servos on the rudder, elevator and throttle.
4. You must properly install all R/C and other components so
that the model operates properly on the ground and in the air.
5. You must test the operation of the model before every
flight to insure that all equipment is operating, and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show signs of wear or fatigue.
Remember: Take your time and follow the directions to
end up with a well-built model that is straight and true.
