Adjust the wing and fuselage configuration as shown in the diagrams.

The ideal C. G. position is 135 mm (5.3 in) behind the leading edge
measured at where the wing meets the fuselage. In order to obtain
the C. G. specified, add weight to the fuselage or move the battery
position. Check the C. G. before flying.

Important Safety Precautions
First time flyer should never fly by himself / herself. Assistance from experienced flyer is
absolutely necessary.
Pre - flight adjustment must be done before flying, it is very dangerous to fly a badly
adjusted aircraft.
pre -
Make sure the air field is spacious, never fly the plane too close to people and never get
too close to a running propeller.
If you find wrinkles on the covering as a result of weather changes, you can use hot iron
to remove the wrinkles. Please begin with lower temperature setting and gradually raise
the temperature until the wrinkles are gone. Too hot an iron may damage the covering.
Check and re-tighten up all factory assembled screws, use thread locker if necessary.
AT-6 TEXAN is specially designed to be powered by 0.91-1.10 4-stroke glow engine, using a
more powerful engine does not mean better performance. In fact, over powered engine may
cause severe damage and injuries.
When Flaps are lowered, nose of model will rise. The nose-up varies with the speed at which
the models is flying when you lower the flaps and the extent to which they are lowered. Check
effect of flaps at higher altitude to avoid surprises during landing. You may apply down trim
of the elevator to compensate for the nose-up effect when lowering the flaps. Taking off with
flaps lowered is not recommended, as the increased drag may require a longer runway and
more engine power for the model to take off.
P.13
Should you require to bend the landing gear wire, please insert a round metal bar into the
spring ring and apply force there as leverage. Bending the wire directly may damage the
mounting block structure.
Warning!
,
Don t use hot iron near the seams or edges,hot iron will melt the glue and shrink
the covering at the sa me time,causing the seams to pull away.

Usage of the transparent 3D template
This transparent 3D template
is used for position guidance
of the actual cutting of the
pre-painted cowling.
Simply cut the transparent 3D template to fit your engine and
exhaust pipe, then slide onto the actual cowling and use as
template to mark the openings required for final cutting.
