function correctly and safely. You, as operator of the model, must rely upon your own expertise
and judgement in acquiring and operating this model.
Supplementary Safety Notes
Pre-flight checking:
Before every flying session check that all the model's working systems function correctly, and be
sure to carry out a range check.
The first time you fly any new model aircraft we strongly recommend that you enlist the help of
an experienced modeller to help you check the model and offer advice while you are flying. He
should be capable of detecting potential weak points and errors.
Be certain to keep to the recommended CG position and control surface travels. If adjustments
are required, carry them out before operating the model.
Be aware of any instructions and warnings of other manufacturers, whose product(s) you use to
fly this particular aircraft, especially engines and radio equipment.
Please don't ignore our warnings, or those provided by other manufacturers. They refer to things
and processes which, if ignored, could result in permanent damage or fatal injury.
This model aircraft is a high-end product and can create an enormous risk for both pilot and
spectators, if not handled with care, and used according to the instructions. Make sure that you
operate your Yak according to the AMA rules, or those laws and regulations governing the model
flying in the country of use.
The engine, servos and control surfaces have
to be attached properly. Please use only the
recommended engines, servos, propellers,
and accessories supplied in the kit.
Make sure that the 'Centre of Gravity' is locat-
ed in the recommended place. Use the nose
heavy end of the CG range for your first flights,
before you start moving the CG back to a more
critical position for 3D-maneouvers. If you find
that you need to relocate your batteries or
even add weight in the aircraft to move the CG
to the recommended position, please do so
and don't try to save weight or hassle. A tail
heavy plane, in a first flight, can be an enormous danger for you and all spectators. Fix any
weights, and heavy items like batteries, very securely to the plane.
Make sure that the plane is secured properly when you start the engine. Have at least 2 helpers
hold your plane from the tail end, or from behind the wing tips, before you start the engine. Make
sure that all spectators are behind, or far in front, of the aircraft when running up the engine.
Make sure that you range check your R/C system thoroughly before the first flight. It is absolute-
ly necessary to range check your complete R/C installation first WITHOUT the engine running.
