Supplementary Safety Notes

Pre-flight checking:
Before every 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.
Attention !
This IMAC-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 Extra 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 located 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 absolutely
necessary to range check your complete R/C installation first WITHOUT the engine running. Leave
the transmitter antenna retracted, and check the distance you can walk before 'fail-safe' occurs.
