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 the 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-manoeuvres. 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 up 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. Then start up the engine, run it at about half throttle and
repeat this range check with the engine running. Make sure that there is no range
reduction before 'fail-safe' occurs. Only then make the 1st flight. If you feel that the range
with engine running is less then with the engine off, please contact the radio supplier and
the engine manufacturer and DON'T FLY at that time.
