Caution: This model is not a toy!
If you are a beginner to this type of powered model, please ask an experienced model flyer for help
and support. If you attempt to operate the model without knowing what you are doing you could easily
injure yourself or somebody else. Please keep your safety and well-being in mind at all times.
Important: before you start construction
Even if you have already built a large number of RC models please read right through these
instructions and check all the kit components against the parts list. We have taken great trouble to
keep construction as simple as possible, without making any compromises in the area of safety.
Check that the radio control system works correctly and at full range before every flight: fit the
transmitter aerial and extend it fully, then switch on the transmitter and the receiving system. Walk
away from the model, and check that all the control surfaces work smoothly and immediately at an
appropriate distance, and deflect in the correct “sense” (direction) relative to the stick movements.
If you are a relative beginner to model flying, we recommend that you enlist the aid of an experienced
model pilot to help you check and test-fly the model.
The RC components and control surface linkages should be installed at specific stages in building the
model, as described in the building instructions. It may be very difficult or even impossible to fit these
parts later.
If you intend to buy a radio control system for this model, ensure that the transmitter and receiving
system components are designed for model aircraft, are approved by your national Post Office
Telecommunications Office, and bear the appropriate serial approval number.
Other radio systems and RF equipment operate on the same frequency bands that we use for radio-
controlled models. It is not possible to be absolutely sure that interference will never be encountered
from such apparatus.
The 35 MHz band is approved for the use of model aircraft, although the regulations regarding
registration and fee payment vary from country to country. In many cases you will need to register your
equipment with your national Telecommunications Office.
If you are not sure of the situation where you wish to fly, please contact your local
Telecommunications Office, or enquire at your local specialist model shop.
