Make sure that all passers-by and onlookers are aware of the hazards involved in the operation
of your model. Remind spectators to keep a safe distance from the model.
Always maintain a safe distance between your model and other people or objects. Never fly low
over people or directly towards them.
Radio-controlled models should only be flown in a temperature range of -5° to +35°C. More
extreme temperatures can lead to changes in battery capacity, material characteristics, the
strength of glued joints and other unwanted effects.
All model flyers should behave in a way which minimises the danger to people and property.
Never act in any manner which will disturb other pilots, or have an adverse effect on safe,
orderly flying at the site.
Don’t operate your model aeroplane in the vicinity of overhead power cables, industrial sites,
residential areas, public roads, school playgrounds or sports fields etc.
Pre-flight checks
Check that the radio control system works correctly and at full range before every flight: switch
on the transmitter and receiving system, and ensure that all the control surfaces work
smoothly, and deflect in the correct “sense” in relation to the stick movements.
If you are a beginner to this type of model flying, we recommend that you enlist an experienced
model pilot to help you check and test-fly the model.
Please don’t ignore our warnings. They refer to hazardous materials and processes which, if
ignored, can result in fatal injury or serious damage to property.
Propellers powered by a motor constitute a permanent hazard and represent a real risk of
injury. Don’t touch them with any part of your body. For example, a propeller spinning at high
speed can easily cut your finger badly.
Keep well clear of the rotational plane of the propeller or rotor. You never know when some
part may come loose and fly off at high speed, hitting you or anybody else in the vicinity. In
unfavourable circumstances this could result in serious injury. Ensure that the revolving
propeller never comes into contact with any object.
Make sure that it is impossible for any object to stall or block the propeller.
Every time you intend to operate your model, check carefully that it and everything attached to
it (e.g. propeller, tailplane etc.) is in good condition and undamaged. If you find a fault, do not
fly the model until you have corrected it.
Radio interference caused by unknown sources can occur at any time without warning. If this
should happen, your model will be uncontrollable and completely unpredictable. Never leave
your radio control system unguarded, as other people might pick it up and try to use it.
Do not switch the electric motor on unless you have checked that there is nothing in the
rotational plane of the propeller. Never attempt to stop the propeller when it is spinning.
Electric motors with propellers fitted must only be run when firmly mounted.
If you are to fly your model safely and avoid problems, it is essential that you are aware of its
position and attitude throughout each flight -
so don’t let it fly too far away. If you detect a
control problem or interference during a flight, immediately land the model to prevent a
potential accident. Model aeroplanes must always give way to full-size aircraft. Take-off and
landing strips should be kept free of people and other obstacles.
Your HoTT COMPUTER RC system can only work reliably if the batteries are kept fully charged.
Never use hot, faulty or damaged batteries. It is important to observe the instructions supplied
by the battery manufacturer.
Please don’t misunderstand the purpose of these notes. We only want to make you aware of
the many dangers and hazards which can arise if you lack knowledge and experience, or work
carelessly or irresponsibly. Provided that you take reasonable care, model flying is a highly
creative, instructive, enjoyable and relaxing pastime.
