There is risk involved during the operation of this product and the user should take all precautions seriously or serious body injury may occur, it is only suitbale for the person above 14 years old. Improper disassembly, improper adjustments or setup may lead to unsatisfactory or unsafe operation. If you have any questions regarding the use, maintenance, or safe operation of this model, please contact your local retailer. As with any R/C product there are risks involved when flying this model. A beginner should seek the help of a skilled R/C pilot to ensure that the model is airworthy and capable of safe operation. Any damage, neglect, or unfamiliar use of this product can cause unexpected accidents or injury. Please make sure the flying is safe and we are not responsible for any accident. 1. Locate an appropriate place to fly your helicopter: R/C helicopters are capable of flying at high speeds, thus posing a certain degree of potential danger to both the flyer and bystanders, so it is important to choose a right site for flying. First, the space of flying site should be big enough (at least 4*4*4m). Second, the flying site should be open enough, and clear of obstacles. Do not fly your helicopter during the strong counter-flow weather to avoid the unnecessary damage. This RC helicopter, angel 300, have the best performance in terms of control capability and scalability without wind. it may not fly properly outside due to the fluency of airflow so that it is not recommenced to fly outdoor. www.art-tech.com 3 Without wind TIPS FOR SAFETY The help of an experienced pilot will ensure that you will have a well trimmed, correctly functioning helicopter for the first flight. It is strongly advised that you first practice on the simulator prior t o m a k i n g a f l i g h t w i t h y o u r n e w h e l i c o p t e r. 2. Obtain the assistance of an experienced pilot. 3. Always be away from the running parts 4. Keep your helicopter away from humidity. 5. Operate your helicopter gently During the operation of your helicopter the rotor will be spinning at a high rate of speed. Don’t touch any running parts and please keep a proper distance with them. Be conscious of your actions and be careful to keep your hands, face, eyes, and loose clothing away from the blades and gears to avoid being hurt or any damage to the model. Your new Angle 300 helicopter is a hi-tech electronic device, so try to keep the model away from the humidity condition which may result in the operation errors or some other unrespectable faults to the model. Never subject your model to severe weather, such as raining, thunder. The helicopter will give a prompt response to the controlling action,so try to operate the helicopter gently. Try to avoid the excessive operation as this may lead to the helicopter to be out o f control.
