NOTICE E325 PVC
1. R/C models are not toys. This product is a high-precision flying machine.Possibilities
of unexpected crashes may occur due to electronic interference, incorrect operation,
or poor mechanical maintenance. Although it is a small-sized helicopter, the rotor
blades rotate at high speeds, which may cause serious damage, injury, or death if
the model hits people or property. Therefore, extreme caution must be exercised 1.
during operation.
2. Thunder Tiger ensures parts packaged in this product is of the highest quality.However,
after assembly and usage, parts damaged due to wear or misuse will not be replaced
under any circumstances. If you have any questions regarding its operation and 2.
repair, Thunder Tigers service agents are able to provide free technical guidance.
3. This product is only recommended for users ages 16 and up. Because flying a R/C
helicopter is difficult, beginners must receive guidance and supervision from experienced
3.
pilots to minimize unexpected danger. Practice in spacious areas, far away from
obstacles such as buildings, trees, electrical towers, or crowds.
4. To decrease the cost of repair and maintenance for beginners, it is recommended
4.
to fly the helicopter with a practice rack and to learn basic flying skills with a computer
R/C flying simulator. (Crashes in simulators are free to repair!)
Operating a model helicopter requires a high degree of responsibility and skill. If
you are a newcomer to the hobby, it is best to seek help and guidance from accomplished
model helicopter pilots. This will greatly speed up the learning process and have you
flying successfully in a reasonable amount of time. We also would strongly urge you
to join the Academy of Model Aeronautics. The AMA is a non-profit organization that
provides its members with a liability insurance plan as well as monthly magazine entitled
Model Aviation. All AMA charter aircraft clubs require all pilots to hold a current AMA
sporting license prior to operation of their models at club fields.
