Fly only in open areas to ensure safety. It is recommended

flying be done at AMA (Academy of Model Aeronautics)

approved flying sites. Consult local ordinances before

Keep loose items that can get entangled in the propeller

away from the prop, including loose clothing or other objects

such as pencils and screwdrivers. Especially keep your

hands away from the propeller as injury can occur.

BATTERIES

Notes on Lithium Polymer Batteries

When used improperly, lithium polymer batteries are

significantly more volatile than alkaline or Ni-Cd/Ni-MH

batteries used in RC applications. Always follow the

manufacturer’s instructions when using and disposing of any

batteries. Mishandling of Li-Po batteries can result in fire

causing serious injury and damage.
