AMA
We urge you to join the AMA (Academy of Model Aeronautics) 
and a local R/C club. The AMA is the governing body of model 
aviation and membership is required to fl y at AMA clubs. 
Though joining the AMA provides many benefi ts, one of the 
primary reasons to join is liability protection. Coverage is not 
limited to fl ying at contests or on the club fi eld. It even applies 
to fl ying at public demonstrations and air shows. Failure to 
comply with the Safety Code (excerpts printed in the back of 
the manual) may endanger insurance coverage. Additionally, 
training programs and instructors are available at AMA club 
sites to help you get started the right way. There are over 
2,500 AMA chartered clubs across the country. Contact the 
AMA at the address or toll-free phone number below.

IMPORTANT!!! Two of the most important things you can do 
to preserve the radio controlled aircraft hobby are to avoid 
fl ying near full-scale aircraft and avoid fl ying near or over 
groups of people.
SAFETY PRECAUTIONS
Failure to follow these safety precautions may result in 
severe injury to yourself and others.
• Keep your face and body as well as all spectators away 
from the plane of rotation of the rotors whenever the battery 
is connected. 
• Keep these items away from the rotors: loose clothing, shirt 
sleeves, ties, scarfs, long hair or loose objects such as 
pencils or screwdrivers that may fall out of shirt or jacket 
pockets into the rotors. 
• The spinning blades of a model helicopter can cause 
serious injury. When choosing a fl ying site for your AXE 
400 3D RTF, stay clear of buildings, trees and power lines. 
AVOID fl ying in or near crowded areas. DO NOT fl y close to 
people, children or pets. Maintain a safe pilot-to-helicopter 
distance while fl ying.
1. Your AXE 400 3D RTF should not be considered a toy, 
but rather a sophisticated, working model that functions very 
much like a full-size helicopter. Because of its performance 
capabilities, the AXE 400 3D RTF, if not assembled and 
operated correctly, could possibly cause injury to yourself or 
spectators and damage to property.
2. You must assemble the model according to the instructions. 
Do not alter or modify the model, as doing so may result in 
an unsafe or unfl yable model. In a few cases the instructions 
may differ slightly from the photos. In those instances the 
written instructions should be considered as correct.
3. You must correctly install all R/C and other components 
so that the model operates correctly on the ground and in 
the air.
