Construction Manual

WARNING

READ THROUGH THIS MANUAL 

BEFORE STARTING CONSTRUCTION. 

IT CONTAINS IMPORTANT WARNINGS 

AND INSTRUCTIONS CONCERNING 

THE CONSTRUCTION AND USE OF THIS 

MODEL.

A Radio-Controlled aircraft is not a toy!

If misused, it can cause serious bodily harm 

and damage to property. Fly only in open 

areas, preferably at AMA (Academy of Model 

Aeronautics) approved flying sites, following all 

instructions included with your radio, powerplant, 

electronics and batteries.

• Inspect your model before every flight to ensure it is airworthy.

• Be aware of any other radio frequency user who may present an 

interference problem.

• Always be courteous and respectful of other users in your 

selected flight area.

• Choose an area clear of obstacles and large enough to safely 

accommodate your flying activity.

• Make sure this area is clear of friends and spectators prior to 

launching your aircraft.

• Be aware of other activities in the vicinity of your flight path that 

could cause potential conflict.

• Carefully plan your flight path prior to launch.

• Abide by any and all established AMA National Model Aircraft 

Safety Codes.

IMPORTANT!!! 

Two of the most important things you can 

do to preserve the radio controlled aircraft hobby are to avoid flying 

near full-scale aircraft and avoid flying near or over groups of people. 

WARNING: This product can expose you to chemicals including lead, which 

is known to the State of California to cause cancer and birth defects or other 

reproductive harm.  For more information go to www.P65Warnings.ca.gov.
