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.

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 fly at AMA clubs.

Though joining the AMA provides many benefits, one of the 

primary reasons to join is liability protection. 

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:

Academy of Model Aeronautics

5161 East Memorial Drive • Muncie, IN 47302

Phone (800) 435-9262 • www.modelaircraft.org

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.

require a bit of decision making ahead of time. There isn’t a right or 

a wrong choice, so choose the items that work best for you.

motor, 40 amp ESC (minimum), and 4s 2400mAh lipo.

Here is a list of additional parts needed to complete and fly this 

kit, all of which must be purchased separately. Again, we would
