INTRODUCTION 

 
Your new Stingray

 

Electric ARF is a highly maneuverable electric powered sport airplane.   It is 

capable of gentle and stable slow flight to full out pattern flying. We hope you enjoy building and flying 
your Stingray.   This aircraft builds easily, quickly, and accurately due to the CAD design and LASER 
cutting technology.  The wing, stab and fuse are pre-assembled and covered requiring only a minimum 
amount of gluing or drilling.  

 
The Stingray

 

Electric ARF can be transported completely assembled.  This totally eliminates 

assembly time when you get to the flying field.  The battery installs easily with Velcro to get you into the 
air quickly to enjoy high performance pattern flying.  

 

HIMAX 2820 

motor is shown in the assembly instructions.  The aircraft was tested with this 

motor, a Kokam 3 cell 11.1v 2000 HP LiPoly battery, and a

 Hacker X-30 

speed control.  These 

components provided excellent performance.  The final choice of motor, battery, and speed control is left 
up to the builder.   A minimum four channels in the radio are required to allow the pilot to take full 
advantage of the capabilities of this aerobatic aircraft.  

 
Before starting the assembly of your new Stingray, please inventory and inspect all parts and 

hardware for imperfections or damage.  Notify AEROWORKS 

IMMEDIATELY

 if there are missing or 

damaged parts.   

 

IMPORTANT!

     

Please read through the assembly manual carefully before starting assembly.  

Follow the order of assembly in the manual. This will help save time and eliminate any chances of 
building errors. 

 

INTENDED USE 

 
This plane should not be regarded as a toy. This is a high performance plane and is recommended for 
pilots who are beyond the trainer-stage and are comfortable with flying a high performance sport plane.
