INTRODUCTION
Your new SU-31 Profile Electric ARF is a highly aerobatic airplane. It is capable of all styles of
flying, from gentle and stable slow flight, sport aerobatics, to full out 3D type maneuvers. We hope you
enjoy building and flying your SU-31. 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 SU-31 Profile Electric ARF is transported completely assembled. This 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 aerobatic flying.
The SU-31 Profile Electric ARF is designed for electric motors in the 370-400 size range.
A Himax Outrunner Brushless Motor (HC 2812-1200). is shown in the assembly instructions. The
aircraft was test flown using a Li-polymer 3 cell, 11.1 Volt 1200 to 1320ma battery, and 11 x 4.7 APC-E
propeller and has excellent performance. The final choice of motor and battery is left up to the builder.
A computer radio is recommended to allow the pilot to take full advantage of the capabilities of this
aerobatic aircraft.
Before starting the assembly of your new SU-31 ARF, 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 and follow the order of
assembly before you start building the aircraft. This will help save time and eliminate any chances of
building errors.
