Seagull Models 30% Sukhoi SU-31 "Angry Fish" ARF
The Seagull Models Sukhoi SU-31 "Angry Fish" is a world-class aerobatic powerhouse in a practical 30% scale. With its 89-inch wingspan and iconic "Angry Fish" livery, this aircraft delivers big-airplane presence and rock-solid stability. Perfectly suited for **IMAC precision, F3A-X sequences, and extreme 3D freestyle**, the SU-31 is designed to look, feel, and fly exactly like the full-scale legend.
🦈 The "Angry Fish" Performance Edge
Unlike generic aerobatic ARFs, this Sukhoi features near-square proportions and a long fuselage for exceptional tracking. The carbon-fiber reinforced airframe and fiberglass laminate sections provide the rigidity needed for explosive 3D maneuvers while maintaining a lightweight profile for precision flight.
Key Features
- Carbon-Fiber & Fiberglass Reinforced: Precision-built balsa and plywood airframe reinforced with carbon fiber tubes and black fiberglass laminate for maximum rigidity and impact resistance.
- Quick-Release Wing System: Innovative CNC universal-fastening mechanism ensures secure, tool-free wing attachment for rapid assembly at the field.
- Carbon Fiber Flight Components: Includes high-strength carbon fiber wing tubes, carbon fiber main landing gear, and a carbon-strut reinforced CNC tail gear assembly.
- Pro-Level Hardware Included: Features a 4" aluminum spinner, turnbuckle-style pushrods, ball links, and a full pull-pull rudder system with a dedicated turnbuckle wrench.
- 3D Optimized Control: Large, full-span ailerons provide exceptional roll authority and high-alpha stability for extreme aerobatics.
- Convenient Maintenance: Large, removable canopy hatch offers instant access to radio gear, servos, and the fuel system.
- Scale Finish: Factory-covered in high-visibility “Angry Fish” film with a painted fiberglass cowl, scale 4" PU rubber wheels, and a crystal-clear canopy.
- Complete Fuel System: 750ml transparent tank included with clunk, vent nipples, fuel tubing, and fuel dot.

💡 Gator-RC Modeler’s Tip: Power Management
At this scale, servo current draw can be substantial during high-G maneuvers. We recommend a dual-redundant battery setup (like our Power Unlimited LiFe packs) and a power distribution system to ensure your control surfaces receive steady voltage even under extreme 3D loads.
