AJ Aircraft 37" Extra SX — Precision 3D Aerobatic Aircraft
The 37" Extra SX is a true showcase of precision, performance, and innovation, born from the collaboration between AJ Aircraft and legendary aerobatic pilot Andrew Jesky.
Designed for pilots who want to take their 3D flying to the next level, the Extra SX combines a lightweight, responsive airframe with large control surfaces, durable EPP construction, and high-quality hardware. The result is an aircraft that feels remarkably light and floaty in the air while maintaining excellent tracking, smooth handling, and impressive control authority.
Lightweight. Precise. Built for 3D.
The Extra SX has been carefully designed to make advanced aerobatics more accessible while giving experienced pilots plenty of performance to explore.
Its 9 mm EPP foam construction provides an excellent combination of low weight and durability, allowing the aircraft to withstand the demands of regular 3D flying. Carbon-reinforced braces further strengthen the wings, fuselage, and mounting points without compromising the lightweight character that makes this aircraft so enjoyable to fly.
The result is a highly capable platform for practicing and mastering everything from harriers, rolling harriers, waterfalls, knife-edge flight, elevators and torque rolls to more aggressive 3D maneuvers.
The Extra SX's generous control surfaces provide the authority needed for advanced maneuvers, while its predictable handling and excellent tracking make it equally enjoyable for pilots who are still developing their 3D skills.
Designed with Andrew Jesky
Developed together with Andrew Jesky, the Extra SX benefits from a design philosophy focused on precision, control, and practical 3D performance.
The bold color scheme not only gives the aircraft a distinctive presence in the air, but also makes orientation easier during demanding aerobatic sequences.

The Aerobertics Touch
At Aerobertics, we particularly appreciate models that combine serious 3D capability with a forgiving and enjoyable flying character. The 37" Extra SX fits that philosophy perfectly.
It is light enough to float through slow 3D maneuvers, precise enough for demanding aerobatics, and tough enough to handle the inevitable learning moments along the way.
Whether you're working on your first torque rolls or looking to refine your rolling harriers and advanced 3D routines, the Extra SX gives you a solid and confidence-inspiring platform to keep progressing.
Big enough for serious 3D. Light enough to make every maneuver look effortless.
