The Next Generation of Aerobatic Perfection

The Extreme Flight 91" Extra NG represents the cutting edge of modern RC aerobatic aircraft design. Inspired by Walter Extra’s stunning full-scale Extra NG, this model captures the same futuristic lines and flight refinement, bringing true next-generation performance to the 70–76cc class.

Developed using the latest aerodynamic package from the 104" NG and enhanced with composite construction techniques, the 91" NG delivers the perfect blend of strength, lightness, and agility. Its Gen 2 quick-release wing and canopy latch system ensures the fastest field setup possible, while pre-hinged and sealed control surfaces guarantee crisp, predictable handling.

Available in two striking Ultracote colour schemes, the Extra NG is as elegant on the ground as it is in the air. With legendary Extreme Flight precision and durability, this aircraft is designed for pilots who demand the absolute best in 3D, XA, and precision aerobatics.
