With its unmistakable lines and exhilarating performance, the Ultimate biplane — in full-scale and in RC model form — has given pilots everywhere respect for the aerobatic capabilities of an airplane with two wings. Gordon Price built and flew the first 10 Dash "Ultimate" design in the mid 1980s and flew the 10-300 in the 1988 World Aerobatic Championships. E-flite® debuted the Ultimate2 in 2015, earning praise from RC pilots worldwide for its solid aerobatic performance and 3D capabilities. With the Ultimate 3D, E-flite® has updated and upgraded that proven airframe to modern-day standards. Its new power system offers better 3S performance and BALLISTIC power with a 4S battery. Higher-torque and higher-speed metal-geared servos keep you firmly in control with the extra power. It's also equipped with a 60-amp Spektrum™ Avian™ Smart ESC, and the BNF® Basic version is equipped with an AR637TA receiver that offers full-range telemetry including real-time battery voltage, current, temperature and more – along with motor reversing for special ground handling and other capabilities – when using compatible transmitters.
Equipped with the latest modern-day innovations and upgrades, the E-flite® Ultimate 3D biplane raises the bar for scale, sport and precision aerobatic flying — plus all-out 3D performance too! Stronger, faster metal-geared servos and ball-link equipped linkages deliver positive, precise control while the beveled hinge lines make it possible for the control surfaces to deflect to high angles for extreme 3D capabilities. The new power system, with a specially-tuned motor and prop, is compatible with 3S AND with 4S batteries to deliver extra power and unlimited vertical capability — no modifications required. It also features exclusive Smart Technology via the Spektrum™ Avian™ 60-amp Smart ESC, and the BNF® Basic version is equipped with an AR637TA receiver that offers full-range telemetry including real-time battery voltage, current, temperature and more to compatible transmitters. Plus, with 7+ channel transmitters, the optional-use motor reversing function adds special ground handling and other unique capabilities. The composite-reinforced, hollow-core EPO construction provides a lightweight but durable airframe that's factory-finished in a striking, ready-to-admire trim scheme. Best of all you can have the Ultimate 3D flight-ready in less time than it takes to charge a battery because no glue is required for final assembly, and installation/removal of the wings is tool-free for easy storage and transport. This makes it the easiest and best choice for almost any pilot looking for their first or next biplane!

Beveled hinge lines make it possible to deflect every control surface to high angles for outstanding control and extreme 3D aerobatic capability. Vortex generators also enhance the performance and handling overall so you can fly as mild or as wild as you'd like — whether you prefer scale, sport, precision aerobatic or all-out 3D flying.
The factory-installed brushless power system features a 60-amp Spektrum™ Avian™ Smart ESC plus a specially-tuned motor and prop that deliver an abundance of thrust with a 3S LiPo battery, or extra power and unlimited vertical performance with a 4S battery without the need for any modifications or upgrades.
Composite-reinforced, hollow-core construction with EPO material delivers a lightweight yet durable airframe. The Ultimate 3D is also equipped with higher-torque, higher-speed, metal-geared servos and ball-link equipped linkages for added durability plus more positive and precise control.
No glue is required for final assembly, and you can have the Ultimate 3D ready to fly in less time than it takes to charge a battery. Although it's conveniently sized to fit fully assembled in just about any vehicle, installation and removal of the wings is tool-free for easy storage and transport. Pins easily secure the struts and thumbscrews secure the wings to the fuselage.
The Ultimate 3D is equipped with an exclusive Spektrum™ Avian™ Smart ESC that can provide a variety of real-time power system related telemetry data including motor RPM, current, battery voltage and more via compatible receivers (including the AR637TA) and Spektrum AirWare™ equipped transmitters (including the DX6e and 8e, DX6 G2/3 and 8 G2, the DX9, iX12, iX20 and others) while you fly. It also features optional-use motor reversing to offer special ground handling and other capabilities (7+ channel transmitter required for reversing).
Already own a Spektrum™ transmitter? Bind-N-Fly® (BNF®) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!
The Ultimate 3D is equipped with exclusive Spektrum™ AS3X® and SAFE® Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you're flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-leveling that can be turned on and off at the flip of a switch! And if you don't want to enable the SAFE Select features, simply bind the receiver normally and only AS3X will be active.
