Master the aerobatic prowess of the E-flite Ultimate 3D 950mm biplane in this RC flight simulation. Pilots command a upgraded airframe with a potent power system that delivers strong 3S output and intense 4S thrust. High-torque metal-geared servos pair with a 60-amp Spektrum Avian Smart ESC for precise control, while the AR637TA receiver provides full-range telemetry on battery voltage, current, temperature, and motor reversing for ground maneuvers.
AS3X technology stabilizes flight across three axes, and optional SAFE Select adds pitch and bank angle limits to avoid upside-down attitudes or steep climbs and dives. Automatic self-leveling holds steady flight when sticks return to center, aiding takeoffs and landings. RC enthusiasts seeking solid 3D aerobatics and simulation racing precision will find their ideal challenge here.
With its unmistakable lines and exhilarating performance, the Ultimate biplane ā in full-scale and in RC model form ā 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-fliteĀ® debuted the Ultimate2 in 2015, earning praise from RC pilots worldwide for its solid aerobatic performance and 3D capabilities. With the Ultimate 3D, E-fliteĀ® 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 Spektrumā¢ Avianā¢ Smart ESC, and the BNFĀ® Basic version is equipped with an AR637TA receiver that offers full-range telemetry including real-time battery voltage, current, temperature and more ā along with motor reversing for special ground handling and other capabilities ā when using compatible transmitters.
This model is equipped with Horizon Hobby and Spektrum exclusive AS3X (Artificial Stabilization ā 3-aXis) and optional-use SAFE (Sensor Assisted Flight Envelope) Select technologies, and when SAFE Select is turned on using the mode switch (B on the Spektrum InterLink DX controller) it offers:
Pitch and Bank Angle Limits
These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.
Automatic Self-Leveling
The airplane instantly returns to and holds level flight when the sticks are released and in the center position. Itās also helpful for keeping the wings level during takeoffs and landings.
