Bind-N-Fly Completion Level Advantage
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!
This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX® receiver featuring AS3X® (Artificial Stabilization-3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence so you enjoy a sense of stability and precision that makes it feel like you're flying a much larger, expertly tuned aircraft.
If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No programming is required.
With SAFE Select enabled, you get:
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 centre position. It's also helpful for keeping the wings level during takeoffs/launches and landings.
Easy Switch Assignment-No Complex Programming Required
- The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn't require any complex programming and takes just a few seconds. For UMX models like this one, SAFE Select is automatically assigned to channel 5 (Gear) so you can turn it on and off with any switch assigned to that channel (switch A by default on most Spektrum computer transmitters).

Frequently Asked Questions
- Is the E-flite SR-71 Blackbird suitable for beginner RC pilots? — No, this model is specifically designed for experienced RC pilots with Skill Level 4 designation. The SR-71 requires solid understanding of EDF jet operations, throttle management, and aerodynamic principles. Whilst the AS3X and SAFE Select systems make it more forgiving than traditional EDF jets, it is not recommended for those new to RC flying. If you're starting out, consider beginning with a dedicated trainer aircraft before progressing to high-performance jets like this Blackbird.
- What battery does the SR-71 Blackbird Twin 40mm EDF require? — This model requires a 4S 14.8V 2200mAh 30+C LiPo battery with either an EC3™ or IC3® connector. The "4S" designation means four lithium polymer cells in series, delivering 14.8 volts nominal output. The 2200mAh capacity provides adequate flight time for extended sessions, whilst the 30+C discharge rating ensures the battery can safely deliver the current demanded by the twin brushless motors and dual ESCs during aggressive flying. Always purchase your battery from an authorised RC retailer and follow proper storage and charging procedures.
- What transmitter do I need to fly the SR-71 Blackbird? — You will need a full-range 5+ channel Spektrum DSMX or DSM2 compatible transmitter. The aircraft's control unit includes a receiver that binds directly to any Spektrum-brand radio system or third-party transmitters that support DSMX/DSM2 protocols. The five-channel requirement ensures you have adequate control inputs for throttle, aileron, elevator, rudder and landing gear (if equipped). Popular compatible options include the Spektrum DX5, DX6 and DX7 transmitter systems.
- Can I use the SR-71 Blackbird for aerobatic flying? — Yes, the SR-71 Blackbird is fully aerobatic-capable when the optional SAFE Select flight envelope protection is disabled. With AS3X stabilisation engaged, the aircraft will maintain smooth, coordinated flight through loops, rolls, inverted flight and other aerobatic manoeuvres. However, SAFE Select will prevent extreme pitch attitudes and stalls, limiting aerobatic potential when activated. Experienced pilots can toggle SAFE Select off via their transmitter to unlock full aerobatic capability.
- What is the difference between this BNF Basic model and other SR-71 variants? — The BNF (Bind-and-Fly) Basic configuration arrives almost completely assembled with all electronics pre-installed and tested, requiring only a transmitter and battery to fly. This differs from PNP (Plug-and-Play) versions that require the pilot to install a receiver and ESCs, and from RTF (Ready-to-Fly) variants that include a transmitter in the box. The Basic designation indicates this model includes the essential Spektrum control system without additional optional components, keeping the price accessible whilst maintaining full performance capability.
- Does the SR-71 Blackbird include landing gear? — Landing gear is available as an optional addition and is not included in the box. The model can be flown without landing gear for maximum manoeuvrability and weight reduction, or you can add fixed gear with a steerable nose wheel for conventional takeoffs and landings on smooth surfaces such as runways. Check with your RC Model Shop supplier regarding landing gear availability as a separate purchase.
- What flight time can I expect from this model? — Typical flight durations with a fully-charged 4S 2200mAh LiPo battery range from 8 to 12 minutes depending on flying style, throttle management, and wind conditions. More aggressive aerobatic flying will consume battery capacity faster, whilst steady cruise flight and altitude climbs will extend flight time. Always land with reserve battery capacity remaining to protect your LiPo battery's lifespan and safety.
- Is this model waterproof or weather-resistant? — The SR-71 Blackbird is not specifically designed for waterproof operation. Whilst foam airframes are inherently resistant to minor moisture exposure, the pre-installed electronics and servos should be protected from rain and water ingress. Always store the aircraft in a dry location and avoid flying in wet conditions to maintain reliability and component longevity.
