Introduction
The A-10 Thunderbolt II, affectionately called the "Warthog" due to its aggressive look and unique Close Air Support (CAS) capabilities, is one of the most iconic U.S. Air Force aircraft of all time - valued highly for its excellent maneuverability at low speeds and altitude, and for being an accurate and survivable weapons-delivery platform. With its affordable and practical ultra micro size, the updated and upgraded E-flite® UMX™ A-10 Twin 30mm EDF (Electric Ducted Fan) jet now enables more RC pilots to fly an exciting "Hog" replica in more places!

Overview
The E-flite® UMX™ A-10 Thunderbolt II Twin 30mm EDF ultra micro jet is the most practical and easiest to fly A-10 RC model yet! New upgrades make this replica of the iconic U.S. Air Force aircraft easier for a wider variety of experienced pilots to enjoy - including those with limited EDF experience. The BNF® Basic model's industry-leading Spektrum™ 2.4GHz technology binds to your 5+ channel DSMX®/DSM2® transmitter for full 4-channel control, plus the benefits of exclusive AS3X® and optional-use SAFE® Select technologies. It's 100% factory-assembled and ready to deliver an authentic A-10 jet flying experience almost immediately. The fully-moulded airframe features a factory-applied "desert camo" trim scheme and is strengthened with a carbon fiber reinforced fuselage and nose. Factory-installed twin brushless power systems feature more powerful 2S and 3S-compatible outrunner motors with larger diameter 30mm fans, for improved vertical performance and speed compared to other models in its class - plus longer-than-average EDF flight times when using the recommended 450-850mAh LiPo batteries. Use the included fixed landing gear with steerable nose wheel to taxi, take off and land on paved, packed dirt or grass surfaces at large parks and fields. Or leave the landing gear off for more speed and vertical performance plus easy over hand launches and landings on grass. With the A-10 Thunderbolt II Twin 30mm EDF, you can start flying your first mission within minutes!
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 familiarising 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 center 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 an off with any switch assigned to that channel (switch A by default on most Spektrum computer transmitters).

What makes the 562mm wingspan ideal for high-speed micro jets?
The 562mm wingspan provides a stable lift-to-thrust ratio while remaining compact enough for tight control surfaces and sharp directional changes. This size gives the aircraft the glide and stability needed for longer passes while retaining its micro-scale agility in confined spaces or parks.
How does the 8800Kv motor transform the flying experience?
The high-revving 8800Kv brushless outrunner motor delivers rapid throttle response and fast acceleration, allowing the pilot to perform dynamic manoeuvres and vertical climbs with ease. This motor is specifically designed to operate with high-discharge 3S LiPo packs, producing fast jet-like speed without needing ducted fan systems.
Why is a 3S850mAh battery ideal for this aircraft?
The 3S850mAh configuration provides optimal voltage and capacity for the brushless motor and airframe. It enables consistent power delivery during demanding aerobatics, while still keeping weight in check for balanced flight characteristics. This battery setup ensures longer flight times and better overall handling compared to smaller 2S systems.
Is the A-EFLU6550 suitable for newer pilots?
This aircraft is best suited for intermediate to experienced flyers who have already mastered basic throttle and directional control. Its speed and agility make it exciting but demanding, so it's ideal for those progressing from smaller prop aircraft or slower micro jets.
What environments can this UMX jet handle?
The A-EFLU6550 is perfect for open outdoor spaces such as parks or club flying fields. Its lightweight frame and powerful motor allow it to cut through mild wind conditions, while its compact size keeps it nimble and easy to recover from aggressive manoeuvres. It can also be flown in larger indoor arenas when weather or space permits.
Designed for performance, portability and speed, the Eflite A-EFLU6550 gives jet fans a chance to fly fast and light. Buy A-EFLU6550 today and experience compact EDF-style thrills in your own flying space.
