Introduction
De Havilland Canada developed the DHC-6 Twin Otter in 1965. Designed as a rugged STOL (Short Take-Off and Landing) commuter aircraft, the Twin Otter carried passengers and cargo into harsh environments like the sub-zero Antarctic and the scorching North African desert. Viking Air Limited purchased the Type Certificates for all out-of-production de Havilland aircraft in 2005 and announced the Viking Series 400 Twin Otter Production Program two years later. By mid-2015, Viking re-established the Twin Otter as a successful commuter airliner. The E-flite® UMX™ Twin Otter is an ultra-micro class scale replica that can be the perfect first twin-powered model for intermediate to experienced RC pilots. It's convenient and easy to fly, and is outfitted with functional features including LED navigation and landing lights, twin brushless motors with counter-rotating 3-blade props – plus it can be equipped with optional floats to fly from pools, ponds, and lakes!

The Convenient And Easy To Fly Twin!
There's no better choice for RC pilots who want a great first – or next – twin model than the E-flite® UMX™ Twin Otter! It delivers exciting "bush plane" scale looks and performance and the inherent stability of a high-wing design. Because of its convenient ultra-micro size, it can be flown in more places and smaller spaces, including in many yards, parks, and sports fields. You can even remove the landing and install the optional floats (sold separately) to fly from pools, ponds, and lakes! Along with moulded-in panel lines, corrugated control surfaces, and a scale-inspired trim scheme, the UMX Twin Otter is also equipped with scale-looking LED navigation and landing lights and exclusive AS3X® and SAFE® Select technologies. Plus, the brushless motors – with counter-rotating 3-blade props – are compatible with common and affordable 1S 500–800mAh batteries also used for the UMX Ultrix™ and other popular models. The E-flite UMX Twin Otter offers a truly unique flying experience a wide range of pilots can enjoy!
Bind-N-Fly Completion Level AdvantageAlready 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 an off with any switch assigned to that channel (switch A by default on most Spektrum computer transmitters).

What benefits does the 574mm wingspan bring?
The 574mm wingspan offers an ideal balance between in-air stability and compact handling. It ensures the aircraft maintains lift and balance during slow-speed flight while still being small enough for indoor gyms or tight spaces. This size provides responsive aileron control and a natural glide profile during descent.
How do the twin brushless motors improve performance?
The twin 2 x brushless outrunner motors generate balanced thrust across both wings, resulting in enhanced control and scale realism. Twin motors offer better power redundancy and allow for unique flying styles such as differential thrust, adding another dimension of control for experienced hobbyists and new twin-engine pilots alike.
Is the A-EFLU30050 beginner-friendly?
Yes. While it’s a great platform for intermediate users, beginners will also benefit from its stable flight characteristics and predictable control response. The twin brushless setup ensures smooth throttle delivery, and the airframe’s light weight allows for forgiving handling during landings and recovery from turns.
What makes the A-EFLU30050 an ideal choice for indoor flying?
With its compact size and quiet motor configuration, the A-EFLU30050 is designed for indoor flight. The motors run efficiently without excessive noise, and the 574mm wingspan makes it easy to manoeuvre in enclosed areas. It performs well in school halls, gymnasiums and other confined indoor venues.
How does the battery configuration affect the flight?
This model is powered by a 1S3.7V500–800mAhLiPo battery, allowing users to choose between longer flight duration or lighter, more nimble performance. The JST-RCY connector simplifies setup and is compatible with widely available LiPo batteries in the micro RC market.
Is this model suitable for outdoor flight as well?
Yes. In calm weather conditions, the Eflite UMX A-EFLU30050 performs exceptionally outdoors thanks to its stable airframe and twin-motor power. The aircraft remains agile and responsive, with adequate thrust to handle low-altitude cruising, turns and light wind resistance.
For those wanting to explore twin-motor RC flying in a compact and reliable platform, the Eflite UMX A-EFLU30050 offers exciting possibilities. Buy A-EFLU30050 today and enjoy smooth twin-flight control in any environment.
