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 molded-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<sup>™</sup> Completion Level Advantage 
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!


Exclusive Technologies 
Exclusive Technologies

This model features 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 and automatic self-leveling that can be turned on and off at the flip of a switch to make this the easiest to fly Twin Otter replica yet!


Telemetry Capable
