The full-span ailerons can also be used as flaperons for improved slow flight and STOL performance. Spektrum™ AS3X® and optional-use SAFE® Select technologies are included for easier flying, and the control unit/flight controller provides real-time flight battery voltage telemetry and other data to compatible Spektrum AirWare™ equipped transmitters. Oversized, tundra-style wheels soak up bumps and offer excellent prop clearance. Fly from grass, gravel paths, dirt trails, paved, and other surfaces, outdoors in yards, parks, sports fields and beyond, or indoors in suitable spaces including gymnasiums. Install optional floats (EFLUA1190, sold separately) to add large pools, small ponds, and lakes to your flying site options. Included LED landing, navigation and simulated strobe lights make it possible to fly from earlier to even later in the day. Constructed of advanced EPS material for a lightweight but durable airframe, the UMX Timber X arrives 100% factory-assembled and ready to bind to your 5+ channel DSMX®/DSM2® equipped transmitter. That means you can be flying within minutes of opening the box!
Bind-N-Fly Completion Level Advantage
Already own a SpektrumT 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 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).

Frequently Asked Questions
- Is the E-flite UMX Timber X suitable for beginners or intermediate pilots? — The UMX Timber X is rated as Skill Level 2, making it suitable for intermediate to experienced pilots rather than absolute beginners. However, the optional-use SAFE Select technology provides pitch and bank angle limits plus automatic self-levelling, which can significantly assist newer pilots during their learning curve. If you're new to RC flying, you might consider starting with a more basic model before progressing to the UMX Timber X.
- What battery does the UMX Timber X need and how long does it fly? — The aircraft requires a 3S 11.1V LiPo battery in the 280-350mAh capacity range with a JST-RCY connector. The manual and manufacturer specifications do not provide a specific flight time duration, as this varies significantly depending on your flying style, throttle management, and whether you're performing aggressive 3D manoeuvres or gentle sport flying. Lighter battery choices within the recommended range may provide shorter flight times but better vertical performance, whilst batteries at the heavier end of the range offer longer endurance at the cost of slightly reduced agility.
- Can I fly the UMX Timber X with my existing Spektrum transmitter? — Yes, provided your transmitter is a full-range 5+ channel Spektrum DSMX or DSM2 compatible model. Specifically compatible transmitters include the DXS, DX6e, DX8e, DX6 G2/G3, DX8 G2, DX9, NX6, NX8, NX10, iX12, and iX20. If you own a different Spektrum transmitter not listed, check with the manufacturer to confirm it supports 5+ channels and DSMX or DSM2 protocols before purchasing.
- What makes the UMX Timber X different from other ultra-micro RC aircraft? — The UMX Timber X uniquely combines STOL capability with genuine 3D aerobatic performance in an ultra-micro size. Its shortened-span wing with enlarged chord maintains wing area whilst enabling agile control, full-span ailerons provide maximum authority and optional flaperons for slow-flight optimisation, and the 3S-compatible brushless motor delivers unlimited vertical performance. The inclusion of Spektrum AS3X stabilisation and optional SAFE Select, factory-installed LED lighting, oversized tundra-style tyres, and real-time battery telemetry capability make it exceptionally versatile. The optional float compatibility further expands flying possibilities to water. These combined features deliver a "mild to wild" flying experience unmatched by competing ultra-micro models.
- Can I fly the UMX Timber X indoors? — Yes, the ultra-micro size (570mm wingspan, 137g weight) makes it suitable for flying indoors in gymnasiums and other suitably large enclosed spaces. The oversized control surfaces provide excellent authority even at slow speeds necessary for indoor operations. The factory-installed LED lights also enhance visibility in indoor environments with lower ambient light levels.
- What do the optional floats do and are they included? — Optional UMX floats (model EFLUA1190, sold separately) enable the aircraft to take off and land from water including pools, ponds, and lakes. These floats are not included in the basic package and must be purchased separately if you wish to add water-flying capability to your UMX Timber X.
- Does this model include a transmitter and battery? — No, the Bind-N-Fly Basic package includes only the aircraft with factory-installed motor, servos, and receiver/ESC. You must separately purchase a compatible 5+ channel Spektrum transmitter, a 3S 280-350mAh LiPo battery with JST-RCY connector, and a compatible LiPo charger to complete the setup and begin flying.
- What is Spektrum AS3X and how does it help my flying? — AS3X (Artificial Stabilization–3-aXis) is Spektrum's exclusive stabilisation technology that continuously monitors aircraft attitude across three axes and makes micro-corrections to smooth the effects of wind and turbulence. This technology works automatically in the background without requiring any pilot input, delivering a locked-in, stable feeling that makes the ultra-micro airframe behave like a much larger, expertly-tuned aircraft. This results in smoother, more confident flight in real-world outdoor conditions where wind and thermals are always present.
- What is SAFE Select and can I use it if I'm still learning to fly? — SAFE Select is optional-use flight envelope protection technology that provides pitch and bank angle limits (preventing excessive climb, dive, or roll angles), automatic self-levelling (the aircraft returns to level flight when you centre the sticks), and configurable switch assignment for easy activation. SAFE Select is not enabled by default and can be turned on and off with a transmitter switch, making it ideal for newer pilots or when you want an extra margin of safety without complex programming. For the UMX Timber X, SAFE Select is automatically assigned to channel 5 (Gear), so you can toggle it with any transmitter switch assigned to that channel.
- How durable is the UMX Timber X and what happens if I damage it? — The airframe is constructed from advanced EPS (expanded polystyrene) foam, which is lightweight yet surprisingly durable. EPS is known for its damage tolerance—minor impacts and crashes often result in cosmetic damage rather than structural failure. In the event you suffer damage you cannot repair yourself, E-flite offers a comprehensive range of replacement parts including wings, fuselage sections, control surfaces, and all other airframe components, ensuring your aircraft can be restored to like-new condition.
