- Essential STOL Performance Component — Leading edge slats are critical to the short-take-off-and-landing capability that defines the UMX Timber, helping you achieve slower rotation speeds, shorter takeoff distances and enhanced slow-flight handling that genuine pilots expect.
- Durable Micro-Scale Construction — Built to withstand the rigours of regular flying while maintaining the lightweight properties essential to ultra-micro aircraft performance, these slats combine structural integrity with the minimal weight penalty that micro-scale engineering demands.
- Simple Replacement Process — Designed as a direct bolt-on replacement or upgrade component, these slats integrate quickly with your existing wing, minimising downtime between flights and getting you back to enjoying your UMX Timber without lengthy repair work.
- Maintains Resale Value — Using genuine OEM spares like these E-flite leading edge slats ensures your UMX Timber retains authentic construction and performance credentials, protecting your investment and maintaining the aircraft's desirability on the secondhand RC market.
Technical Performance
The leading edge slats represent a fundamental component of the UMX Timber's aerodynamic architecture, working in concert with the wing design to optimise airflow separation control across the entire flight envelope. These slats are engineered with the precision and attention to detail characteristic of E-flite's approach to ultra-micro aircraft design, where every millimetre of material and every curve of the aerofoil profile contributes to overall performance. The construction materials and profile tolerances are matched to the original specifications, ensuring that when installed, the slats function exactly as E-flite intended, maintaining the aircraft's certified slow-flight characteristics and predictable handling throughout the flight envelope from the gentlest hover approaches to more dynamic manoeuvres. The slats are sized proportionally for ultra-micro scale, keeping the weight contribution minimal whilst delivering measurable aerodynamic benefit. Compatibility with the standard UMX Timber wing assembly is guaranteed, meaning installation requires no modification to existing structure and no adjustment to your transmitter programming or control system setup. For pilots seeking to maintain factory-standard performance or replace damaged components, these E-flite slats are the only choice that delivers authentic engineering credentials and proven aerodynamic effectiveness.

Frequently Asked Questions
- What exactly are leading edge slats and why do I need them on my UMX Timber? — Leading edge slats are aerodynamic devices fitted to the front edge of aircraft wings that help control airflow and maintain lift at very low speeds, which is essential to the STOL (short-take-off-and-landing) performance that defines the UMX Timber. They allow the aircraft to rotate earlier on takeoff, achieve slower landing speeds and maintain stable flight during low-speed manoeuvres that would otherwise cause a conventional aircraft to stall. If your slats are damaged or missing, your UMX Timber will not perform to specification.
- Will these slats fit my UMX Timber? — Yes, these are genuine E-flite OEM components manufactured specifically for the UMX Timber aircraft. They are guaranteed to fit correctly with no modification required to your wing or fuselage.
- Are these difficult to install? — E-flite spare parts are designed for straightforward installation by home builders and maintenance-minded pilots. These slats integrate with the existing wing assembly as a direct replacement or upgrade component. For detailed installation guidance, consult the UMX Timber assembly manual or contact the RC Model Shop team for support.
- How do I know if I need to replace my slats? — If your UMX Timber's slats are visibly cracked, dented, delaminated or missing, replacement will restore factory-standard aerodynamic performance. If you notice the aircraft is not rotating as easily during takeoff or feels sluggish at low speeds compared to a known-good example, worn or damaged slats may be the cause.
- Can I use these slats on other E-flite ultra-micro aircraft? — These slats are engineered specifically for the UMX Timber. Other ultra-micro E-flite models may use different slat profiles or attachment methods. Always check product notes or contact our team to confirm compatibility with your specific aircraft model before ordering.
- What other UMX Timber spares might I need at the same time? — RC Model Shop stocks the complete range of UMX Timber replacement parts including wing assemblies, fuselage sections, tail sets, landing gear, servos, batteries, pushrod sets and more. If you're undertaking a major repair, consider checking whether your control surfaces, motor mount or other components also need attention.
