- Integrated BEC — The built-in Battery Elimination Circuit eliminates the need for a separate receiver battery pack, allowing you to power your receiver and servos directly from your main LiPo battery, which simplifies wiring and reduces overall weight in your RC aircraft.
- EC3 Battery Connector — The standard EC3 battery connector ensures secure, reliable power connections that are quick to disconnect and reconnect, making it easy to swap batteries between flights or perform maintenance on your RC plane.
- Genuine E-flite Component — As an authorised E-flite product, this ESC is manufactured to exacting quality standards and is fully compatible with the complete range of E-flite brushless motor systems, giving you confidence in its reliability and longevity.
- Extensive Aircraft Compatibility — This ESC is compatible with a comprehensive list of E-flite aircraft models including the EFL3350, EFL3375, EFL3550, EFL3575, EFL5350, EFL5375, EFL8250, EFL8350, EFL8450, EFL8475, EFL8550, EFL8650, EFL8950, EFL8975, EFL9150, and EFL9175, making it a versatile upgrade option for E-flite owners across the UK.
Technical Performance
The E-flite 40 AMP Brushless ESC is engineered with precision electronic circuitry to deliver smooth, responsive power delivery to brushless motors across the full range of E-flite aircraft systems. At 40 amps continuous current capability, this ESC strikes an excellent balance between performance and thermal management, allowing you to fly with confidence without worry of voltage sag or power loss during sustained manoeuvres. The integrated BEC eliminates the complexity of powering your receiver and servos from a separate battery, streamlining your aircraft's electrical architecture and freeing up valuable weight that can be allocated to fuel capacity, payload, or improved flight performance. The EC3 battery connector provides a gold-plated, low-resistance connection point that minimises voltage drop and ensures maximum efficiency from your battery pack. This ESC has been validated across dozens of E-flite aircraft models and motor combinations, proving its reliability in real-world flying conditions. Whether you're operating a nimble aerobatic aircraft, a scale warbird, or a transport category model, the 40-amp rating ensures your ESC will handle the electrical demands without throttling or failsafe intervention, giving you the smooth, predictable control response that defines a quality brushless flight experience.

Frequently Asked Questions
- Is the E-flite 40 AMP Brushless ESC compatible with my E-flite aircraft? — This ESC is compatible with a extensive list of E-flite models including the P-51D Mustang 1.2m, T-34 Mentor, Aeronica Champ, Stearman PT-17, AT-6 Texan, PA-20 Pacer, T-28 1.2m, F4U Corsair 1.2m, Spitfire Mk XIV 1.2m, Radian XL 2.6m, Sukhoi SU-29MM Gen2, P-47 Thunderbolt 1.2m, PT-17 1.1m, F-27 Evolution, Maule M-7 1.5m, Pitts S-1S models, P-39 Airacobra 1.2m, EC-15000 Twin 1.5m Cargo, and RV-7 1.1m. If you have an E-flite aircraft model, check the compatibility list provided; if your specific model isn't listed, contact our team for confirmation before ordering.
- What battery type does this ESC require? — The E-flite 40 AMP Brushless ESC is designed to work with LiPo (Lithium Polymer) battery packs. The integrated BEC will power your receiver and servos, so you only need one main battery pack to fly. Battery voltage and capacity requirements depend on your specific aircraft and motor combination, so always consult your aircraft manual for the recommended battery specifications.
- Can I use this ESC with a 4S LiPo battery? — Based on real customer enquiries, the recommendation is typically 3S LiPo maximum for this 40-amp ESC. For higher cell count setups like 4S, users are advised to upgrade to a 60-amp ESC or higher to ensure adequate headroom and reliability. Always check your aircraft manual for the recommended ESC amperage rating.
- What is the difference between this 40-amp ESC and other E-flite ESC options? — E-flite manufactures ESCs in various current ratings including 30-amp and 60-amp units. The 40-amp rating of this model makes it suitable for mid-range brushless motor systems, while 30-amp ESCs are intended for smaller aircraft and 60-amp units for larger or more powerful systems. The 40-amp rating provides an excellent middle ground for many popular E-flite aircraft models.
- Will this ESC work with any RC receiver? — Yes, the E-flite 40 AMP Brushless ESC is compatible with virtually any RC receiver, including E-flite SAFE receivers. The integrated BEC will power your receiver and provide the signal cable connection for throttle control from your transmitter.
- Is this ESC suitable for beginners? — If you already have an E-flite aircraft and are replacing a damaged or worn ESC, this component is straightforward to install. However, building an RC aircraft from scratch requires some technical knowledge and soldering skills. If you're completely new to RC flying, we recommend starting with a ready-to-fly E-flite aircraft or consulting our team for guidance on component selection and assembly.
