Key Features
- 4mm Motor Shaft Compatibility — This adapter is engineered specifically for electric power systems utilising a 4mm motor shaft, ensuring a perfect fit and secure connection without wobbling or runout issues that could affect your RC model's performance or safety.
- Collet-Style Design — The collet mechanism provides a reliable clamping action that grips your propeller shaft securely without requiring excessive force, reducing the risk of shaft damage whilst maintaining absolute concentricity for balanced flight.
- Premium Aluminium Construction — Machined from high-grade aluminium, this adapter delivers an optimal balance between weight savings and structural integrity, ensuring your RC model remains light whilst maintaining the rigidity required for precision performance.
- Durable Hardware Component — As a genuine E-flite part, this adapter is built to withstand the vibration and stress associated with electric motor operation, providing long service life whether you're flying RC aircraft daily or using it occasionally.
- Compact, Tidy Installation — The efficient design minimises the installation footprint, allowing you to create neat, professional-looking builds that maintain proper weight distribution and aerodynamic balance in your RC models.
- Genuine E-flite Quality — Sourcing original E-flite hardware guarantees compatibility with E-flite motors and accessories, avoiding the fitment issues and performance inconsistencies sometimes encountered with third-party alternatives in the UK RC market.
Technical Performance
The E-flite Prop Adapter with Collet represents the pinnacle of small-scale hardware engineering for electric RC applications. Manufactured to exacting tolerances from premium aluminium alloy, this component is engineered to handle the sustained vibration and rotational forces generated by brushless and brushed electric motors. The 4mm shaft size makes it compatible with a comprehensive range of small electric motors commonly found in modern RC aircraft, lightweight drones, and electric-powered RC vehicles throughout the UK hobby market. The collet-style clamping mechanism ensures runout is minimised to professional standards, critical because even minimal shaft wobble can cause propeller imbalance, vibration, and potential structural damage to airframes. The aluminium material has been selected for its exceptional strength-to-weight ratio, ensuring the adapter adds minimal mass to your RC model whilst providing the rigidity necessary to transmit motor torque without flex or deformation. Every E-flite component undergoes quality control scrutiny, meaning you can trust this adapter to perform reliably whether you're conducting high-speed aerobatic manoeuvres or steady cruising flight.

Frequently Asked Questions
- What motor shaft size is this prop adapter designed for? — This E-flite adapter is engineered specifically for 4mm motor shafts, making it compatible with small electric motors commonly used in RC aircraft and electric RC models throughout the UK hobby community. Always verify your motor's shaft diameter before purchasing to ensure correct fitment.
- Is this suitable for beginners and experienced RC flyers? — Yes, this adapter is suitable for anyone operating electric RC models, from absolute beginners assembling their first RC aircraft to experienced competitors. The collet design is user-friendly and forgiving, requiring no special tools or expertise to install correctly, though experienced builders will appreciate its precision engineering.
- What is a collet adapter and why is it better than a simple push-fit design? — A collet adapter uses a tapered sleeve (the collet) that clamps around your propeller shaft as you tighten the central nut, distributing pressure evenly and creating a secure, vibration-free connection. This is superior to simple push-fit adapters because it prevents shaft slippage, reduces vibration, and minimises damage to shaft splines, extending the life of both your motor and propeller.
- What type of motor can I use this with? — This 4mm adapter is compatible with any electric motor (brushless or brushed) featuring a 4mm output shaft. This includes many small E-flite motors and equivalent third-party options designed for similar RC applications, though E-flite hardware pairs perfectly with E-flite motors.
- What propellers can I fit to this adapter? — Any propeller with a hub bore diameter compatible with your 4mm shaft can be used with this adapter. The adapter itself accommodates standard RC aircraft propellers in the small-scale range, though you should always consult your RC model's documentation for recommended propeller specifications to ensure optimal performance and safety.
- Is this an essential spare part to keep? — Yes, spare prop adapters are highly recommended for anyone with electric RC models. A bent or damaged adapter can ground your entire RC aircraft unexpectedly, so keeping a spare ensures you can return to flying quickly. The modest cost of the EFLM1924 makes it a smart investment for reliability.
- How do I install this prop adapter onto my motor shaft? — Installation is straightforward: slide the adapter onto your 4mm motor shaft, position your propeller hub, then tighten the central collet nut carefully using an appropriate wrench. Tighten firmly enough to prevent shaft rotation under load, but avoid over-tightening which could damage the shaft or collet mechanism.
