Technical Performance
The E-flite Motor 10: Ultimate 2 represents a refined approach to electric motor design for fixed-wing RC aircraft. With a 1300Kv rating, this brushless motor delivers responsive power delivery essential for stable flight across varying flight conditions. The motor integrates seamlessly with compatible ESC units from E-flite, including the 40-Amp Brushless ESC: Opterra and 40-Amp ESC: Ultimate 2 variants, creating a complete, harmonised drivetrain system. Brushless technology ensures efficient power conversion, extended operational lifespan, and minimal maintenance requirements compared to traditional brushed alternatives. The motor's engineering prioritises smooth acceleration, predictable throttle response, and reliable sustained performance throughout your flight session. Build quality reflects E-flite's attention to detail and commitment to dependable operation in real-world flying scenarios. This motor has been validated across multiple airframe types including the Ultimate 2 BNF Basic with SAFE 954mm variant, Opterra 2m wing configurations (both BNF Basic with and without AS3X, plus PNP variants), Cirrus SR22T 1.5m models (BNF Basic and PNP), and Timber 1.5m aircraft with float landing gear. The motor's thermal management and electrical characteristics have been carefully calibrated to prevent overheating whilst delivering full power output throughout typical flight sessions, ensuring consistent performance from first takeoff through final landing.

Frequently Asked Questions
- What aircraft models does the Motor 10: Ultimate 2 fit? — This motor is designed as a Standard Part for the Ultimate 2 BNF Basic with SAFE 954mm airframe (part EFL10850), and is listed as compatible with the Opterra 2m Wing BNF Basic with AS3X, Opterra 2m Wing BNF Basic with AS3X and SAFE Select, Opterra 2m Wing PNP, Timber 1.5m BNF Basic AS3X with Floats, Timber 1.5m PNP with Floats, Cirrus SR22T 1.5m BNF Basic, and Cirrus SR22T 1.5m PNP. Always check your specific airframe's manual and parts list to confirm compatibility before installation.
- Is this a genuine OEM replacement motor? — Yes, this is an authorised E-flite motor manufactured by Horizon Hobby to original equipment manufacturer specifications. It is not an aftermarket alternative or clone. When purchased from RC Model Shop, you receive a genuine product backed by E-flite's quality guarantee and warranty support.
- What ESC should I pair with this motor? — E-flite specifies the 40-Amp Brushless ESC: Opterra or the 40-Amp ESC: Ultimate 2 as compatible options. These ESC units have been tested and validated specifically for use with the Motor 10: Ultimate 2, ensuring optimal performance and protection for your system. Always use an ESC matched to your battery voltage and current requirements.
- What is the 1300Kv rating and why does it matter? — Kv (kilovolts) represents the motor's RPM per volt applied. A 1300Kv motor will spin 1300 revolutions per minute per volt of battery voltage. This rating has been specifically chosen for the Ultimate 2 and compatible airframes to provide the optimal balance between torque (pulling power) and rotational speed for steady, controllable flight without excessive current draw or motor overheating.
- Can I use this motor with a different ESC than recommended? — Whilst other brushless ESCs may physically fit, E-flite has validated this motor specifically with their 40-amp ESC options. Using a different ESC may result in suboptimal performance, potential overheating, or inadequate protection. We recommend following the manufacturer's specifications for best results and system reliability.
- How long will this motor last? — Brushless motors like the Motor 10 have no brushes to wear, resulting in significantly longer operational lifespan compared to brushed alternatives. With proper maintenance (checking for debris, ensuring adequate cooling airflow, and avoiding moisture ingress), you can expect years of reliable service across hundreds of flight hours.
- Is this suitable for beginners? — The Motor 10: Ultimate 2 is a replacement component intended for those already operating E-flite aircraft. It is not sold as a complete ready-to-fly system. If you are new to RC aircraft flying, we recommend purchasing a complete BNF (Bind-N-Fly) or RTR (Ready-to-Fly) package rather than individual components. However, if you already own a compatible airframe and require a replacement motor, this is the correct choice.
- What is the difference between this and other E-flite motors? — The Motor 10 designation indicates a specific motor size and performance class within E-flite's motor range. The 1300Kv rating and mechanical specifications have been optimised for the Ultimate 2 and compatible models. Other E-flite motors with different Kv ratings or designations are engineered for different airframe types and will not provide the same performance characteristics if substituted.
- Is this motor brushless or brushed? — This is a brushless electric motor. Brushless motors use electronic switching rather than physical brushes to commutate power, resulting in higher efficiency, cooler running temperatures, longer lifespan, and lower maintenance requirements compared to brushed designs commonly used in older RC aircraft.
