Key Features

• 50A Continuous Current Rating — The ESC is rated for 50 amps of continuous current with an impressive 300A burst capacity, providing ample power for aggressive acceleration and sustained high-speed running without thermal throttling or performance loss during demanding RC car sessions.
• Sensorless Brushless Motor (13.0R / 2950KV) — The 13.0R winding with 2950KV rating delivers a balanced combination of torque and top speed, making this motor ideal for 1/10-scale buggies and trucks that demand both acceleration and efficiency across varied terrain.
• Waterproof ESC Design — The fully waterproof speed controller construction allows you to run in wet conditions, through water crossings, and in damp environments without risk of electrical damage, extending the versatility of your RC car beyond fair-weather use.
• Flexible Battery Compatibility — This combo accepts 2-3S LiPo packs or 5-10 cell NiMH/NiCd batteries, giving you freedom to choose your preferred battery technology and find compatible packs from numerous UK RC suppliers.
• 6V / 3A BEC Output — The onboard Battery Eliminator Circuit supplies regulated 6V at 3 amps, allowing you to power your receiver, servo, and other electronics directly from the main battery without requiring a separate power source.
• 16 Adjustable Parameters — Using the included ET0106 programmable card, you can adjust throttle response, coast behaviour, neutral range, brake response, motor rotation direction, and more to create a setup that feels perfectly suited to your preferences and driving style.
• Compact Dimensions — At just 48 x 38 x 32mm without cooling fan and weighing only 95 grams, the ESC is small enough to fit into tight chassis enclosures whilst remaining extremely durable and reliable.
• Multiple Running Modes — Choose between Forward/Brake, Forward/Brake/Reverse, or Forward/Reverse configurations, with one-shot or two-shot reverse options available, allowing you to match the ESC to your driving preferences and race format requirements.
• Thermal Protection System — The ESC includes adjustable thermal protection that can be set to cut off at 95°C, 105°C, or disabled entirely, protecting your electronics from overheating during extended running sessions.
• Automatic Cell Detection — When using LiPo batteries, the auto cell-count feature automatically detects whether you're using 2S or 3S packs on power-up, eliminating the need for manual configuration changes between different battery types.

Technical Performance

The ETRONIX PHOTON 3.0 50A brushless system represents excellent engineering value and proven performance in the competitive 1/10-scale RC market. The 13.0R motor with 2950KV rating is specifically wound to deliver maximum efficiency and balanced performance characteristics across the typical voltage range of 2-3S LiPo (7.4V-11.1V nominal) or 5-10 cell NiMH chemistry. This winding specification provides strong initial torque for acceleration out of corners whilst maintaining reasonable top speed for open-field running, making it exceptionally versatile for buggies, truggies, and short-course trucks where varied terrain demands consistent performance. The 50A continuous current rating with 300A burst capacity ensures you'll never experience throttle limiting or performance degradation during intense driving, even when using high-discharge-rate batteries (50C and above). The waterproof ESC housing is constructed from durable materials that withstand the vibration, impacts, and environmental exposure typical of RC car use, whilst the compact 95-gram weight ensures minimal unsprung mass and better overall vehicle balance. The BEC output is generously rated at 6V/3A, which comfortably supplies power to standard receiver units and single servos without the need for additional BEC modules or external power distribution, simplifying your build considerably. Advanced features like drag brake, coast control, and flexible throttle response curves allow you to dial in the exact feel you want, whether you prefer aggressive immediate power delivery or progressive, controllable acceleration. The sensorless brushless technology eliminates timing issues and cogging that can occur with brushed motors, resulting in smoother, more linear acceleration curves that feel more responsive to throttle input compared to brushed systems.

Frequently Asked Questions

• Is the ETRONIX PHOTON 3.0 50A combo suitable for beginners in RC cars? — Yes, absolutely. The Photon 3.0 system is specifically designed as an ideal upgrade for those moving from stock brushed systems or as a perfect starting point for your first brushless RC car build. The straightforward setup, waterproof construction, and included programmable card make it very beginner-friendly whilst offering enough customisation to grow with your skills. The 2950KV motor is a sensible, mid-range power option that won't overwhelm new drivers.
• What batteries does this brushless RC combo require? — The Photon 3.0 accepts 2-3S LiPo batteries (7.4V to 11.1V nominal voltage) or traditional 5-10 cell NiMH/NiCd packs. Most UK RC enthusiasts use 3S LiPo batteries with this system, which provide excellent runtime, discharge rates, and performance. When using LiPo batteries, the ESC's auto cell-count feature automatically configures itself correctly on power-up.
• How does the 13.0R 2950KV motor compare to other Photon 3.0 motor options? — ETRONIX offers this combo in three motor variants: the 9.0R 4350KV (higher speed, lower torque), the 11.0R 3450KV (balanced mid-range option), and this 13.0R 2950KV (higher torque, lower top speed). The 13.0R 2950KV is ideal if you prioritise acceleration and low-end responsiveness, or if you're running on tighter, technical tracks where corner speed matters more than top speed.
• Is the ETRONIX PHOTON 3.0 waterproof? — Yes, the 50A ESC features full waterproof construction, allowing you to run in wet conditions, through water features, and in damp environments without concern for electrical damage. This makes it excellent for UK RC car use where weather conditions can be unpredictable.
• Can I adjust the ESC settings without purchasing additional programming equipment? — The ET0106 programmable setup card is included with this combo, so you have everything needed to adjust all 16 ESC parameters without any additional purchases. The card controls throttle response, brake behaviour, neutral range, motor rotation, and numerous other settings.
• What is the difference between the Photon 3.0 and the older Photon 2.1 series? — The Photon 3.0 is the newer generation, offering improved efficiency, better thermal management, enhanced programming flexibility with 16 adjustable parameters, and more refined throttle response control compared to the Photon 2.1 range. Both are reliable systems, but the 3.0 represents the current generation and is recommended for new builds.
• What vehicle types is this combo suitable for? — This 50A / 2950KV combo is specifically recommended for 1/10-scale off-road buggies, truggies, short-course trucks, and stadium trucks. These vehicle types all benefit from the balanced torque-to-speed ratio and reliable 50A current rating of this system.
