Radio-controlled electric motor BF32-18A variator

Lighter and more compact than most controllers on the market, these next-generation ESCs are also more powerful, more efficient, and directly usable on board an aircraft (3S to 6S) without requiring any programming before use*.

Pro-Tronik controllers can provide the motor with the continuous current indicated on the label (example: 23 A for the BF32-23), provided they are properly ventilated.

Advanced users or those equipping a specific model can still access the many adjustable parameters to precisely and effectively adapt performance to the motor, battery, and model type (airplane, glider, drone, boat, car, etc.).

The exceptional performance of the electronics, including the 32-bit ARM processor, ensures extremely precise motor control in all circumstances, exceptionally high efficiency, and optimal battery protection, keeping the pack in the best performance conditions.

Pro-Tronik controllers are designed exclusively to drive a brushless electric motor installed in a model via a proportional radio control system.

Pro-Tronik controllers can provide the motor with the continuous current indicated on the label (example: 23 A for the BF32-23), provided they are properly ventilated.

Technical specifications:

• 18A controller for brushless motor

• BEC output 5.5V 2.5A (4A max)

• Power supply: 2 to 6s LiPo

• Dimensions: 30 x 14 x 4 mm

• Weight: 11g

• Easy programming via your computer or smartphone/tablet using interface S03878035 (sold separately)

• Or classic “beep-by-beep” programming using your transmitter

Recommended motors for BF32-18A controller: 2210-1100, 2210-1400

*Since it's unrealistic to test all possible configurations, direct use without any parameter adjustment applies only to an aircraft powered by a 3 to 6S LiPo battery. Other configurations, especially with 2S, may require parameter adjustments depending on the setup.

Treat yourself to a high-end Brushless controller at the price of a standard model, because your models deserve it!

Here’s why you’ll now choose our BF32 controllers:

• Wide compatibility with all types of models:
  BF32 controllers are perfectly suited for standard planes, 4D planes (thrust reversal), powered gliders with or without gearbox, drones, etc.
• Ready to use:
  All BF32 settings are factory-optimized for immediate use, but many parameters remain accessible should you need to fine-tune the behavior for your model.
• Compact and lightweight:
  Our BF32 controllers offer one of the best weight/power/size ratios on the market, helping you gain a few extra seconds of flight.
  Example: the BF32 33A fits easily into the narrow fuselage of an F5J and saves precious grams.
• Reliability:
  The electronics in BF32 controllers rely exclusively on high-end, oversized, proven, and reliable components.
• Throttle response:
  A BF32 controller responds up to 5 times faster to throttle stick movements than a standard controller. Flight control becomes both sharper and more precise.
• Excellent efficiency:
  Thanks to their exceptional efficiency, BF32 controllers deliver more power and longer flights than standard controllers, while generating less heat.
• Optimized motor start-up:
  A BF32 controller enables a smoother, quieter, and more powerful motor start than most standard controllers.
• Reliability and performance:
  The processing power of BF32 controllers far exceeds that of standard models, ensuring accurate and reliable motor control at any Kv rating up to 250,000/pole.
• Effective propeller brake:
  Disengageable, more efficient and adjustable if needed, it perfectly adapts to your propeller size and protects your model by reducing strain and jolts — even with a gearbox.
• Powerful and reliable SBEC:
  The BF32 SBEC can safely and efficiently power up to 6 servos. That’s why BF32 controllers are often used in demanding F5J gliders.
• Built-in lost model acoustic beacon in the ESC:
  BF32 controllers include a lost-model acoustic beacon that activates automatically, even if the transmitter link is lost or fails.
  No more stress about losing your model — and at no extra cost or weight!
• Enhanced pilot and motor protection:
  BF32 controllers feature a sophisticated analysis system to prevent accidental start-ups and can cut the motor if the propeller is blocked.
  Your safety is priceless.
• Battery protection:
  BF32 controllers precisely monitor battery status and manage motor cutoff optimally to make the most of every second of flight while extending battery lifespan.
• Built-in overheating protection:
  BF32 controllers are equipped with multiple internal protection circuits, including thermal protection, to reduce the risk of performance loss or damage.
