Brushless Protronik BF32-33A Speed Controller for Aircraft

NEW BF32-33A Controller - BF32 seriesLighter and more compact than most controllers on the market, these next-generation speed controllers are also more powerful and directly usable on board an aircraft (3s to 6s) without requiring any programming before use*.Thanks to the particularly careful factory presetting and the intelligence of the 32-bit ARM processor, all you need to do is take the controller out of the packaging and plug it into the aircraft to start flying.Expert modelers or those needing to equip a specific model can, however, access the numerous adjustable parameters to precisely and effectively adapt their operation to the motor, battery, and model regardless of its type (airplane, glider, drone, boat, car, etc.).The exceptional performance of the electronics, especially the 32-bit ARM processor they are equipped with, ensures extremely precise motor control, particularly high efficiency, optimal battery safety, maintaining the pack in the best performance conditions.Pro-Tronik controllers are exclusively designed to control a Brushless electric motor installed in a model via a proportional radio control system.Pro-Tronik controllers can provide the motor they control with the continuous current value indicated on the label (example: 23 A for the BF32-23), provided they are properly ventilated.Technical characteristics:

• 33A Brushless motor controller
• BEC output 5.5V 4A max
• Power supply from 2 to 6s LiPo
• Dimensions: 30 x 15 x 7mm
• Weight 18g
• Easy programming from your computer or smartphone/tablet using the S03878035 interface (sold separately)
• Or classic "beep" programming using your transmitter

Engines recommended for BF32-33A controller: 2215-3100, 2215-3500, 2610-1000, 2610-1100, 2610-1200, 2810-800, 2810-1000, 2810-1200, 2615-1050, 2615-1300* As it is unrealistic to test all possible configurations, direct use without any parameter adjustment only applies to an airplane model powered by a 3 to 6S LiPo battery. Other configurations, especially under 2S, may require parameter adjustment(s) as needed.

Get yourself a high-end Brushless controller for the price of a classic model, because your models deserve it!

Here's why you will now choose our BF32 controllers:

• Wide compatibility with all types of models:The BF32 controllers are perfectly suited for classic airplanes, 4D airplanes (thrust reversal), motor gliders with or without gearbox, drones, etc.
• Ready to use:All BF32 settings are factory-optimized for immediate use, but many parameters are available for you to fine-tune the behavior to the model if needed.
• Compactness and weight:Our BF32 controllers offer one of the best weight/power/dimensions ratios on the market, allowing you to gain a few extra seconds of flight time.Example: the BF32 33A fits easily into the narrow fuselage of an F5J and helps save precious grams.
• Reliability:The electronics of the BF32 are based exclusively on high-end, oversized, proven, and reliable components.
• Throttle response:A BF32 controller reacts up to 5 times faster to throttle stick movements than a traditional controller. The control is both more precise and more responsive.
• Excellent efficiency:Thanks to their exceptional efficiency, the BF32 controllers allow you to achieve more power and longer flights compared to a traditional controller, with less heating.
• Optimized motor start:A BF32 controller enables a smoother, more powerful, and quieter motor start than most traditional controllers.
• Reliability and performance:The computing power of the BF32, much higher than that of traditional controllers, ensures reliable and precise power control of the motor, regardless of its Kv up to 250,000/pole.
• Efficient propeller brake:Disengageable, more effective, and adjustable if needed, it adapts perfectly to the size of the propeller and protects your model by limiting stress and jerks—even with a gearbox.
• Powerful and reliable SBEC:The SBEC of the BF32 can efficiently and safely power up to 6 servos. This is why BF32 controllers are often used in particularly demanding F5J gliders.

• Integrated sound beacon for lost model search in ESC: The BF32s integrate a sound beacon that triggers automatically, even if the connection with the transmitter is lost or faulty. No more anxiety about not finding your model — and all this without any additional cost or extra weight!
• Enhanced pilot and engine protection: The BF32s feature a sophisticated analysis system that prevents any unintentional start-up and can shut down the engine in case of propeller blockage. Your safety is priceless.
• Battery protection: The BF32s precisely measure the battery's status and optimally manage engine cutoff to make the most of every second of flight while extending the life of your batteries.
• Built-in protection against overheating: The BF32s are equipped with multiple internal protection circuits, including one for temperature, reducing the risks of performance loss or damage.
