Brushless Protronik BF70A U-BEC 4A Speed Controller for airplane

The Protronik brushless controllers have been developed to offer precise, reliable, and high-performance control to all aeromodelling enthusiasts.

Compact, lightweight, and powerful, each Protronik ESC ensures optimal management of the motor and battery thanks to an advanced microcontroller.

This range of Protronik brushless controllers covers a wide range of needs, from small electric planes to brushless controllers for large RC planes, with models from 12A to 120A compatible with LiPo 2S to 12S.

Each RC airplane brushless ESC has precise settings to easily adapt the operation to the motor, battery, and model used.

Pro-Tronik controllers can be configured directly via the throttle of your radio.

However, for simpler, faster, and more precise adjustment, we recommend using the EPRG-3 programming card, ideal for efficiently setting up your Pro-Tronik controller.

ESC BFu 70A U-Bec 4A - Black Fet series

Dynamic test, controller heating:
21 volts, 61A => at 120 sec = 58°C / at 180 sec = 71°C
21 volts, 66A => at 120 sec = 75°C / at 180 sec = 90°C

Months of development, choosing the best latest-generation components, multiple tests and laboratory trials now allow us to present what can be considered the best controller available on the market!

Some may argue that, for such a price, one cannot have the "best".......
The only way to verify this is not to try it?
Where is the risk? A product developed in France, sold by a French company, with a French warranty.......

IMPORTANT INFORMATION: the EPRG-3 programming card (S03878301) is necessary to set the number of LiPo cells you will use with your controller. This card greatly facilitates programming and is compatible with both new and old versions of our controllers.

IMPORTANT: unlike many brands that announce imaginary values, the permissible intensity of Pro-TroniK controllers is a continuous data.You can therefore select your Pro-Tronik controller without fear based on the maximum consumption of your motor.
