Due to the ever increasing demand for reliable ESCs for multirtors we are planning to test the new line of MGM Compro Multirotor ESCs. From our past great experiences with their 32bit 400A 16S ESC for surface and marine use, we are very excited to test the latest 32bit multirotor ESCs. Especially the internal data logging feature (last 12 minutes) that we have come to love on the surface speed controllers is standard on the xxxx-3 M  speed controllers. Online upgradable firmware makes the ESC future proof as well. We will keep everyone updated as we progress with this exciting test.

“This motor speed controllers provide very quality, smooth and quick motor controls for multicopters.
Controllers are designed for the best result in multicopters and therefore have extremely quick response time to control signal.

Controller uses the best available power MOSFET and synchronous PWM for achieve very high efficiency.
They feature very advanced (state-of-the-art) algorithms of motor control as well as safety of operation. Controller concept is based on a long experience with control of both sensorless BLDC motors in very heavy and demanding operating conditions. For driving are used very powerful 32-bit ARM microcontrollers.
To enable our customers to exploit the newest developments and satisfy new requirements, SW update of the PC programs as well as the firmware update of the controller can be carried out by the customer himself/herself though the internet at any t ime. Thanks to this are easily accessible customer-specific modifications and adjustments FW”
