GM Genius 75 ESC
Schumacher have announced the release of the new GM Genius 75 ESC. This hotly anticipated speedo has already won the EFRA 1/12th Euro’s earlier in the year. Especially designed for smaller applications such as 1/12th pan cars, it is equally at home in Touring Cars with stock 9.5T motors and above (2S LiPo) 3.5T (1S LiPo).
Features:
– Cooler operating temperature due to complete, light aluminium housing and special PCB design with extra-thick copper wires and optimized switching flanks. The flat design provides an extremely low centre of gravity.
– Top efficiency thanks to the new, even faster 16-bit processor and optimized software with newer, simpler operating software; providing longer operating time and greater performance
– For brushless motors (see operating voltage) and motors with brushes (up to 7.4V)
– Telemetry functions
– Automatic Hall sensor detection
– Storage/read-out of max rpms, maximum current, and temperature
– New brake and power programmes
– 10 user-programmable modes
– User-updatable firmware
– Soldering socket for easy replacement of wires
