The miniature multicopter or indoor models ESC


The Graupner UltraControl 7 A Race BL Heli S is the ideal ESC for all Miniature Multicopter or Indoor models, which are especially important for size and weight. The 7A Race combines a compact design, low weight, fast reaction times and optimized settings for Racecopter.
The ESC is programmed for the bidirectional mode forward and reverse function. So it's also usable for small cars and boats.

The UltraControl 7 A has installed the Open Source BLHeli S software for standardservopulse, oneshot, multishot and D-Shot. The flight controller uses the modern 50 MHz Silabs processors. The processor has a twice as high clock rate compared to its predecessors. This guarantees higher maximum speeds as well as precise timing at high speeds.

Special FET drivers ensure a more active freewheeling and better cooling of the output stage. The ceramic capacitors used allow fast start-up times and guarantee high operational safety. The controller has pre-activated the Damped Light mode. This allows a more precise flight behavior. The speed limit of the 7 A Race is 400,000 RPM with two-pole motors.
