The 3D Copter 4 in 1 ESC


The Graupner 4 in 1 Ultra Control 15 A Race BL Heli S is the ideal 4-speed controller for all 3D Multicopter. The 15 A Race combines a compact design, low weight, super-fast response times and settings optimized for Racecopter. In addition, the 4 in 1 controller has a power shunt and amplifier for current measurement.
The Ultra Control 15 A has the open source BLHeli S software for standard servo pulses, oneshot, multishot and D-Shot installed. The flight controller uses the modern 50 MHz Silabs processors. The processor has twice the clock rate of its predecessors. This guarantees higher maximum speeds and precise timing at high speeds.
The power amplifier is located in a 3.3 x 3.3 DFN package. Special FET drivers provide a more effective active freewheel and better cooling of the power amplifier.
The ceramic capacitors used allow very 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 Ultra Control 15 A Race detects normal (PPM) receiver pulses, but also OneShot, Multishot or D-Shot. The controller and servo paths are already optimized for the GR-18, as well as the AIO Flight Controls with HoTT receiver and the Racecopter settings.
The speed limit of the 15 A Race is 400,000 rpm for 2-pole motors.
The 50 MHz Silabs processor of the 15 A can be updated and programmed using the Graupner update cable (Part No. 7168.6) and the included adapter. An adapter cable is needed for soldering.
