The 3D Copter ESC
The Graupner Ultra Control 20 A 3D has been optimized especially for 3D Copters, eg the Graupner 3D Copter Alpha 300Q (Part No. 16530). The 20 A controller combines the highest quality components, the latest software, highest performance and minimum weight (15 g with cable).
The 20 A 3D uses the open source BLHeli software, version 14.2. The 20 A is currently the only open source flight controller with a built-in 50 MHz Silabs processor, whose updates and programming can be carried out via the Graupner update cable (item no. 7168.6). The strong Silabs processor is characterized by the high clock rate, which allows higher maximum speeds and precise timing at high speeds.
The Ultra Control 20 A features high-quality Power SO8 FET power amps. Special FET drivers guarantee an effective, active freewheel and cool the power amp. The field effect transistors of the Power SO8 are characterized by their low internal resistance of 1.6 mOhm. The Ultra Low ESR capacitors used guarantee super-fast reversal of rotation and super-fast start-up, as well as high operational reliability.
High-precision resistors ensure fast and precise engine start-up, and the preset Damped Light mode ensures extremely precise flight behavior.
The Graupner 20 A automatically detects normal (PPM) receiver pulses and OneShot Pulse. The
Servo paths and all other settings are already optimized for the Graupner GR-18 receiver and pre-set specifically for 3D Copter. The built-in receiver cable has a length of 50 mm. The speed limit for 2-pole motors is 400,000 rpm.


Characteristics:
  • Open Source BL Heli Software 14.1
  • Only open source ESCs with Silabs processor, updateable and programmable via the Graupner update cable No. 7168.6
  • New Silabs processor doubles the wire speed for higher maximum speeds and more precise timing at high speeds
  • High power SO8 FET condensators with low internal resistance 1.6 mOhm
  • Special fast FET drivers for more effective active freewheeling and cooler condensators
  • Ceramic capacitors for super fast start-up and high operational safety
  • High-precision resistors for faster and more accurate motor start
  • Damped Light mode preset for precise flight characteristics
  • Automatic detection for normal receiver pulses and OneShot mode
  • Preset servo travels and all other settings for the GR-18 and 3D Copter
  • Receiver cable 50 mm
  • Speed limit: 400,000 U / min with 2 pole motors
