The Graupner 4in1 Ultra Control 30A Race speed controller
addresses the need for race copter and FPV racers in a small and high-performance
design. The design uses high quality components and optimized software to
ensure super-fast and high performance under the most extreme race conditions.
The Ultra Control 30A Race is based on the open source
BLHeli software utilizing standard servo pulses, oneshot, multishot and D-Shot
which can be tweaked and updated by the user with standard BLHeli software.
The controller uses the modern 50 MHz Silabs processor which
has twice the clock rate of its predecessors which guarantees increased speed
and more precise timing at high speeds. The power amplifier is in a 3.3 x 3.3
DFN package while special FET drivers provide a more efficient and effective
freewheeling for better cooling of the power amplifier. The ceramic capacitors
used allow very fast start-up times and guarantee high operational safety.
The Ultra Control 30A Race detects normal (PPM) receiver
pulses and also responds to OneShot, Multishot or D-Shot pulses.
The controller and servo outputs are already optimized for
the Graupner GR-18, as well as the AIO Flight Controllers with HoTT receiver
and Racecopter settings.
The speed limit of the 30A Race is 400,000 rpm for 2-pole
To program the Ultra Control 30A Race and update it’s firmware
the Graupner USB interface cable P/N 7168.6 is needed.
