The Best ESC for 250/300 Class Multi-Rotors

When comparing to regular 12A & 10A QAV ESCs, the XRotor-15A ESC’s current endurance
is improved by 25% to 50%. There won’t be any problem to pair it with 1806 size motor &
2204 size motor. They will provide high power for 250/300 class multi-rotors.

2204 size 2300KV motor, 5045 propellers, the input voltage of 11.4V.

Conclusion:The XRotor-15A ESC is much better than other ESCs for QAV 250/300.

OneShot
Mode Supported

Besides regular throttle signals with a refresh rate
below 500Hz, the XRotor-15A ESC also supports
OneShot mode throttle signals. In this mode, the
communication between the flight controller and ESC
becomes more agile, the throttle linearity is better,
and the response speed is much faster.

DEO (Driving Efficiency
Optimization)

The XRotor-15A ESC adopted the DEO technology which has
multiple advantages:
● Active braking. When reducing the throttle amount, the motor will
decelerate very quickly. This feature enables pilot to more easily
perform all maneuvers like sharp turns, altitude rapid changes, and
sudden braking.
● Higher driving efficiency, longer flight time.
● Lower ESC temperature.
* Different companies call this technology by different names;
“SimonK” calls it “Comp_PWM”, “BLHeli” calls it “Dampaning-light”
and Kontronik calls it “Active Freewheeling”.

Highly Intelligent

Highly intelligent and adaptive default settings meet almost all
applications. The ESC is extremely easy to use.

Twisted-Pair Signal Cable
Reduces Interference

The twisted-pair throttle signal cable effectively reduces
interference produced in signal transmission and makes
the flight much more stable and reliable.
