The Best ESC for 250/300 Level 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 level multi-rotors
Temperature Comparison
Throttle Amount | XRotor-15A ESC | BLHeli-12A ESC |
50% | 62.5℃ | 90.6℃ |
60% | 71.5℃ | 104℃ |
70% | 82.5℃ | 118℃ |
100% | 89.7℃ | 120℃ |
Test Equipment & Conditions:
XRotor-15A ESC & BLHeli-12A ESC (both use the default settings without any adjustment),
2204 size 2300KV motor, 5030 three-blade propellers, the input voltage of 12.6V, and each test was run for 8 minutes.

Conclusion:The XRotor-15AESC 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”.
