The upgrading of FPV racing drones is so rapid that no one has ever expected. FPV racing drone ESC entered 32-bit generation in this year. Boosted by the demand of some top pilots for big power, the continuous current of one single ESC has exceeded 40A. At this moment, Flycolor officially releases 32-bit 50A ESC X-Cross BL-32. It’s so far the strongest current in FPV racing drones industry. From now on racing drone fans don’t need to worry that the ESCs get burnt in flight and enjoy the high speed experience brought by the racing.
Check out the two video clips about X-Cross BL-32 50A tests:
We can see from the video that the X-Cross BL-32 works perfectly at continuous current 45A under voltage of 24V(6S). The video only shows 5 minutes but the BL-32 can work for very long time.
We can see from the video that when the battery voltage was 24V (6S), the maximum current was up to 68A. The motor eventually burnt out when the continuous current exceeded 60A for more than 10 seconds. But the X-Cross ESC still worked. It’s obvious that the capability of withstanding current of BL-32 50A is extraordinary. (P.S. When the motor is burnt out, if the circuit is shorted out it can damage the ESC as well.But if the circuit is cut off, it won’t damage the ESC)
Here is the details of this X-Cross BL-32 ESC.
The PCB size of X-Cross BL-32 50A is 33x16x6mm. And it weighs only 10g. It adopts ARM 32-bit Cortex MCU and it’s supported by BLHeli_32 firmware.
X-Cross BL-32 50A supports PWM, Oneshot 125, Oneshot 42, Multishot and all Dshot signals up to Dshot1200. Dshot is digital signal. It has less interference and it doesn’t need to calibrate throttle range. Dshot1200 has quicker response than Dshot600. And the throttle become smoother.Supporting Damped Light of braking which increases the flexibility of flight.
X-Cross BL-32 50A adopts top grade imported MOSFET which is stable, low internal-resistance and strong current durable. There is an aluminum alloy heat sink on top of MOSFET which can abstract heat efficiently.
The solder pad is produced by metallized edge technique. It’s covered by metal all around.The contact surface is enlarged and soldering point become more solid and stable.
X-Cross BL-32 50A can support higher KV motors and more powerful loads. It’s suitable for professional FPV drone racing. It will be the favorite assistant for FPV pilots.
