The ESC is built with TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. We also provide a humongous 1500uF low ESR capacitor, ensuring clean data from the gyro to the FC. Tested by 2 top racing pilots with both over 1500 packs, or you can put it to the test yourself.
Wanna crank it up to 128KHz PWM? Why not?
With F4 MCU, you can set the PWM frequency up to 128KHz. Find the best PWM frequency* to get for your build without any limitation.
* The ideal PWM frequency for each build varies depending on the frame, motors, props, and other factors. Higher PWM frequency doesn't necessarily means smoother flight.
If the default 48KHz is not working for your build, you can increase the value gradually until you find the sweet spot.
Check your motor temperature to avoid overheating.
CNC heat sink shield = no overheating in any condition
Built with high-quality CNC heat sink to significantly reduce the heat from your MOSFETs ensuring stable current flow at a high throttle position.
Great benefit in a stylish blue finish.

Love the super fast shipping
This is not a product review as i have not installed yet. Its just a review of excellent customer service and fastest shipping. I ordered my speedybee stake and matek flight controller on Thursday morning and i received it the next day morning. I thought this weekend is no fly for me but i was wrong. The speedybee and matek fc was packed nice and cozy. The product looks excellent. Cant wait to install it and get high again. Thanks
I haven't had such a great experience that comes close to the great experience I had with these guys - ordered the battery then the next day it arrived - WHAT???? I couldn't believe it and it was an awesome surprise - thank you so much. Regards - Motion Mad Media
