I recently built a 5-inch quad using:
- Diatone Mamba F405 Mk2 F40 Mk2 3-6S 30x30 Stack/Combo (F4 FC / 40A 4in1 ESC)
- Motors: iFlight Xing-E PRO 2207 1800Kv Motor with DShot 600 and 4S battery cell. I didn't notice any problems with the build when I did a test flight.
I am now trying to build a larger drone (850mm or 950mm X-Class). I was wondering if the same flight controller/esc combo would work for motors:
Cobra CM-2820/16 Multirotor Motor, Kv=740 (link)
iFlight XING X4214 400KV Motor (link)
The cobra motor specifies that the pwm frequency is 8khz, but I didn't see any details on pwm frequency for the other brushless motors. So now I'm not sure whether pwm frequency is a parameter I need to consider when choosing an FC/ESC for a motor. Or is the 8khz a standard frequency that all FC/ESCs support? Usually I just make sure the ESC supports the maximum amp from the motor and propeller combination I plan to use, and that I have the correct LiPo battery cell count.
