RC Servo FBL PWM Refresh Rate Demonstration

Bad News....I fried a servo.....Good News...the motor is still good, so i can by pass the fried board and just have small geared motor out put. So not a total loss, and I will find a use for it. Brand new to RC and servos and such, the one I fried was a cheapo so no big loss. Interesting to learn more about how these actually work and not just treat them like little 'black boxes'. - Cheers

I really do not understand why there are so many 'digital' servo's with all brands, in all sorts and sizes, but there are no receivers that can be told to use the refresh frequencies those servo's can handle. At least the ELRS folks have offered the option...

Thanks for sharing, this is really interesting. I'm interested to know if narrow band servos would work with transmitters like the Radiomaster TX16S which, if I understand correctly, has a range of 1000-2000us, where narrow band centres around 760us?

hello sir .may i use digital servos with 300 or 333hz refresh rate on control system that delivers fixed 495hz refresh rate.is it causes damages or variance in performance as digital known for accuracy.
