Make sure your board is flashed with the bdshot version of the Plane firmware.
The setup instructions are here: ESC Telemetry — Plane documentation

I Could not find the bdshot version of the speedybee wing board .
But thank you for taking the time to reply.
As per the Hwdef file;
PB7 TIM4_CH2 TIM4 PWM(1) GPIO(50) BIDIR
PB6 TIM4_CH1 TIM4 PWM(2) GPIO(51)
PB0 TIM3_CH3 TIM3 PWM(3) GPIO(52)
PB1 TIM3_CH4 TIM3 PWM(4) GPIO(53) BIDIR
PC8 TIM8_CH3 TIM8 PWM(5) GPIO(54)
PC9 TIM8_CH4 TIM8 PWM(6) GPIO(55)
PB14 TIM8_CH2N TIM8 PWM(7) GPIO(56)
PA15 TIM2_CH1 TIM2 PWM(8) GPIO(57)
PB10 TIM2_CH3 TIM2 PWM(9) GPIO(58)
PB11 TIM2_CH4 TIM2 PWM(10) GPIO(59)
PB15 TIM1_CH3N TIM1 PWM(11) GPIO(60)
PA8 TIM1_CH1 TIM1 PWM(12) GPIO(61)# LED
Sorry, I see that now. Looking at @dkemxr 's post it should work on pin 1-4. You won’t be able to use a servo in that same group so on the T1 you’ll end up with one of those four pins empty.
@Allister So I just blindly copied this w/o paying much attention. This implies only Chan 1&4 are Bdhot capable? Seems odd but you have the experience with these Speedybee FC’s that I don’t have.
Nope, helped a friend with one on betaflight once and that’s as close as I’ve got to put my hands on one.
I just “assumed” that the first two groups would handle bdshot, not just 1&4, but maybe that’s right. Yuck. I’d be tempted to stay with throttle filtering if that’s the case.
That makes more sense actually. Perhaps @andyp1per can answer that?
Yes 1-4, first two groups supported
