Hi All,

I am building a 9" Long Range qwad.  I am trying to fit 4x Favourite Swallow 60A ESC  (fixed wing) but all i get when i power up is constant repetetive beeps. I do believe it might have to do with throttle setup in the Tx but not really sure how to go about setting these ESC's up. Any help much appreciated ....

My setup is :

Matek FCHUB-12S with 440A Current Sensor PDB


Matek F722-SE

TBS Tango2 Pro and Crossfire nano Rx

BrotherHobby Avenger 2806.5 - 1300kV

do you use betaflight?

Ultimately i will use iNav on this quad but for now i am in Betaflight as i am more familiar with this config

your settup in the receiver tab is correct? do you get throttlerange between 1000-2000?
did you still tried to calibrate the esc? what firmware do they use?

It reads the stick input in the receiver tab, range i get on throttle is 988 - 2011
These ESCs are neither BLheli or BLheli 32 so i am stuck trying to program the esc's, you set them by by using the Tx apparently

i would flash the escs to the latest firmware, with blheli suite or the one for blheli_s escs.
what esc protocol do you use?

OP stated that he does not have Blheli esc.

@OP, most likely, you need to select PWM for ESC protocol.

im sorry, thanks for jump in voodoo
