I have some old escs off a emax 250 racer there are no receiver
leads wondering if anyone has figured out how to use them
They are some of the oldest ESC’s I’ve seen in a long while
I think they are SimonK 12Amp. (Non BLHeli)
At a guess…
RED - Lipo Postive from the PDB
Yellow - Signal wire to the FC
Black - Lipo Ground from the PDB
The 3 Connection point on the left are for the motor.
Hi Dwayne @indyair
Do you have a photo of the underside ?

Hi Dwayne @indyair
I’m sure Jason @DoomedFPV is correct with the wire colours.
I’ll see if I can identify it enough to get you the spec.
Might take a few days though
Cheers
