The OMEGA-3 3 amp ESC has been revised and updated.
The RX no longer plugs in upside down on the ESC pcb.
For a number of reasons I have gone back to using servo leads to connect the RX to the PCB.
Mostly because I can no longer get the DSM2 compatible Right Angle mount servo pin RX’s. End mount servo pin RX’s would have stuck up at right angles to the pcb.
This latest version can now use any brand of 2.4 GHz R/C.
