Please note I know im using quite old kit a lot of this is purely for testing.
Basically, I'm using the Emax BLHeli 20A ESC with Brushless Motor Emax MT2213. A replacement ESC I've bought doesnt have presolded bullet connectors (I assume it is a 3.5mm female bullet connector on the ESC?). When I solder up the bullet connector from a different ESC with wiring, it doesnt work at all.
Now its a pretty simple soldering job (almost impossible to get wrong) but doesnt work.
What are my alternatives? (Im sure the ESC works been tested elsewhere)
