ZMR250 Build – Part 2 – Power & ESC Check

In this video I hook up power to the fpvmodel PDB and to the EMAX 12A ESC. I'm trying to decide whether to solder the Sunnysky motors directly to the ESC or to the ESC leads. Removing the heatshrink from the ESC shows what looked like dodgy solder job touching the pins of the ICs. I wondered if they were going to work at all. After hooking up power and successfully testing them, I decided to use the ESC leads to connect to the motors for two reasons;

1. Unlike other ESCs that have the three points at the end of the ESC to connect to the motor wires, these EMAX 12A ESCs have them along the middle of the board which means the wires would be staggered (different lengths).
2. The connections are inbetween ICs and some of them make contact with the legs of the ICs. I don't want to break the connections with a messy soldering job.
