I am new to building electrics and I have a question. I bought a GWS 400 ESC for my P-51 and the wires on it are 16ga. The wires comming from the 300C motor are 22ga with what I believe is a JST connector and the same comming from the battery. Is it ok to hook 22ga and 16ga wires together? Should I solder them direct or put connectors on them? The ESC is 15amp by the way. Thanks for any help.
