The current build I'm doing uses 4 brushless motors & esc's in parallel. I will use the red wire in the receiver lead from esc & seal off the other 3 from use. These terminal blocks seen in this pic come in handy for hooking many electrical devices to one power source through one on/off switch.
The battery & switch side, you just use wire loops for the + & - across the bar. And connect each device on the other side.
The terminal strip makes it easy to change out electrical components should you wish to change to something else or replaced a failed a component vs having to cut & re solder all back together.

I use a simple rocker switch similar to these between battery & terminal strip to turn on/off main power.
