Detomo,
My setup uses the following Scalewarships components
12 v distribution board for power distribution, this unit I plug in a 11.1 3c lipo battery.
The board has a 5v 3A UBEC (Universal Battery Eliminator Circuit) I use this for powering the 8 ways switch
8 way switching unit
This unit I use to switch no / off , radar, LEDs in different areas ie hanger, nav, bridge etc.
LED Bus bars are used to power up multi LEDs for the flight deck. These bus bars are Switched using the 8way unit.
I’ve built a control box which houses a 10 channel receiver two 30amp mtronic ESC and a cooling fan. This control box can be unplugged and transferred to multi of other of my models.
The LEDs are 12v pre wired 0.5 mm purchased from Amazon
