/diy/ - Do It Yourself

>>1685435
The BEC you're seeing in these builds is just a 5V regulator, which takes power from VBAT & provides 5V power to the servos, exactly as you explained. I have no idea why this hobby insists on calling them 'BEC' instead of just 'voltage regulator', I've literally not come across a single other situation in which the term 'BEC' is used & I've been using voltage regulators for umpteen purposes for 20 years.

If you're using something like an Omnibus F4 board then powering servos from a separate 5V BEC/regulator is a good idea, as the 5V regulator built into an Omnibus or similar isn't very powerful & if you overload it you risk losing power to other critical components that are powered by it (such as your RC receiver).

However there are now wing specific FCs like the Matek F405-WING or F411-WING or F722-WING which have separate high power regulators just for the servos & will simplify the build substantially. In fact the Matek F405-WING was possibly the first FC build specifically for iNav (& also received an Arduplane image very quickly). I never actually got around to flying mine (built it into a Nano Talon) but I'm getting a car soon so will have access to more wing suitable locations to try it out at.

In /rcg/ we discuss anything & everything remote controlled - multirotors, fixed wing, cars, rovers, helis, boats, submarines, battlebots, lawnmowers, etc.
