There are many servo testers and even some servo centering tools available on the market. I didn’t find though the one I wanted to have, with selectable 1500/1520µs PWM outputs and also with 760/960µs outputs for helicopter fast tail servos.

Of course Flybarless controller unit can be always used to center servos, but I like to mount FBL unit at very end, without bothering about it during the build process.
