I know you hafto flash your ESCs with BLhelli to use oneshot but my question is

Do the BLhelli ESCs sold by flite test hafto be flashed to use one shot or can I use oneshot without re flashing the ESCs

Everywhere I look I cannot find anyone who talks about this. They are alwase flashing outher brands of ESC. I feal like this may be a stupid question because they are BLhelli and I want to test it out but with my fail safe currently at full throttle I don't feal like it's safe to do so.

So I ask does anyone know?
