Who makes the smallest brushless esc?

[Welshy40]

As the heading, Im currently redesigning an old broken esc with new stuff and may just rip out all the old and stick new internals in so I am after the thinnest and smallest brushless esc that is available capable of handling a 4.5 turn motor. Any ideas which is the thinnest and smallest?

I would guess at either Tekin RS Pro or Team Orion R10.
