Looks like she runs pretty good but I have a crick in my new from that sideways video! I would suggest a 35-38mm prop to start with.

Ah, my neck hurts from watching that video... LOL...

I have a 60cm hydro on a Scorpion 2221-8(typical trex450 motor) turning a 36mm prop, all slightly warm. Because you run a deep-vee try not to overdo it with propsizes as the ESC might explode from the increased AMPs
