Anyone try it?
I just want 7-10 min of mild 3d or camera flying.
What do you think?
Will it work?

The Century 600+ motor works well but on 6S. A ready to fly E550 is a pretty heavy beast and I'd think it's too much for the 550 motor and a 4S setup.

Well Im running 600's instead of 620's
FXaero models moto calc says

Motor: cen550 | Kv: 1470 rpm/v | Shaft Size: 5 mm | Weight: 7.2 oz. | Cell Count: 4 | Pinion: 11 | Battery: Lithium
Maximum rotor speed is approximately: 2156 RPM .
Heavy load rotor speed is approximately: 1858 RPM

No feild for rotor size but I assume by selecting
e-rappy550 from the drop down it sets the blade size.

I just hoverd it on the 600 motor/ 15c 4000 4cell lipo for about 5 min.
Not a drop of heat from the battery or motor.
RPMs sounded like around 1600/1700 but I was in the back yard.
So no FF.

I think I will just buy a data logging amp meter and go by the #'s
like I do on my fixed wings. Then I can be sure.
