I agree that it looks cool but with reference to Siegecrossbow's comment > I don't get how combining a roll with a vertical climb shows how capable the engine is compared to just a vertical climb on it's own.Is this the 1st time we have seen any such vertical climb with a WS-10 in a J10?

Yes it is, as a matter of fact. First time we see the J-10B doing maneuvers of any kind.

Anyone has the video for this? They are screen caps from a video. =GT posted them as CDF.

I would imagine quite an amount of engine power is required to perform the roll while at the same time doing the vertical climb. The question is how much of additional engine power this would mean.

the roll would be performed by the control surfaces, unless it's a TVC engine (even that TVC control would have to be written into the FCS first)

i assume it will be minimal, because it does not require any change in momentum of the aircraft

now if it's turning while climbing, or doing a loop, that would need all the engine could give

The additional drag caused by the maneouvre should be significant. Just imagine that the airflow across the aircraft is forced to change constantly in the roll maneouvre.
