In my mod:
http://www.gamesas.com/topic/1364733-relz-unrelenting-force-on-self-just-for-fun/page__fromsearch__1
I use the following commands:
"PushActorAway"
"ApplyHavokImpulse"
The problem is that the control of the camera during the flight is blocked.
"EnablePlayerControls" doesn't allow work.
How else can we allow control of the camera?
Thanks.

When the player is tumbling, the camera has a mind of it's own, and I haven't found any way to override it.

Yes. It is a pity.
