Yes, rather than toed-in ala speedbrake in the Super Hornet where it helps get the nose up at low speed so one assumes the same thing for the F-35C with perhaps a crosswind component dictating the right 'lean'? [All computer controlled]
F-18 rudders during take-off October 25th, 2009
http://cencio4.wordpress.com/2009/10/25 ... -take-off/
"...why the F-18 (both C, E and F versions) has the rudders deflected inwards during catapult launches.
That position of the rudders is common to all the Hornets, not only those departing from the flight deck of an aircraft carrier: the rudders are deflected to help the nose raising as the aircraft leaves the ship. Since the vertical fins are angled outwards, deflecting both rudders inwards gives a downward component of lift, which acts behind the centre of graviting generating a momentum that assists the elevators." |

| It also increases drag above the CG |

Side View Video of the first TC-7 steam catapult at PaxRiver fling.
First F-35C catapult launch at NAS Patuxent River 04 Nov 2011 Video
http://www.youtube.com/watch?feature=pl ... p26HGaCveI
"Uploaded by NAVAIRSYSCOM on Nov 8, 2011
NAVAL AIR SYSTEMS COMMAND, PATUXENT RIVER, Md. -- Navy test pilot Lt. Chris Tabert flies F-35C test aircraft CF-3 off the TC-7 steam catapult at NAS Patuxent River Nov. 4. The launch was the first time the test catapult here launched an F-35C Lightning II Joint Strike Fighter. Previous catapult testing occurred in Lakehurst, N.J. The F-35C carrier variant of the Joint Strike Fighter is distinct from the F-35A and F-35B variants with its larger wing surfaces and reinforced landing gear to withstand catapult launches and deck landing impacts associated with the demanding aircraft carrier environment. Initial carrier trials for the F-35C are scheduled for 2013. The F-35C is undergoing test and evaluation at NAS Patuxent River before delivery to the fleet." |

| It seems to have shut off its AB almost immediately after takeoff. Is that normal for other jets using the catapult? |

| It depends on the load and flying conditions. There are many times when it will not use AB at all. |
