F-35 and Airshows
the Canadian performance was posted a few pages back.

Sorry, if already commented on.
IF the aircraft departs at such a high airspeed at that time we are all in trouble - head for them thar hills yonder....

They need to come up with a snappy name for what's becoming the F35 signature move.
I believe that is called J turn

I have seen the bobble in other videos, it just looks abnormal. Maybe not departing, but a hiccup.

How do you know it isn't just the pilot letting off backpressure to reduce AoA?

Salute!
Yes, Mars, likely FLCS control laws re: pitch or roll rates.
And as Spurts observes, pilots still matter.
Could also just be pilot easing off the controls if he didn’t like rates.
The VooDoo I flew a hundred years ago had a stick pusher that moved the stick forward using 28 pounds or s and normally would jerk the stick outta your hand. It activated on both pitch rate and AoA.
Viper rate limiters were very obvious.

I first noticed it in Flynn's PAS routine, it almost looked like he was being sloppy with the maneuvers at first, such that he had to put in corrections. But I seem to recall someone noting that the F-35's FCS is designed such that it flies on rails, precisely going where the VVI is pointing, so I wouldn't be surprised if the aircraft is just making a rapid "fishtail" to cancel out any residual rate and arrive at optimal AoA as quickly as it can when exiting a maneuver.
I personally think the "bumps" make the F-35's demos look crisp compared to other aircraft.
SO the first Canadian video was his practice flight, the P-51 hadn't arrived yet and he was basically just out practicing maneuvers getting his airspace down.
here is the same camera guy and the full demo

(1:22) DAMN son. That little slide there at 2:55 is pretty sweet too.
