A classic film, which I inspired me and I suspect a lot more, to join the RAF.

Red Arrows shot Kemble?
98% of it, yes! Seems a few snips edited in such as low level over rough moorland-type ground and and even a shot of Valley(?) but the vast majority at Kemble. :ok:
Was actually standing on the old Reds pan just a couple of months ago with a friend who works at Kemble - talk about memories of better days (late 1970's) now long gone! :sad:
Ho hum!

Farell,
Perfect timing. I had been looking for pictures of “twinkle rolls” and there they are at 7:00.
I love the jazz-flute music - so evocative of 1960s documentaries and cinema ads. :)
Ah yes, Pearl & Dean......

This is also a very evocative film from the Reds Gnat era.
Brings back lots of memories.

Is the 2nd Seaking "02" in the background the one that crashed in Indonesia in 2005?

That roll rate just has to be seen to be believed.
What a fabulous little jet it was.

The Reds Gnats had modifications to the ailerons to enhance the rate of roll, I believe it achieved 420deg second :E

Fuse 13. An electrical circuit limited aileron deflexion at higher speeds; with fuse 13 removed full aileron was available which increased the roll rate significantly - although it was more than sufficient with the fuse intact!

Ahhh - thank you.
V. interesting.
Lovely video...what a safe but boring world we live in now!

The CB to restrict the roll rate was there for a purpose. Excessive roll rate can cause what is called "roll/yaw diversion". This will happen at high speed at low level (lots of air for the ailerons to work on!) Effectively the aircraft starts tumbling. Of course at high speed the aircraft will break up. This happened in front of the CinC when he was watching the years approval of the that year's display pilot (no names, no pack drill). The arrows pulled their C/Bs and got away with it. I suspect because they never flew at warp factor nine when thay were rolling. I was involved with the aftermath.

Roll-yaw coupling was the recognized term

I'm no TP but I remember alpha being significant. Grey matter excused, the limits on a 'twinkle' were 300-350 kts, S & L, 360 deg only.
The break up referred to earlier to DL was I believe during a vertical roll after a 6g pull up.

I imagine it must have been a little uncomfortable physiologically rotating about an axis so quickly?
Aside from the eyeballs comment - during a twinkle roll was there any sense of red-out?
Trying to imagine the vectors - surely even with a g-suit, a little blood would travel headwards...?

Watched the John Noakes Red Arrows video, does a C130 still accompany the Reds around the UK?
Fuse 13. An electrical circuit limited aileron deflexion at higher speeds; with fuse 13 removed full aileron was available which increased the roll rate significantly - although it was more than sufficient with the fuse intact!
Yup that was it, they just pulled the fuse LOL

Tartar, No ‘G’ involved. (it was all over very quickly) Just had to brief pax to brace or helmets would thump the canopy. On reflection I think that the min speed may have been 350? long time ago

....it’s a long time ago but seem to recall a stiff neck due to forcing head back in anticipation was an occupational hazard!
