Fuse 13
Beagle/Wander00 et al.
My recollection is that the accident where the fin came off was due to rolling in the vertical with g still applied rather than intentional use of rudder.
That said Boscombe did issue a clearance certainly in '77 for a 'twinkle' with fuse 13 removed and the limits were:
1.360 degrees roll max
2.MIN 330 kt (to limit aoa therefore sideslip?) (I'm a bit hazy on the exact speed)
3. 1g
How many other jets do you know with a min speed for application of full aileron?
It looked pretty good but needed a bit of spacing as the jet moved about 10 ft right and 10ft down.
Hope this helps
