I think I'll do a narrated video about this move... but when I have time.
P47 requires rudder and flaps and 109's have to be slow and not use rudder, I'll post a film here shortly
WRONG and WRONG...
To start the manoeuver is very simple but its behavior is quite different depending on the plane, attitude and speed (usually lower than 225mph) but the jug can do it at 275mph.
Just yank the stick lower left with right rudder and keep it there until you need to recover or aim to shoot... or crash
Why?
1- Left aileron: The right wing giving more lift, it generates more drag and therefore induces right yaw on the plane (Try it with the Ta152 and see what I mean)
2- Pitch up: Pitching up is the key here as the prop gyro precession will yaw your plane to the right on a clockwise rotating prop (Try the WW1 Camel and see what I mean)
3- Right rudder: fairly obvious, the keywords being "right yaw" is all you need to hear. You can start by a left rudder and yank it right to have some more momentum (like before drifting a turn in rallye racing)
4- you DONT need flaps to start this manoeuver. Heck I can do it in the 190 below 200mph.
As you can see, every control input will help your plane tail slide to the right against the aerodynamic forces keeping your plane stable in flight.
When you master it, you can do it with 500' of ground clearance and find more uses to it like starting a LH spin in horizontal flight, a RH hammerhead or doing a "farewell shot" to someone right behind you.
On a side note, the Bf110 (and TA152) does the same thing but with left rudder and is almost unrecoverable (Its a simple LH snap roll). RH snap rolls on the 110 are very safe however.
