i have no idea what you mean waffle, but im curious to find out....any chance you find that film post it

try this one out for yourself anyone.
SpitV, 50% fuel.
fly level at 220mph, a very slight climb, then hard right rudder, hard left aileron and hard back on the stick all together and very sharp.
as you spin past 100 degrees, hit full left rudder whilst keeping the ailerons the same and putting elevs in neutral possition. this should bring your nose round to 180degrees behind you. then spray and pray

after this, commence standard spin recovery. if you are good you can return to level flight losing very little E or altitude. (very gamey, sure its not possible in RL)
if you get it right the total time from level flight-180 turn-level flight can be as little as 3-4 seconds.
