Practice, and only Practice will make you perfect

Had a look a the video, Firstly, superb flying. few things that i thought needs a look see :-
(a) i think little more throttle manipulation is required, KE at slighlty low speeds would have looked cool, for the KE lead with the rudder, that slight nose drop could be avoided, the danger of leading with the rudder is the pitch variation that you need to cater, so what i do is i get into KE before i turn off on finals (most displays pilots do that), this way you have sort of masked the variations if any.

(b) Was it 'Avalanche' at 2:16, if it was, Flick/Snap needed to be little more deliberate, my Snap  is little different from conventional, it really looks cool, instead to same side aileron rudder i go the opposite side, it kills the speed slightly, but looks real cool, try it and let me know.

(c) your point rolls are good try a 4/8 point rolls.

(d) i thought you could use a little more expo at high throw, in fact what i do is i commence my wall at low to mid throw, thereafter change over to Hover throw (Which is slightly less that max throw, which i use for Rolling Harriers), advantage is that little bucking at the wall is avoided

I dint plan this flight at all it was all random manuevers. .. I know dats bad.. Smiley.  I think it was 3-4rth flight on this plane.. . I had just learnt turn arounds at time so i was mostly focusing on that.. Yea that knife edge entry looked terrible.. Will keep that in mind next time..
At 2:16 it was snap roll with oppsite rudder n aileron in tailwind.... But i dint give enuff elevator to semi stall the plan.. I shud have given more of elevator..  it wud have looked more neater.. I used to do snaps the same way as you told but during a conversation with a championship pilot i was told its not considered as a legitimate snap.. Snap shud b ailerons n rudder in same direction.. But its diffcult to end a snap neatly if we do it the correct way.. Tongue timing of rudder n aileron EXIT of controls in the snap matters to end it at wing leveled  or desired position.. Still working on that..
The plane had no mixing in this flight. . Only 40% expo on ailerons n 30% on elevator n 20 % on rudder at full deflection.. 
Avalanche is at 2:33..
Still long way to go sir. . Will surely come up with a better planned routine next time.. N greasy landing. .Coz some judge only by landing.. Wink

It is different for every aeroplane, and entirely depends on cross coupling and roll acceleration value, and surprisingly different at different wind speeds. Head wind exit is faster than tail wind
