<DIV><FONT face=Arial size=2>We often think that the wing is producing zero
effect when we go K.E., but the AOA of the wing is still positive to the
datum line and as long as we have forward movement of the airframe a force
will be generated away from the gear. That's why you have down elevator
mixed to rudder in order to nullify this effect. I hear many people state
that in K.E. the wing is not producing any lift, but it sure is reacting to
the airflow and decalage.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For the K.E. Snap the airframe still needs to
be in a stalled condition and it's still elevator that's necessary to
produce the effect of the stall. Due to the visual perspective the
increased AOA required to stall the wing will be undectable to the pilot as
well as the judges because in K.E. the pitch-up will take place
horizontally instead of vertically.</FONT></DIV>

further seem to me that this input must, by it's very nature produce a
pitching attitude to the fuselage whether positive or negative. So I
would have to conclude that the attitude "break" referenced by the rule

<DIV><BR></DIV>Jim,<BR><BR>I have no clue how you think all three axes
can be initiated at the same time.
You keep forgetting the part of the RULE, quoted
verbatim below, that says the "fuselage break and
separation from the flight path" must happen "BEFORE THE ROTATION IS
STARTED". I'm NOT equating fueselage break to pitch break, it
could break in pitch and/or yaw, if it doesn't start rotation at
the same time. If you initiate all three axis at the same time,
rotation WILL start at the same instant, and that is
specifically NOT permitted. READ THE RULE! The judge
MUST determine if the fuselage broke and separated from the flight
path first, BEFORE the rotation started. If it didn't, he
MUST severely downgrade.<BR><BR><BR>

correct, as long as there is no roll induced at the same

rudder alone will induce the "supposed to be in a stalled condition"
though!! There are many attitudes (e.g. 45 down on
center) where a judge could not likely see a rudder
departure alone first, and thus conclude that departure did
not occur before the roll departure started. And a judge
might also not see a pitch departure first on a end box
upline snap, but he could see rudder first. It is VERY clear
that simultaneous roll with either or both of the
other axes departures is NOT allowed as others have
tried to state here. I did say that pitch and yaw
departure could happen simutaneously, in my original post, as long as
roll doesn't occur at the same t ime.</SPAN></FONT></DIV>

thought the FAI changes explicitly allowed flick rolls? The
rule <BR>reads, "... fuselage attitude must show a definite
break and separation <BR>from the flight
path." <BR> <BR>It doe s not say, "MUST SHOW PITCH BREAK."
Please DO NOT ERROUNIOUSLY <BR>APPLY A PASS/FAIL MAJOR
DEDUCTION initial assessment to the snap roll. <BR>Watch the
whole maneuver then render your score. <BR> <BR>A break
and separation from the flight path simply means that the
nose <BR>and tail of the plane must rotate in a conical fashion
about the fight <BR>axis. Yaw, roll, and pitch can all break at
the same moment if that is <BR>how the pilot does
it. <BR> <BR>Hey :) some really handsome smart guy wrote
some stuff at this link <BR>below about snap rolls to help
clarify how they are done in IMAC. <BR> <BR><A
