<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Lately I’ve been practicing the IMAC Advanced sequence
as there are 4+ contests I can easily get to in SoFla that do not interfere
with the pattern contests I can get too. This has been a lot of fun to do and
a very good experience as far as flying aerobatics goes. I’ve flown
through the sequence about 40 times since November. This sequence has nearly
every combination of rolls, snaps, and a 3 roll 270 degree circle. One
observation about the precision aerobatics sequence is that you can nearly fly
the all of them rolling only one direction if you like. Rarely does a maneuver
mandate that you roll two directions in the same maneuver, let alone two
directions immediately after one another. In this one IMAC sequence you will
snap left and right, inside and out, 1 and 1.5 rotations, most followed by an
opposite roll or opposite point roll. There is also a negative spin and stall
turn. One vertical down line maneuver has opposite point rolls in it. Nearly
every maneuver must be tailored to the direction of flight as to ensure you end
up correctly. Most of the maneuvers offer a chance to zero if you loose
concentration or if your caller doesn’t quite get it right. After only a
few times through the sequence my left and right rolls became nearly identical
in quality (left side was always the weaker side as my precision aerobatic
sequence did not demand alternating rolling direction, I went with the most
comfortable direction).<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My favorite maneuver is the reverse avalanche from the top
with a ½ roll, opposite positive snap. While this maneuver on the pattern
forum received quite a bit of backlash in the Masters sequence (simplified as
the reverse avalanche with one positive snap), my 42% Extra 260 does it like
butter. One maneuver, the ½ outside loop with 1.5 snap, 8 point roll, is also
a fun way to end the sequence. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Without getting into a debate on the value of snaps, or the
judging criteria of snaps, or the snap versus flick-roll, flying so many snap
rolls over the last two months followed by opposite rolling combinations has
been incredibly good practice for all other areas of the flight. Doing these
in different wind direction and speed combinations quickly teaches how to vary
the inputs and a lot of other things. While it was obvious before, it is even
more obvious now to see how the “top-conpetitors” of the precision
aerobatic pilots are really capable in all the areas of R/C flight (at least
prop), IMAC, Pattern, and 3D. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>During this time I’ve also flown through the P07 FAI sequence
with the Extra (un-timed), and with my Aggressor with OS 140 and 18x10
Mejzlik. The stand out quality of the Extra is that is has slow downlines
built-in! The one maneuver where this is really nice is the square loop on
corner from the top with ½ rolls. The second leg doesn’t look rushed at
all. Also the hourglass with 2/4 down, second ½ looks nicer. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>All in all, this has been some of the best practice I’ve
ever done in terms or challenging you every flight in concentration &
finger-drills. Whether you want to fly IMAC or not, I highly encourage you to
practice some of these sequences. Some will say in pattern that you should not
move up a class until you have mastered the one you are in. I think that the
only way to solidly jump in skill is to challenge yourself with harder
sequences (plus it is fun). <o:p></o:p></span></font></p>
