 Hey Ed

Pete McLeod here

I'm fairly new to the aerobatic world (this was my first year, flew
sportsman in 5 contests, intermediate next year) but i've got a couple
tips for you

on the split-S : not sure where the acceleration is comming from, but
you'll want to make sure your not decending during the half roll...as
for the speed comming out the bottom...you should be able to controll
that with G, tighting up your radius will take car of any extra
speed...note: speed out the bottom will only help you for the half
loop up!

not sure were you are having you heading issues...all i suggest is
that if you fing yourself off heading NOT to correct right away (the
judges will see it) milk out the heading change in a radius. ex-if you
go off heading on the half roll on the split-s, pull through with no
correct and once you have pulled through the vertical and can see
where you want the nose to be, input rudder to move it there during
the pull out (keep wings level and a even radius). when you hit level
you should be on heading (and with any luck the judges didn't see a
thing!)

couple other things... don't worry about staying in the box, outs are
cheap in sportsman, focus on flying the figures well and flying them
in the right direction!

whenever possible fly with lots of energy (come into the box with some smash!)

have fun

hope some of this helps a bit

fly hard and good luck

Pete McLeod

I think I've got the 1 1/4 spin down good enough.  Thanks for all the tips.

The other thing I'm having trouble with is the 2 point roll at very
slow airspeeds.  I can roll OK at 120, and even at 100, but when I try
to roll at 80mph it gets ugly.  A few things I'm running into:

1.  I seem to routinely push neg 2Gs to get my nose up into correct
inverted pitch attitude (I'm flying a Decathlon, which has a
semi-symmetrical airfoil, and needs to be fairly nose high to for
level inverted flight path).  I shouldn't have to push much more than
1G, should I?

2.  Sometimes when I am approaching 1/4 around the roll, in knife edge
flight, and I apply heavy top rudder, the roll rate seems to slow or
almost stop for a moment.

3.  I'm still gaining about 20 to 30 mph on the half roll at the
beginning of the Split S, leading to some excess speed on the bottom. 
I try to pitch the nose up a bit to start the roll, but that seems to
make problem #2 worse.

4.  I'm coming off heading sometimes.  I think I know the cause of
this one.  I'm starting my push too soon, or holding it too long, as I
come around inverted.

Any and all tips appreciated.  Sorry if I'm boring you experienced
flyers.  I don't have access to a coach at the present time.

On the plus side, I did the Sportsman known at box alt today for the
first time, and bottomed out at 1800 AGL both times.  That made me
pretty happy.
