I owned a flew a Speed Astir for many years. It was
my first glass ship after gaining about 40 hours in
rental glass ships. The Speed is a natural transition
from the Grob 103 to the Grob 102 and then the Speed
Astir (Grob G104). I got more compliments on how good
it looked than anyone. I had no bad habits and you
can fly it with flaps set at 0 degrees until you are
comfortable in the cockpit. I agree with the other
comment that AFTER YOU ARE COMFORTABLE with the controls,
the takeoff is a bit more solid by starting with negative
flaps and dialing in 0 degrees once you have airleron
control.

The Speed is an easy ship to fly with flaps because
it is set up so that once you trim the ship to 60 knots
at 0 degrees flaps, you can make all speed changes
from 40 knots to 100 knots by just changing the flap
setting. Full plus flaps gives you thermalling at
40 knots and full negative gives you 100 knots. That
is, if you have the CG set at 75-80 aft in the fully
loaded configuration.

The only negative I had with the ship was the heavy
airleron forces on the stick due to the hingeless control
surface design.
