Buying a 1-35 pros and cons?

The problem is that flaps are digital, they are either on or off, unlike
the analogue nature of spoilers...

Not to be dogpiling this issue, but Bob (the other Bob) is right, and
Dave is way off base here. Really, I have to wonder where ideas like
that come from.

With only a little bit of practice, it is possible and practical to
modulate flap extension through the entire range from full negative to
full positive, and I have in fact done that very thing pretty
regularly.

The key thing to understand is that using large-span flaps takes what
I call "feed forward." If you change the flap setting and then wait
for feedback from the instruments and from your senses about your
speed and angle of attack, you will end up way behind the airplane. If
you wait for feedback, you'll end up stuck in a feedback loop.
Instead, you use feed-forward. As you deploy the flaps, you apply
forward pressure on the stick at the same time. As you retract the
flaps, you apply rearward pressure. You can adjust the amount of
pressure later based on sensory input; but any pressure change in the
right direction is way better than none at all.

Even though I am developing a glider with conventional airbrakes, I
would make one with landing flaps if I thought I could sell them that
way. Flaps give the very best bang for the buck in glidepath control,
and I miss the safety and security they always afforded me.
