This is a bit basic but since it startled me in during an unusually gust
departure, I thought I'd mention it.
The flaperons (early model IV) are dramatically less effective in roll
control when in full flap mode. Most folks learn this early on and then I
bet primarily use flaps just for minor trim adjustments
I almost never use my flap lever except for minor in flight trim
adjustments. I'm the only person who flies my plane And the plane is
almost always hangered when not flying. So I (WRONGLY) expect the flaps to
be set where I leave them.
However the plane was out one night when a front with strong winds came
thru. The winds pushed the flaps into the full down position which I am
embarassed to say I did not notice.
The next morning when I went for a flight in very gusty post frontal
passage conditions the plane required so much stick input, as I broke
ground that I thought something was badly wrong. For an instant I was
about to abort the take-off before the brain kicked in and I reached down
to adjust the flap handle.
Nothing was broken except my preflight technique. The friction on the flap
handle is tighter now to help prevent movement when tied down and I'm a
bit more attentive during prefilght.

Guys,
Great to hear that the pilot was not to seriously injured. I will be very
interested in hearing what the cause of the incident was if they are ever
able to determine it. I have heard of a somewhat similar incident in which
the pilot of a Kitffox was not able to roll ailerons to one side after
takeoff (He said he had full control movement before takeoff) and decided
to
make an off field landing. He said they were unable to determine what
caused
the restricted controls condition during the post incident investigation.
