I had an interesting talk in Narromine last week with a local
instructor about my LS6. I bought it because I thought it to have few
vices.

He knew one.One that almost killed him.

Coming back after a racing task he selected +10 flaps, plenty enough
to land with, especially when it's a bit windy.
On final he pulled full airbrakes after gong through some lift on
base. This causes the flaps to come along, out +10 towards Landing
flap. This happens automatically. It only doesn't lock automatically
in that case. When about 20 feet of the deck he put half his airbrakes
away for a smooth landing.

So far, that is what I do as well.

Now the problems started. While putting the airbrakes away the flaps
slipped to negative. *Not very handy at 20 feet and relatively slow.
The glider promptly stalled.

He than did what he was thought by a test pilot." If everything goes
to ****, reverse the last thing you have done."

So contrary to what you would normally do when stalled, which is to
push the nose over , he pulled the brakes again, which in turn pulled
the flaps out again. He said that it saved his bacon. Took out the
undercarriage and hurt his back, but he walked away.

I've heard the Ventus 1 suffers from the same problem. Maybe some
other gliders as well. *I thought I should share it with you just in
case.

That's not supposed to happen in LS-6, as the flaps
are supposed to catch the detent. But it can happen.
There's some kind of spring that pulls the flap
handle towards the detent; sounds like that isn't
quite right in that particular glider. I owned a
couple of these gliders and always selected full
flap before using spoiler, which prevents this
possibility.

IIRC other gliders that retract flap with retracting
spoiler a
- early mosquito and mini-nimbus
- Calif A-21
Early Ventus does not have this problem IFF
proper flap detect is selected prior using
the spoilers.

Any others ?
Hope that helps someone out there,
