Perry just as a matter of interest please try a forward slip at high altitude and
tell us what happens. For example is the canard stable or
does it buck in yaw or pitch? I am curious. The C 172 with full
flaps pitch bucks a little bit in a forward slip.

All Cessna's that I've flown do this..  I think you'll find that most [if
not all] Cessna singles [ other than the 208 which I've not flown] are not
approved for slip's w/ full flaps. I used to get into a divergently
unstable pitch situation all the time w/ a 182 when flying skydivers..  it
was controllable when you were expecting it.. when you weren't [ the first
few times it happened] it got your heart pumping..  Mind you.. these where
Max rudder on a straight tail 182, w/ enough bank to keep the heading
straight and then forward pitch until you reached Vfe and hold it there..
w/ about 17inch MAP.  Used to go from 2000 asl to 12000 and back to
2000[surface] in 18 minutes.. The other way to do it was Vne and no flaps
and 17"MAP..  but in the summer bump's you'd lose sight of the wing tip's
during the bumps.. not a really secure feeling.. We got paid by the trip so
the faster the better.. :-) 27 trips in 1 day was enough to wear ya out

Why do you think they are not approved for slips Jarrett?
Was it the pitch buck or was it some other reason?

I have always known that but it does not bother me to do them
anyway in my angled tail 182. As far as I can tell it does not
pitch buck like a 172. Maybe I am doing them wrong :)

Of course you can run out of gas as all the gas tends to
flow to the lower wing when the tank selector is on both.
But then again you are landing usually so you should not care
if the engine quits. Never the less I set the selector to the
upper wing. There is a scenario where someone may pull out on
the runway at the last minute.
