There is a tendency for R/E models to pitch up when a turn is
initiated due to gyroscopic precession.
Yes. But this precession effect is very very weak. In my simulation
of a BD being given a fast 30 degree rudder input, the nose pitches up
by only 0.03 degrees.
Nevertheless, in this

I can see this effect on a moderate sized glider where the plane has
inertia, however what happens when using a DLG?
I am trying to understand the observations we see when a light plane
is used. A DLG appears to be nearly at it's stall speed when
rudder deflection is added. Hence from a
When a rudder stalls due to AoA deflection, what would a pilot see?
Is there less rudder response?
I'm not sure what the original poster (Jay Hunter) meant by rudder stall.
It was either
1) deflecting the rudder causes the glider to stall, or
2) the rudder itself stalls.
Effect 1) can

This note is to add one point to the discussion on rudder-elevator
flying.
There is a tendency for R/E models to pitch up when a turn is
initiated due to gyroscopic precession. The rudder initiates a yaw
rate, giving a yaw angle. This angle couples with the wing's
dihedral angle to

Would it do any good to rake the rudder hinge line forward to counteract this?

Rudder stalls this is where I found the concept. In the
building instructions of the photon II there is mention of having too
much deflection, and having too much deflection may 'stall the rudder'.

Hi Jay,
I have been flying my Photon 1 in the IHLGF for 4 years. I have
a Watson tailgroup on it (Spyderfoam/FG) which is close to the type the
Photon II has. I use alot of rudder throwand use the rudder
for tight thermals, as well as using it for drag breaking and
stalling. You have to use the
Chris,
That is VERY enlightening. I had just discovered I needed my
elevator in my turns once I have the ship banked. I think I am
going to return my rudder to my right stick. It will make flying
it easier. And when I fly the aileron ships I will move it to the
left side.
Thanks again..

Ok, I have received a few answers, I want to thank everyone for the
answers... Amazing all this time and I have never understood how the
rudder is supposed to work
