Default About forward slips

I presume that if I do it correctly, then, there should be no change
in the actual direction of motion of the aircraft, but only a change
in its orientation in the air, right? I haven't achieved that thus
far.

So if I'm going straight in and I do a forward flip, I should be able
to look off to the left out the window and see the runway approaching
me (or to the right, although that might be harder from the left
seat).... [Ref. the video]... I gather that you were actually looking
sideways down at the runway, and not in the direction the axle-mounted
camera was looking?


Yep. Here's another video that should answer most of the above questions:

Note that the aircraft attitude stays fairly flat. The tail mounting of the
camera does exaggerate the amount of offset, as you can see that my head doesn't
have to move all that much to keep tracking the touchdown point.

The Fly Baby model on MSFS can't, but I always figured that was
my fault. :-)


Or you had automatic rudder coordination turned on (it's the default).


Considering I designed the Fly Baby MSFS model, it's my fault either way. :-)

Actually, the problem is more the limited throw of the yaw control. The Fly
Baby has a very powerful rudder, but the pedals have a fairly long travel. That
makes it easy to input the precise amount of yaw. On the computer, the stick
only wiggles ~10 degrees left and right. I can run the rudder scalars up on the
MSFS config file, but then the rudder control gets too sensitive for normal
operations. Even a set of rudder pedals (older Thrustmasters) didn't give
enough control throw.

BTW, for those who are interested in seeing the complete videos:

....uses the external camera positions and

has the shots from the ground plus a little air-to-air. As a side note, look
how much the rudder moves to keep the plane tracking straight as the tail
touches down. Would require some SERIOUS wriggling on a computer control
stick....
