Default Hey Dudley, detailed analysis of these?

The best technique to use in low altitude roll entries is to use adverse
yaw to your advantage as you enter the roll. You need top rudder anyway
and that's the way the nose will go if you don't use rolling rudder into
the roll to coordinate the entry. I just allow the yaw and follow it
closely with top rudder as the roll stabilizes.

A lot of these guys doing low altitude rolls will use inside rudder with
aileron entering the roll because it's the "natural" thing to do. If the
rudder isn't switched immediately to opposite rudder as the roll
initiates, this will naturally be bottom rudder and pull the nose down.
At low altitude, this can get you killed.



OK, that's the way I always did it. Rudder into roll until the adverse yaw
is no longer a problem at say about 30 deg. Swiftly to top rudder then. I
found, in most of the draggy things I flew, that if you didn;t, you lost
the point. With the roll rates I'd be dealing with a large aileron input
was required (max aileron, to get even a 2.5 to 3 second roll) and adverse
yaw could be fierce. rudder required was only light though and I was fully
mindful of the consequences of not getting top rudder in quickly! I'm
having trouble remembering how I did a lot of things though since at the
end of the day I just kept the point in place and did the neccesary to keep
it there. I'll have to re-educate myself procedurally, though.
