As to your skid, I wouldn't attribute this to trim but rather to the
fact that it is almost impossible to line up "dead 6" on a target
you are over taking. If you are off to either side by just a few degrees
it is going to require a lot of compensation from rudder imput as you near
to firing range, d2-3. You didn't say in your post if you have rudders.
If not I recommend that you do get them and use them to produce enough yaw
to get your shots where they should be. If you do have them, don't get too
caught up in trimming everything perfectly on a pass. To be honest, I generally
trim my plane on time for level flight and all other adjustments are made
by either rudder of joystick imputs. If you are over taking a guy on a BZ
pass, you really shouldn't have time to mess with your alieron and rudder
trim as you approach him. Keep your eye on the target and dont think so
much about trim as you are going for the kill.

For the last 3-4 months or so, I've started trimming manually a lot,
so I can do it quite fast (A look on the slip indicator will tell me how
much is needed). As for trimming for speed, even if I trim for 250 mph,
it will need severe rudder/stick input when you reach 450, which I found
made it harder to hit the target. (And yes, I have pedals). I've noticed,
though, when I reach that speed, left rudder input have very little effect.
It crossed my mind after I posted yesterday, that I might be trimming in
crossed controls?!?!?.
Furthermore, I only experience this in the P47.

I'm not sure what you are refering to by crossed controls but it is odd
that you only notice this in a 47. At 450 ( which in a US plane like a 47
is MPH and basically hauling ass ) you won't get a great deal of movement
from stick and rudder input. Yes the 47 is an excellent plane as far as
resisting compression is concerned but at that speed any plane is going
to have diminished response from stick and rudder inputs with the exception
of the 262.

Crossed controls: If I remember right (I've only skimmed this part in
my flying training book), you can keep a plane in balance with opposite
stick & rudder..(I think this only refers to when flying in crosswind..I'm
sure some of the other guys out there can correct me on this..otherwise
I'll check when I get back from work)..but if that's the case, I could imagine
the same thing was happening, due to slipstream/torque effect...ie the plane
is in balance, but in effect skidding due to the torque/slipstream.

Daff,
I have not had this problem with gunnery (I fly mostly the FW, 109, Corsair,
Mustang), but you might try programming a button on your stick or throttle
as the "autopilot/angle", and then engage it for a moment
when you're pointed right at your intended victim. I use this sort of trim
shortcut when I'm on a Jabo run, and find it helps me line up.
