I had no idea that trim can have such a big effect on speed

[jokash]

I knew it had some effect but that it can have an effect of Bf110E2 properly trimmed goes 460km/h at continuous power and about 440km/h if you fly at default trim and use the stick to level it.

Just remember that I did some 'Speed experiments' with the Me262 and experienced the same.  However - don't remember the exact numbers any more.

The rudder fine control is even more important in terms of speed. Step on the ball! (turn and slip indicator)

Mhmm … but not with straight line speed in a 2mot (? I think at least ?)

what's 2mot?

2mot is what German speakers call a twin engine aircraft.

And trim effects your aircraft no matter how many engines it has.  Planes like the P38 with handed props (they spin in opposite directions) will need less rudder trim, but trim still has an effect.

I would imagine that this effect is especially strong for aircraft with variable incidence stabilizers.
