So after flying with any given angle on the chopper under full throttle, lowering your nose slows you down for a second.

Take off. get some speed. Level to 0 degrees and suddenly lower your nose by 10 degrees. You will see your speed drop. This can also be done by flying at 10 degrees nose down and lowering by another 10. The chopper will slow down.
Pointing the nose up actually speeds you up for a bit.
Pointing the nose down slows you down.
No, that's not how it works. When you lower chopper nose, drag is increased, but the forward-looking component of the rotor thrust is also increased. Hence, you will only accelerate.
(I'm a physics major, and worked on Rise of Flight aerodynamics with some guys formerly from Eagle Dynamics... So I know what I'm talking about.)
It is strange, if you takeoff in the AH-9 to a few hundred feet and than point the nose straight down with rudder and a turning cyclic (to keep you pointing down and spinning) you wont loose much altitude... just spin around in a tight circle :D
Pointing the nose down in a helicopter causes both drag and forward-pushing force.
BUT, before it starts moving, the helicopter tends to move it's moving vector towards the ground.
This is more noticeble when flying at a steady speed in leveled flight (for an example let's use 100 Km/h);
if you drop down your nose and increase your collective (to don't loose altitude) you're applying 2 forces:
Nose down = vector pointing towards the ground at 100 Km/h, angle depends on how much you pitch down (also causes drag force to increase, exposing more surface to the air you're flying trough)
Collective up = vector pointing towards the sky at a 90° angle from the previous one.
This causes to move forward in a helicopter maintaining a leveled flight, but also has a "dead time" in the middle because of those forces "fighting" each other.
I Hope what i described makes sense, english is not my native language.
Edit: in the above explaination, i have intentionally omitted the intertia force from the previous leveled flight to keep things simple
"Makes sence. But why would pointing nose up increase speed?"
I'm no physics major, but I'd think when you lift the nose up a bit from a steady 'slightly-nose-down' forward-movement, the chopper loses drag and gains more lift, making it 'lighter' which in turn causes a slight increase in speed. But what do I know..
Now, this is the main problem of democracy. Everyone has their "opinions" even if the right answer is right in front of them on a table. And of course, every person's opinion on physics is as valuable as a physicist's one. So yeah, keep rolling.

It should not, it's a same kind of bug.
