Trajectory of MG151/20 vs Hispano Mk V

[STEELE]

I'm wondering why the HIspano Mk V has such a flat trajectory vs the MG151/20?
Everything I read puts the Mg151 at 960 m/s velocity, and the Hispano V at 840-880 tops!
Anyone know the answer?  (or is there one?)

There are two different MG 151

We have the  20mm MG 151/20, MV about 810 m/s.
960m/s is the earlier version, the MG 151/15

Cause Allied bullets are over modeled

OK
 if U'r right, that means the Mk V is only 30m/s faster than the mg151, so should fire just as flat
(810 vs 840 m/s)    
also the tempest barrels dont even stick out of the wing, so I'm guessing they are shorter than 190A8 mg151 barrels, which would cause the Luft cannon to be more accurate/flatter trajectory

Is that muzzle velocity for all shell types in the MG151/20 ammo belt?

You have to take projectile mass into account. Heavier bullet. Do not only compare speeds, better compare muzzle energy.

Wrong guess.

No, just for the fast but lighter mine shell.

Per Tony Williams in Flying Guns:

Hispano Mk II, HE/130g: 850-880m/s
Hispano Mk V, HE/130g: 820-850m/s
MG151/20, HEI or AP/115g: 710m/s
MG151/20, HE/92g: 800m/s (M-Geschoss (92g))
MG151/20, HE/105g: 640m/s (M-Geschoss (105g))
MG151/20, I/106: 745m/s

Pay attention to the 20x82 vs 20x110.

someone has been listening to Schlowy too much on squad channel me thinks.   

[Citabria]

if your bad fly a spitfire. (schlowy?)

if you know how to close to point blank range before firing or can eyeball extreme deflection shots then fly a plane that takes more to fly well than the spitfire, ie anything with bad balistics or low rate of fire or small ammo clip.

[RTHolmes]

FYI we dont have any spitfires with Mk.V hispanos.

where did I say that?  

Rather than improve their shot  (i.e suns, grizz) they talk about how unfair the model is.

I find the German weaponry devastating in this game when utilised in the correct manner.

Just as a side note, I very much prefer the German guns in the 109 over the Spitfire's simply because of the way they are installed. Nose mounted cannon & MG's allow me to achieve more with less ammo. If you have a good aim, it's often more efficient.

How correct you are.  Only the Tempest in AH has the Hispanos Mk V, all other UK or US 20mm are the Mk II/M2 variant.  They are only slightly less damaging than the Hispanos Mk II, hardly worth mentioning (Mk II = 4.03 lbs and Mk V = 4 lb.  I have not noticed any difference in the trajectory either, there is only a %3 difference in velocity and muzzle energy.

FYI: The Hispano Mk V did have a shorter barrel than the Mk II version.  The Mk V also had a higher rate of fire at a slight reduction in velocity (%3).
