WOW!

 

Thanks for you hard work!

[NoreZi 179]

Maybe shown mass include both mass of ammunition and belt itself ? As I know 20mm rounds weights 100grams each, multiplied by 350 rounds ammo itself can weight approx 35kg !

[s9723 508]

Maybe 90kg means rough mass of mg151 + ammunition?

Not likely:

1. not all have same number of rounds.

2. MG151/15 round weighs a bit less, but in game same 90kg

3. as ammo used the weight will change.

 

As it is, to number may just be a text, does nothing to FM.

Hello there, I edited some incorrect photos. 

I don't know about flight model, but i do they take weapon weight in account. but I am sure the gun pods data reflect a change in the Flight Model.

 

[Pony51 6,545]

We will see.

[Pony51 6,545]

You forgot the Do 17Z-7 and Ju 88C-6, added them to list.

Hello thanks for the remind, the Do 17 Z-7 was added to the original post list. while the Ju 88C-6 was not,because i don't  find it to have mg151/15 or mg 151/20

 

New screenshot with incorrect information of the mg151/20 added:

Do 17 Z-7

Could you add Ki-61-I hei to the list, too?

Do 17 Z-7

 

 

Ohhh, yes, the 88c-6 is incorrect.  It should have 1x 151.  for a different report.

Will do!

 

I think it is a universal value.  Set one, all will change.

 

...That the only Japanese plane with 151?

I think that Ki-61-I hei is the only Japanese aircraft equipped with MG 151/20 in the game and in history.
The German aircraft purchased by Japan for research is an exception.

[Ingram IV 162]

Hello there, thanks *tester188 for the additional info, I added the Ki-61-I hei to the original post. , that info also shows the correct weight of the weapon.

Also I would like to ask ¿should the AMX-50 Foch be included in the list? it has the mg151/15 as a secondary gun. but I don't know why it does not show the mass/weight value.
