[WWII] P-47D Thunderbolt

[Kale]

From a modern perspective, isn't this sort of like the A-10? Rugged more so then well armored? Like HANS says, a high HT to roll against seems to make the most sense.

88 it is then. Didn't found the formula before.

My reasoning was based in the 3e stats, to get eWeight I had to use the formula Lwt - Payload, according to the Lwt and Payload definitions on WWII p.100:

P-51 is 4t - 0.7t = 3.3t (WWII p.110)

P-47 is 6.9t - 1.6t = 5.3t (Dogfaces p.83)

So a increase of 60% in mass should mean a similar increase in Hit points. But it seems I missed something, or the 3e stats where wrong.

Basic page 558.

But now I got that the P-51 should have 74 hit points! All my searchs point that the empty weight of the mustang is around 3.3 tons. 3e stats agree with that.

High tech assigns 84 hit points, in the errata for the book this isn't changed. This was a typo, the hit points derive from something beyond empty weight, or the empty weight of the plane is for some reason different of what WWII and the sites I consulted say it was?

If the empty weight of a P-51D was 7,635 lbs then I get a ST/HP of 79 . This may be errata for High-Tech. HANS?

I have two print sources showing 7,125 lbs unloaded.

Since HP are based on the cube root of mass, 1.6x mass should have 1.6^(1/3)x HP. That's only about a 17% increase.

Ignore everything after this. It's been pointed out that I was going by incorrect memory of the rules.

Also, 4e vehicle HP are based on normal loaded weight, not empty weight (I guess it's assumed that the frame is designed to handle the weight of normal stores without a problem)*. 84 HP is in line with weight of about 4.5 tons, which isn't out of line with numbers I've seen for the P-51.

* For realism, you might want to base HP on a lower weight for vehicles that are "overloaded" (edit: and possibly lower HT). The Panzer I mounting a sIG 33 comes to mind.

How's that help? That gives a lower value (77). BTW which sources?

What's your source?

EDIT: Basic 558 uses empty weight.

I was simply explaining how I got my previous, uninformed, figures. Didn't arrived at the cuberoot formula until Sir pudding pointed it to me...

If this is the case, the P-47 should have 107 hit points, figured from the 9.7 tons figure from loaded weight. And the P-51 should have 91 hit points from his loaded weight of 6t from High Tech. The numbers don't match again. I'll wait for clarification on this.

Basic 558 says "4x(cube root of empty weight in lbs) for Unliving objects" (emphasis mine). I'm not sure where Ryan's getting the idea that it should be loaded weight from. Either this is errata or HANS used a source that gives an empty weight of 9,261 lbs for the P-51D.
