Hello All,
I'd recently started helping to do some aircraft research for a Hearts of Iron IV (video game) mod called Ultra. Ultra's raison d'etre is providing a more historically accurate industry model, but it also aims to replace the base game's generic air units with nationally unique, more historically accurate ones. Since I'm likely to have to seek information on a lot of different aircraft over the course of my research I thought it would be best to make a single general thread rather then one for each specific type of plane.
In a lot of cases I will probably be asking for specific pieces of information that I find difficult to find though here's an overview of the specifications I have been asked to find in general (they will be entered into a formula that has been developed to determine the aircraft's in game stats).
Anyway the first aircraft I am interested in getting information on is the SM.79 Sparviero. I have a pretty complete set of specifications for early production 126 powered SM.79s thanks to the manual
sandokan
uploaded over in the technical section (though I do wonder if the range figures in that manual may be somewhat optimistic). But I'm less certain about later versions of the aircraft. I was reading that the Piaggo powered SM.79-II was more or less a propaganda myth and that only a single prototype with that engine fit existed. I was also sent some info indicating that SM.79s were modified with ethyl injection and eventually 128 series engines optimized for low altitude, but there doesn't seem to be a model designation associated with this aside from the bis upgrade which appears to largely be an amalgamation of various modifications that had already been used on existing torpedo bomber SM.79s. Going by what
Wurger
told me Series I, II, and III actually refers to production batches rather then specific engine fits.
Gathering the info I've received so far together, it sounds like the SM.79 did receive various upgrades including significant upgrades to the engines and fuel capacity, but there doesn't seem to have been much in the way of particular model designations associated with those upgrades until they were brought together as a factory conversion in the bis model. Does that seem more or less correct?
(Okay, I guess in the case of the SM.79 I'm starting off by trying to determine what the major Regia Aeronautica models actually were before I get too much into the specific specifications of the upgraded versions.)

- air to air weapons
- different possible bomb loadouts (if possible) with a preference for multiple smaller bombs over larger bombs
- max power to weight ratio at standard take off weight
- range of the aircraft*
- empty weight, number of engines
- is it designed as a ground attacker or armored (or both)
- wingspan + (is it a float- of biplane)
- maximum speed
- service ceiling
*I'm aware that range varies significantly with payload. Thus far I've been passing along load info when it is specified in conjunction with range.
