    Nice models, Roberto! Those are good 'weathering effects' on the SIA-9B.

    Hmmm... No line drawings of the 9B online. No stats for it in the Unofficial stats, either.

    This is the SIA 7B:

    Stats for it are: H Maneuver deck, -/B, 11 Damage, 14 Altitude and 5 Climb rate. The 9B would be faster, with its bigger engine, and perhaps a better climb rate?

    Seems the types were retired to training fairly quickly, the SIA 9 was the 7B2 with a bigger lump up front, the extra weight looks to have kept the speed to within 5kph of its predecessor so stats likely to be the same perhaps.

    Even more great Italian Front aircraft.
    Keep them coming Roberto.

    I looked at the nearly 400hp difference between models, and thought there would be a substantial increase in performance. The 300-ish pound weight increase to a 1500 pound plane was too much, it seems, if all they got was 5 kph speed increase.

    So, the same stats as the 7b seems appropriate.

    The stats I have put the SIA7b at 186-200kph but the SIA 9b at 214kph. Climb to 3000m (~10000ft) in 14:00 for the 7b but 12:00 for the 9b. (See the Wings of Linen WIKI).

    Roberto, I'm not aware of anyone making SIA 9b miniatures (and only Shapeways for the 7b). Could you point me to your source so I can add them to the WIKI?

    Happened a fair bit. The attempt to re-engine the Bristol Fighter with the Liberty 12 (400hp) proved a colossal failure. Much better was the Liberty 12 in the Dh-4 and Dh-9A.

    So, how close is the FIAT R.2 to the SIA 9b?

    Could I use this drawing for the 9b?

    It would be closer to use a SIA 7b with a longer nose and curved exhaust pipes. I'll check and see if I have any 9b drawings this evening.

    The Fiat R.2, by the way, is another of those overlooked planes that deserves a Shapeways model. Some day...

    The Hansa-Brandenburg W.18 and the SIA 9B are models made with 3D printing by a my friend.
    The images of the SIA 9B and the cards we made.
