    DB 605 vs Merlin

    I personally prefer DB 605 over Merlin in single engine application. With DB 605, you can put arnament (MG and Cannon in the spinner) in the nose, provided the plane design had enough space. That is enough for air supremacy one. Putting DB 605 in Bf 110 was a waste of time. While Merlin, in my...
  3. What does M Ratio and S Ratio mean in the RAF pilot's notes?

    In the pilot's notes for both the Hurricane (AP1564B) and Spitfire (AP1565E) there is no mention of what M and S ratio actually pertains to. There is no explanation I could find in pilot's notes general (AP2095 ) either. Any help in understanding exactly what this setting is would be greatly...

    Hi guys, some of you might now I'm doing a CAD model of the V-1650-7. I have several copies of the Illustrated Parts Manual for it but unfortunately they have been revised post war (1947 and 1949). Because Continental took up production late and post war they made some changes to the Bill of...

    Spitfire cruising settings

    Hi all, Its been a while, but I'm back after being insanely busy with work for about 12 months. While I've got a little more spare time, I'm working on a long-ish piece on the realistic(-ish) possibilities for a long-range Spitfire emerging in 1941-1942. With that in mind, does anyone...

    Anybody know climbrate of Spitfire Mkii w/ Merlin XII?

    Just wondering if anybody knows climbrate, either chart or in text, or a Spitfire Mkii with a Merlin XII engine. I'd be happy with climb and speed charts but if all someone has is climb that is OK by me, so long as its relatively specific for altitudes up to atleast 6km ideally higher
  9. Single and 2-Stage Merlin Pics

    I said I'd get some pics of the single and 2-stage Merlins that are sitting on stands at the museum, and here they are. The V-1650-7 is going in one our P-51Ds and the Merlin 224 will go back into the Ha.1112 when the restoration is completed. The 224 will have to be looked at since it...
