    WWII Fighter Combat Statistics

    Disagree strongly. Just as easy to lie or shade truth or make silly pronouncements, unfounded opinion, in a book as in a video. Greg, the subject of this debate, seems to me hold strong opinions but to base them on original source material, as much as possible. That's the way good academic...

    Did Northrop and Vought Help Design the Zero

    Maybe the best looking piece of machinery of any sort ever? My favorite, anyway. I knew Dick Palmer, who designed it, pretty well.

    Propeller Design

    Knew a flying priest who bellied a C-210 onto a snow covered strip. Jacked bird up. Sawed off the bent portions of the blades. Flew .5 hr. to shop. I was there. He said the 520 ran up to 3500 rpm at normal cruise speed. Head mechanic told him, "Father, you're gonna kill yourself." Flying friar...

    Propeller Design

    Thanks. Am just a dumb old pilot. Never heard efficiency at higher rpm was improved by more blades. More blades for sufficient blade area at high power and rpm, yes, but I always though for pure efficiency the fewer blades the better. More blades and/or wider blades were dictated by tip speeds...

    P-47 Load-out

    Suggest Greg's airplanes 8 part series on 47. Best youtubes BY FAR I've seen on 47, and there is a lot of info on what and how much they carried.

    About the Fw190 D9

    Go to Greg's Aircraft YouTube. View his 190 vids. The hole in the Jumo 190's spinner is explained in one of them.

    Groundhog Thread Part Deux - P-39 Fantasy and Fetish - The Never Ending Story (Mods take no responsibility for head against wall injuries sustained)

    Suggested reading on 39 I have NOT found in skimming this thread. 1) Nanette, Edwards Park. He flew 39s over New Guinea, went on to a long and distinguished career, part of it with the Smithsonian. Wrote very well. His book is full instances where the 39s were unable to engage because of poor...

    NACA Cowling?

    Could you provide details of how a "normal" NACA cowl, say what was used on C-47s and C-45s, would have had to be modified to achieve zero cooling drag? Thanks.

    Which country designed the best engines for WWII?

    Rotary? Come on. No Mazdas or Clergets in WWII.

    Spitfire Combat Radius (range) evolution, limitations?

    Does that mean B-17s-24s etc were fighters? They destroyed enemy e/a.

    Was the Vultee P-66 Vanguard really that bad?

    I remember seeing fly off comparison tests of P-66 and contemporaries. Cannot remember where. Think it happened at Wright-Pat, USAAC sponsored, but have no idea where I saw the data published. P-66 did OK v fighter with similar hp. I know Dick Palmer thought they'd given him a P-36 engine, and...

    Was the Vultee P-66 Vanguard really that bad?

    Nice depictions. Do you have details on P-66 engines? 1830 dash what? Were all P-66s equipped with the same HP P&Ws? Actual HP? Prop Ham Standard what? H-1 had a Twin Wasp Jr. 1535 dash what? 825 HP? The H1 as flown had more than the book value. Dick Palmer told me so. Among other things they...
