Hi friends, I know this is a bit of a "hairy" thread, but would like to throw my own 2 cents in here.
First off, I love the 4.11 patch and can't wait for Modact and HSFX to start supporting it. And a big thank you to Team D for continuing to to support their game, I bought every version and expansion at release and it's money well spent.
On topic, I think there is something slightly wonky about the F4U-1x's that bears investigation. I've been monkeying around with carrier takeoffs, both on the shorter CVEs and the bigger Essex CV's, and it's been a nightmare. I can't take off on the CVE to save my life, stationary or moving, ordinance or none. Fiddled with the missions a bit using the FMB and still no luck. I tried just about every suggestion in this thread that I could find but no joy.
I saw someone's comment about a book mentioning that "All US naval aircraft could take off fully loaded from a stationary aircraft carrier", so I started doing a bit of digging myself. I found this information here:
http://www.wwiiaircraftperformance.org/f4u/f4u.html which appears to reference a number of official publishings from the manufacturers and military testing. It just says the -1 version and not which subvariant. Regardless, the data on take-off distances vs. fuel load is interesting. "Overload" which appears to be full fuel t/o dist with no wind is 660ish ft, 100 over the length of the Casablanca class CVE's in game. 15 kt headwind is pushing it, 25 kt is faster than the CVEs can go but adding headwind to make up for it can be done. I still couldn't take off with a combined 25 kt Wind Over Deck with full fuel as indicated by that source. With a 310ish ft t/o distance the F4U should pretty much leap off the deck, like we see in some of the Youtube videos posted.
As a few others point out, there are some interim solutions that can put a bandaid on this in the mean time, but I would submit to TD that this does bear some investigation.
