Post data collection comments, performance data, paint themes, and pictures here.

If necessary, I will break out responses categorically later.

I have a copy in PDF of

" F7F-1N, -2N, -3, -3N, & -4-N Pilot's Handbook (Revised)"

121 pages but a big size file, around 30 mgs but tons of useful detail photos and performance specs, If it's not too big I can upload it here if any interest or benefit

It is legal to upload the pdf? All of that would be great and much appreciated ... you can give it a try if no copyrights are violated in doing so.

I respect your concerns but this is a document published by the US government

"In the United States, U.S. Government works are covered by 17 USC § 105 (http://www.copyright.gov/title17/92chap1.html#105). "Copyright protection … is not available for any work of the United States Government, but the United States is not precluded from receiving and holding copyrights transferred to it by assignment, bequest, or otherwise." Exceptions are available for certain works of the National Institute for Standards and Technology (NIST) and the U.S. Postal Service. Copyright protection may be available for U.S. Government works outside the United States ( Section 3.1.6 (http://www.cendi.gov/publications/04-8copyright.html#316)). When a copyrighted work is transferred to the U.S. Government, the Government becomes the copyright owner and the work retains its copyright protection."

so I do not believe there should be any problem HTH

I can do the effects(flames,smoke) once you have a model(or exhaust port coordinates)

Interesting that as good as my 3-views are (or look), yours have more accurate cross-sections.

Thank you.

some info on flight dynamics

Excellent info Norab.

I also have some info on general handling characteristics from the book Report Of Joint Fighter Conference: NAS Patuxent River, MD 16-23 Oct. 1944 if anyone is interested.

It's somewhat subjective and it's in relation to an early F7F-1 flight tested there, before they made some improvements to its stability and control. The most interesting point being, that with an engine failure at military power, it required almost full aileron and full rudder to control the aircraft at 135 to 140 knots. Anything below that speed, forget it; In fact, one pilot said below 140 to 145 knots you're going into the ocean or the carrier's island. That was also worse case, with the left engine throttled all the way back and the right engine at military power.

It also reports that the F7F dives faster, climbs faster, and can turn with a P-38. But that the P-38 has better range and is better above 20K ft. Of course, to show the subjective nature of these reports, two different pilots that flew it during the test each fought it against the Hellcat. One bested the Hellcat and the other did not, which lead to some of their conclusions being different.

They all complained about the cockpit layout and the lack of rear visibility. But they all commented on what a great night fighter it would make, if they could just slow it down. I believe that is in reference for landing at night. They were somewhat prescient in that regard. ;)

They also said it would make a great fighter-bomber as it's visibility for strafing and attacking is excellent, although there was some distortion when looking down to the side through the canopy.

Of course, I might have to mess with my 3DSmax and the F7F when Milton is done and make a "what-if" bubble canopy USAAC day fighter variant, as a result. :)

The most striking comment on handling was that the Tigercat rolled faster with its rudder than with its ailerons.

Milton,
here's a link to the blog of John T. Sessions, who has just opened his collection to the public in a new facility at KPAE.

http://historicflight.org/hf/johns-next-flight/

At present there is no data on the site about the tigercat, but I know she's there.

as you see in the blog, he mentions recent repairs to the F7F. I can go up there easily from my place. If you wish I can contact him about photographing the cockpit --if you think that would be of value.

You may prefer to contact him directly, there is a phone and email addie on the website.

Let me know if I can be of further asistance, always a pleasure to help out MSA.

cheerio,
brady

Thank you Brady; that should be interesting.

Once we have made some progress on the mpdels, I am sure there will be voids in knowledge that maybe your camera and that F7F can answer. I appreciate your offer to get some pictures.

That is interesting stuff Sundog. I do hope you get involved with Fliger (Tom) with the flight testing too.

You can never have enough reference pictures for angular views, closeups, little features, openings ... all important and usually lacking. Thank you.
