This is very welcome since it is one of a handful of U.S. Navy airplanes that have gone unrepresented as an injection molded kit. A built model looks pretty good:
It's clear that the length of the nose-gear strut on this model is representative of the TF-9J on display at the Pima Air&Space Museum in Tucson, Arizona rather than a flyable airplane. (It may have been fixed in the kits as produced.) The "sit" should be more like this:
There are few other detail discrepancies notable in the model built. See http://tailhooktopics.blogspot.com/2014/06/grumman-f8f-8ttf-9j-notes.html for some notes and illustrations. Darren Roberts is providing a excellent and informative progressive build review here: http://www.arcforums.com/forums/air/index.php?showtopic=277195&st=0 and a summary of the build here: http://www.zone-five.net/showthread.php?p=286534#post286534 Before you buy it and for sure before you build one, you should take a look at his posts.
Another very helpful and illustrated build review: http://www.themodellingnews.com/2014/07/review-build-nic-cougar-tamer-takes-on.html. Note that the builder did not encounter the problem with gluing the plastic that the kit is made from but did note a couple of detail errors. (Others have noted the "Marines" marking on the upper right wing is incorrect; it should be the aircraft number and the tail code.)
One configuration option provided in the kit is the ejection seat. The first two-seat Cougars were delivered with Grumman ejection seats. These were soon replaced with Martin-Baker seats. See http://thanlont.blogspot.com/2011/02/transition-to-martin-baker-ejection.html. The Grumman seats were used in the model above, but Martin-Baker seats had been standard long before the Marines began to use the TF-9J as a Fast FAC (Forward Air Control) as the model is marked.
As usual, the single best reference on a Navy airplane is available from Steve Ginter. See http://www.ginterbooks.com/NAVAL/NF68.htm
Darren Tamanaha put some excellent detail pictures of the Pima TF-9J HERE. Note that the shock struts are bottomed instead of being inflated as it was for a flyable airplane.
