The Trumpy -4 isn't terrible, but its not perfect in a few areas that may or may not be of concern. The cockpit needs a replacement and thankfully there have been sets available in the past. The landing gear bay openings have some minor shape issues, and are missing a lot of details internally, the gear and wheels and tires could stand replacements, the tires in particular are made of an artificial rubber/vinyl material and not very convincing.
To most people built out of the box, it's obviously a Corsair and with 4 blades and the other subtle differences, more knowledgeable folks would know it's possibly a - 4 and the anal retentive subject matter experts will tell you all about how 90% of the kit doesnt look anything like a Corsair.
I found the 1D that I built from Trumpeter a great warm up to more complex kits back in its day, and the dash 4 even more fun. Just remember, one guys idea of fun is possibly not yours The detailing that you need to do to bring either Trumpeter kit to exceptional quality can be done with some pretty involved scratch building and a lot of patience if you need a mini carbon copy... Or consider purchasing aftermarket items as one sees a need for. If you arent absolutely married to the idea of your Corsair having to be a -4, I can HIGHLY recommend ANY of the Tamiya Corsairs, the 1A and 1D look great in RNZAF markings. that would be an exceptional choice right from the box, you would just need to source some decals and seatbelts, maybe some .010 fine wire like micro solder or lead or copper for engine wiring if you like detailing engines. In 1/32 you have a lot more room to add if you so chose.
All the best with your project whatever you chose.
