For carrier ops, I recommend Dino's T-45, or his F-14. He says they both work in P3D v4, except some of the sounds, and the airborne refueling system. There is a quirk with that which will refuel non-existent external fuel tanks. He recommends not using the airborne refueling system at all until he has time to fix it. He also says that until they get caught up to P3Dv4, TACPAC is completely non-functional.
Other than those little details, his planes work great. The STOVL system in his F-35 doesn't work either, but he is working on it. He says that when Mr. Dowson's FSUIPC is updated for P3Dv4 it should be restored, using the alternate STOVL gauge included in the F-35 package. I recommend reading his notes on all this.
Personally, I love the F-14, but, being a trainer, the T-45 is easier to land on a carrier. It has a small problem with the plane's length to it's tail-hook. Apparently the carrier's IFLOLS and ILS set-ups are all tuned for the F/A-18. The T-45, being a shorter aircraft, if you follow the ILS and IFLOLS, will tend to land a bit long. You will get a 4-wire trap vice a 3-wire, or a bolter. You can fly a little under the indicated glideslope, however, and catch the 3-wire. Again, remember to have the correct AOA and speed for the plane you're using to get a good trap.
The frequency for Javier's Nimitz v2 is 115.00, if you need it. In FSX, the default carrier frequency is 114.00. These are ONLY for the HUD included in Dino's and the FSDT plane's. This frequency assignment is for that HUD to display the ILS needles, and guidance to the carrier. It's internal to the HUD, and has no existence in the "real" world, IE: Other plane's HUD's or NAV radios.
I believe those frequencies are also valid for the RFN gauges as well, but I don't use the RFN stuff, so I can't say for sure. I have heard they work pretty well with P3D, but I don't know.
Have fun! I sure do
