I started these a while back. Some of you may have seen them on LSP. Three kits; two Revell N1K1-J and the Hasegawa N1K2-J. I have the Scratchbuilders Rex conversion for one of the Revell mid-wing Georges.
While the molding on the Revell kits is very nice (and subtle), it's raised. Complete rescribing is in order. Also, the Revell cockpits are very basic and there is no gear bay detail. I've used the Hasegawa pit as a starting point for the earlier birds. All three variants and different instrument panels. I bought three copies of the Brengun PE interior set for the Hasegawa kit. I've used some, but there was quite a bit of scratchbuilding along the way.
Resin inserts installed prior to cutting off the underwing cannon gondolas. I had to epoxy a piece of brass square stock to address a major warpage issue. Landing gear bay filled.
Lots of filling and sanding!
