I know they still make those larger "standard" sized servos for the giant scale crowd, but I haven't bought any since the 80's - I recently picked up a junk box at a swap meet included a handful of them and don't use them very often
Personally I think you'll be better off with the dual servo approach like you did, even though it'll require some arm trimming. Modern servos are much more powerful and reliable than back when this plane was designed, and with transmitters having plenty of channels these days you will have a lot more options for trimming and mixing via the radio with the dual setup.
