Thanks for the compliments, much appreciated.
Now what did I stick my fingers in this time... Yep, another not-so-funny chore:

As I had already cut off the rudder for the resin replacement, I sort of had to go forth with the rest of them, and the ailerons turned out tricky.
Simple as cut-off-styrene - glue-in-resin? Not quite, I'm afraid. All that styrene cutting would have been best to do with the wing halves still separate. Now it was an excercise in patience and eye-hand coordination. First I needed to remove the styrene aileron. Somewhat simple, although the wing edges weren't at the same level. That was followed by some tedious carving, trimming and shaving.
Then it was time for... you guessed it, more trimming! Now with the resin part. I had to file the back edge of the aileron to compensate for the lack of the rounded groove in the wing (which could have been done, had the halves been separate) and cut a notch to mount it.
When I was done with that and the resin part fit was ok, I noticed there was a unsightly gap in the underside. Solution: styrene strip and superglue.
Now it looks sort of okay when dryfitted.


I'll still have to do some more slight trimming and sanding (the aileron still extends a bit beyond the trailing edge), re-building the outer edge a bit with superglue, but the major work is done.
Yes! I'm done! ...Halfway through. One side done, one more to go.
Moral of the story: Some preplanning isn't necessarily a bad thing to do.
