I believe J-10AY is the designation for the J-10s which are part of the august 1st aerobatic team?
The only physical differences is the addition of wing smoke pods, and the paint scheme I think.
... and the scale is 1/48 and not 1/35 !
this is kind of interesting. It looks like we have two J-10s number 60288 and 60289 (maybe I'm seeing incorrectly?) at CAC.
If this is so, then it seems like they are sending more J-10s to FTTC.
