Well it's armed with two HJ-10s, which is in line with predator and is as good as anything else or better on sale on the open market.
I think FT-3 might be a bit heavy. FT-5 or the 50/100kg LS-6 variants should be doable.
We know CH-3 can carry a pair of FT-5, and it's a good deal smaller than pterodactyl
To be fair they didn't quite need F-16E/F either; their mirages were serving them fine and they could've been like anyone else and gone for F-16Cs instead. These rich ME countries usually want the best for the military (and can usually afford it), I suppose they had a tender for a MALE uav and CAC won it. The capability to fire weapons may or may not have been a requirement, but if it wasn't it certainly won't have hurt the chinese offering. I don't think heron and eitan can fire weapons, yes?
Anyway, do the flags on the tail look like UAE's, or is it just me
