according to a guy who has seen J-10 take off, he said experience J-10 pilots can take off in 10 planes length (< 200 m). And I don't think J-10 has a more fragile airframe than FC-1. Of course, they would have to do some serious modifications first, but I think J-10 can take off from a stobar carrier.That's news to me. But I would still pick the FC-1 since you can always find a better engine and J-10s can't land with shock.
