Now I‘m again confused … #5307 clearly has fins and this is the YJ-83K traNing round, however #5309 - the one without fins - is a KD-88 “lacking fins and other features“. Or am I confuse something again?
KD-88 = fins with antennae
KD-88 training round = no fins or tails or other details compared to real KD-88
YJ-83K = fins without antennae
YJ-83K training round = looks virtually identical to real YJ-83K, except with some removed details like a blunt air intake etc
sndef888 was asking how we can differentiate a YJ-83K from KD-88
I was explaining the differences between YJ-83K and KD-88 -- but also pointing out that your image of the J-10 with the KD-88 (5309) is a training round and is not what a real KD-88 looks like, and doesn't include the key differentiating features between YJ-83K and KD-88 (the antennae on the fins).
On the other hand, the picture in 5307 shows a YJ-83K training round yes, but it is also accurately representative of what the real YJ-83K looks like in terms of key details.
