It was done a couple of weeks ago in version 1.5. and I've got 4 more like it if you want to see them.
People are saying that Anacondas know how to match your moves. You just have to do the same to them. That's why it looks so easy in that video. The moment he starts to reverse, you must down-thrust. Occasionally, they boost up, which is no problem because it keeps you behind them. You can catch up and continue what you were doing. Whatever way he leans when at dome distance, you must go to his flank, so that he can't get a look at you. You just need good reactions a good HOTAS and good thrusters. I find all Anacondas the easiest ships to kill, not counting Pythons. Whatever algorithms are in their AI, they don't work against an FDL. I've been trying a Vulture today. The same techniques work, but it's not as easy as with a FDL.
The Anaconda in that video looks very docile indeed because it never fires back never uses chaff and a few times it manages to get some distance by boosting away but then doesn't do a boost-flip to face you. The Anacondas I encounter in CZs and RESs manoeuvre much more aggressively. They boost-flip to face me and hit me with their large fixed beams while flying backwards and then try to ram me when I try to get behind them again. And on top of that they have beam turrets that hit me almost uninterrupted because they ignore chaff. I can kill them nearly always before my shields drop but it is quite a struggle because of the low pitch rate of the FdL. Like you I use the good lateral acceleration of the FdL to make the difference.
