i don't know exact speeds, till i go home and look at film.....midwar. 38j comes into a27 high. i was climbing through 4k grabbing hard trying to get up to him. two others rolled. i saw him make a pass at the base, going for the dar. i followed, but couldn't catch him. saw him extending and pulling up, so i went vertical.
watched him turn, and i was already positioned between him and the base, a few thousand yards off to the side. as i see him enter the dive, i start my turn, coming out on his six, d1,000, and closing. he didn't re-climb this time, but rather kept going at tree top level.
i was holding at d800 now. zoomed in, i'd fire with just guns, and if i saw hits score, i'd put some cannon rounds out there. it took me a bit of chasing, but i got him.
it's not that hard to get a faster plane, if you're in the right place at the right time.
