Neg Kieran, we were not vulching, just maintaining 15k and attacking any enemy trying to get out of his field ack. The rook nikki arrived at low alt, almost lower than us and after a lot of unsuccessful attacks of the higher 190. We were not trying to get alt advantage over than 190, we were simply ingnoring it and easily evading it when in his dives. He knows that if he want to deffend his lowers mates his only chance was to slow down and fight and he did that at the time our nikki was near the base just to be HOed by a quick reversal or the nikki. A higher SpitIX, probably, would had much more success in the defense of his lower mates.
Basically, what I mean is that if D9 want to be untouchable, it will be, but will be as untouchable as ineficient. If you want to be eficient with a D9, then you'll be very very touchable. In my case, I need a very good position and a range of 250 yards of less to be able to put a solid burst in the enemy. With hispanos, a single lucky 700 yards ping is a sure critical damage, spray a bit, pray a bit and work done.
A last point, this is my perception that D9 has much worse control at hi speeds than anyother 190 version, as well as slower roll rate. I'm rarely able to follow a diving spit, not due trim problems but due very violent vibrations while keeping similar speed than the Spit in a long dive.
60/7 vs SpitIX? Then I want it perked cause I'm bored of killing it
Seriously, we actually have almost 1 spit of every 4 fighters (counting only fighter deaths). The reason of that overusage is not just that spit is easy to fly for newbies. Zeke, Hurri, C202 and 109F are also extremely easy to fly (all of them marginally used). The main reason is that Spit is a deadly plane, a very efficient one for our kind of arena, IMO, much more efficient than D9 will be the monster that historically was while spits IX and V will be just mediocre planes.
