I have never stated that the 109 isnt forgiving... yes, it is! But an other thing, it turns around in 19 seconds, on a 550 yards circle, while the spit8 does it in 15.5 seconds, on a 430 yards circle...
The K4 is very capable, yet very hard to fly really well - to take advantage of its great post-stall abilities. I have only seen a very few, maybe a dozen pilots flying this plane to its full potential. In the other hand, some folks just use the raw speed and climb rate: the K4 turns into an easy mode pick-n-run beast, only limited by the compression. I dont like that kind of flying.
Back in the day, when i was flying G6s, and was trying to learn the proper usage of the post-stall moves, a very decent pilot called me to the DA and was choosing Spit16s. I have never been flying that aircraft before that and was amazed, how ridiculously easily it went nose-up, did the tailslide-hammerhead and went nose-up again. True, that aircraft wont tolerate the rapage on the controls like a G6, but surely felt much easyer to fly. The spit8/9 with their longer wings were a bit different though, but those moves werent impossible, after 2-3 tries, i could pull them just the same as in the 109. Again, they wont tolerate the very extreme control inputs like the 109, but arent nearly as horrible as Bruv is trying to tell.
For the spit14: its very close to the K4, but a bit slower, a bit better climber, turns clearly better but on a larger radius, and now, this spit is really unstable.
For Bruv: is that the D9's flight what you demonstrated in the TOC/koth? Nope, good sir, i refuse that kind of flying. There are enough from those ponies, 190s, lalas, 109s, mjugs, even a couple spits too out there, no need for one more 190 flying that way.
Give me a valid reason to stop hating, please, and i will do it instantly and happily.
