Yes, it seems that this is a simply built airplane, but I actually improved the original version for forth times and here is the latest one. I love creating aircrafts with fewer parts (100 - 500) and better flying performance (No ridiculous XML modification), and this one I believe is the best aircraft I have ever made.

Above are superfluous words, some useful imformation is below:
real P/W ratio: 1.1;
empty weight: 14.6t;
fuel weight: 3.6t (4577L, enough for a nomal flight misson, but if using afterburner, pay attention to fuel capability) ;
weapon weight: 9t;
AG1: arresting hook;
AG2: release most A-to-G weapon;
AG6: stable mode;
AG7: afterburner (add 30 more tons power);
By the way, strongly advise you to put the Su27-HUB at the xyz-position of ( 0.0000, 5.6884, 7.5030 ).
Wow, that's all! ! Thank you for your appreciate~~
I've got to say it is amazingly friendly to air-carrier pilots, you can drive it to practise your air-carrier landing skills.
