I just tried IF after quitting for a few months and I’ve noticed that the winglet is just a wing pointed up, it doesn’t move at all, only point up
? You mean with the wingflex too?
yup, wingflex really sucks in IF
That 757 is a ROCKET!!!
I hope they will fix it with A330
The 333 wingflex is pretty good
tried the a321?
Yup, took off about where A320s and 738s do
I’m disappointed… Proper wingflex is really important…
Then the 739? 
a centimeter from disaster (with flaps 10) 
You used full thrust or reduced for all the planes?
94% for 739, 93% for A321 and 752
Ok
Shows the 739 is really rubbish
I used flaps 5 for the 757
I have this app called IF Assistant, it gives me roughly the same speeds for A321 and 757, 739 V Speeds are usually higher
But the problem is, the 739 uses a crazy amount of time to accelerate and lift off
If you used 15 I can’t imagine how good it will be
XCub in windy days be like
30ft of RW
Verdict
757 - Exceeding expectations
A321 - Good
739 - Below standards
