People have already estimated the size of the J-20 using a support truck parked next to it. Its size is about 20 meters long. How did you estimate the J-20’s size? I hope it’s not based on superimposing images of two planes that share 0 common parts, because you can easily do that with any two planes.

If you don’t mind I will come to tell you why esitmating size via that truck is unaccurate and that will be massive deviasion.
First, perspective angle to be considered is impossible, not even estimate it.
2nd, included angle generated by truck and that aircraft was not considered, not even estimated also.
These two angles are being there certainly and if the error caused by those go to conversly direction, then we get lucky, but if the directions they went to are same, the the deviasion will be tremendously huge.
Naturely, the deviasion could be middle between to extrems of them, so the 20 looked is not an unbelievable data, but with nothing fixed.

However, as one can see, what I done is set limit from two sides, and to eliminate those impossible region, then we get a reckonable interval.
The diameter of engine which amounted on J-20 larger than D30F formed impossible region at right side, and left quadrant is limited between zero to the diameter of engine which MiG-29, JAS-39 alike equiped.

It is not hard to find an upview photo of Gripen to coincide with same angled MiG-31. If you compress that J-20 pic ratio equalled to Gripen or Rafale, what a funny it will be?
Besides, there is a photo showed a group of people stand around J-20 in which focul point is that main wheel with several people aside so we can see excatly the height of that wheel really is almost taller than a man’s hip, same at least. It is a huge jetfighter since Tu-128 and Yak-250.

anyone can resize the J-20 to fit the size of another fighter. I can resize the J-20 so it looks closer to the Gripen’s size.

you need something in common to base the size on.
i.e. Pak-fa vs Flanker comparisons are done using the front tires as a reference point.

Notice your missiles are supposed to be carried internally and your nozzle shouldn’t be a water needle alike, my baby……！

guys, i found some interesting stuff:
a new stealth jet concept design, submitted by Hongdu Aviation Industry (Group) Corporation, China

Don’t post too many wet dream here, the layout obviously is unreasonable if you learned some aerodynamics.

To benhongh:
Even with long-coupled canards, the wing recieved washing from canards still strongly, enough to promote lift. You can see it by a pic of wind-tunnel testing of EAP which uploaded many times in this forum.
The layout of VLT, the J-20 used is pretty unusual.

I deem there is a litle difference between enthusiast and amature. :p
To kick those “half yuan party” ass should be your mission…

In terms of my conjecture, the EF is the most unstable fighter ever built, with regard to static margin, F-22 and Rafale will come close, say about 30%, then next is Su-35 around 20% which proved by Chinese literatrue.
Back to F-22 and Rafale, I even suspect that negtive static margin of Rafale is greater than F-22, notice that canards of Rafale deflected angle tremedously downwards during subsonic level flight.

I can only assume it’s something like F-18 E/F’s blocker, however no one knows untill T-50-2 comes out right?
Or you have already got an idea of what does it look like?

How does it demeged faster speed more than that “bump” then?
Notice what the original post was:

Thankyou for your input. I don’t get alot of time to study these things so thought it’d be quicker just asking.
I’d think that if the TWR of the T-50 is similar to this bird then this J-20 will be the faster of the two………..

Ohh yeah? Non obstructed!
What that bump would be then?
