Thanks for your honest reply...
I will leave it here because we would be off topic
Tejas and jf17 are projects with different set of goals
Tejas was for india to gain experience in manfacturing after it already did multiple JV and underlisence projects
While jf17 was PAC first attempt for anything (PAC only built saab propellar and parts for k8)
Also jf17 was meant for mass production and was a safe design
Tejas unfortunately suffered from bad design(lack of canrads) this will be rectified with mk2 but mk2 is essentially a new aircraft
Tejas was never liked by IAF even now it is reluctant buy, but jf17 is something PAF is pretty much satisfied with..
Jf17 was suppose to be minimilistic ..every move was made to cut the cost, a dual seater was therefore never planned, fly by wire was selective and design was conservative
Only later PAC saw potent of jf17 and interest, it then scrabled to build a twin seater.
It also decided to make it a 4.5 th fighter beyond the standarad order of 150AC. the changes were made possible by incredible advances in china
With full FBW, a new solid engine with thrust equivalent to ge414(rd93ma), an AESA radar, jf 17 will surely find alot of sucess
Tejas scrapped the canrads and decreased the length of aircraft a bad design move that hunts DRDO/HAL till now.
When it comes to export market, tejas mk1 will not be brought by anyone its flawed design. Tejas mk2 is what tejas should have been(see gripen, same engine)
