Yes, Now we are very optimistic about this fighter. Aerodynamic improvements shall make this aircraft very fast with high acceleration and speed. 800 KG weight reduction will improve T/W ratio by 15%. Now we have reached to a stage where we can foresee our bird something comparable to gripen. a complete aircraft. Believe me , the way focused on light weight is going to be an asset in future, If we can make a comparable aircraft with say 700 kg to 1 ton less weight than we are the winners. Porkis mustebat for a long time that they inducted junk fighter ahead of tejas, but in all this days they are unable to improve any performance of aircraft. Junk fighter is almost the same as it was few years ago.
