Considering the utter mess the tejas program is, I agree with you.Great finding.
Even our original designers don't know on what Tejas is based upon. LOL
Oddly all Russian fighters operated by India prior to the Su-30 had short leg issues. Even the Mig-29 needed fuel tanks with the UPG.Tejas is short legged. Russians don't believe and operate short legged fighters else they would have built one already.
