This Mikoyan Gurevich 21variant ( also known as the (Y)E-7PD) is a STOL version of the MiG-21 used in vietnam. This plane came about when the soviets wanted to test out the short take off capabilities and was only named the Mig-21PD after the trsting was finished. This aircraft is an experimental aircraft and has little information written about it that is easily accessed, but i have found some sources that seem to be reliable. The in hame model doesnt t have a forward mounted wngine like the real engine has but the inlet helps with the take off procedure... I have also tested that the STOL features does work by not using it, testing the stock model amd comparing take off length. This upload has added air breaks to slow down... But they are not needed at all. Please dont forget to rate and comment!
