Mikoyan-Gurevich MiG-21 Fishbed U-model Update (Part 6a). This was the trap of using two computers during this project; I forgot to make sure the xml compilation file was the same in both computers. This update fixes the Romanian LanceR-B and Croatian UMD models from my part 6 package; so that the rear canopy actually closes now; and also fixed one little config file entry error I discovered while testing the model fix. Simply copy and overwrite the original package installation, which is required (mpai_mig21_ai_traffic_06.zip), and available on AVSIM and AVSIM.rus. Models by Michael Pearson.
