I have downloaded the «Mig-21um Panel» (file name: 12821_panelMiG21UM.zip) and the other file that is needed («Su-15 panel with gauges and update for Mig-19 panel»), but how can I «install» the MiG cockpit into an aircraft? (Like Captain Sim’s MiG-21UM)

I copied the panel.cfg into the existing panel.cfg for the Captain Sims Mig-21UM. I launc the game, start flying the MiG but the cockpit bitmap is black. So agen: Instruments are all visible but the cockpit frame is black…

what should I do?

Am I missing something? A file? Or something else?

Please some one help me!

Thank you!

(sorry my bad english…)
