su 27 "old"cockpit:
local FM = {self_ID, 'FC3', old = 3}
mount_vfs_texture_path("Bazar/World/textures/CockpitsHDTextures")
mount_vfs_texture_path(current_mod_path .. "/Cockpit/Resources/Model/Textures/SU-25-CPT-TEXTURES")
mount_vfs_model_path (current_mod_path.."/Cockpit/Resources/Model/Shape")
mount_vfs_liveries_path (current_mod_path .. "/Liveries")
make_flyable('L-39ZA', current_mod_path..'/Cockpit/KneeboardRight/', FM, current_mod_path..'/comm.lua')
it worked well, and we just need to change the ID
