I don't get it, sorry.
Because why would they ever build an aircraft with removable CFT's and then not ever remove them?
I assume, they wouldn't be called CFTs if they had been modeled together with the rest of the airframe and if so they would not be removable then.
No offence. Of course i could be very very wrong with my opinion, because I'm not an expert, just a hobby-aviator and a DCS-enthusiast.:smilewink:
