Hi.

I read this topic a while ago, but have looked into it in the last half hour or so. Yes! You can do it.

In the 727 ACE, under Aircraft type, look for 727-100 another company Freighter. I had both the DHL and KFC freighters listed as another company. Neither one was showing up with the Wingtips. I checked (placed a "tick") in Winglets for the DHL and saved. It now has the Wingtips. It must be saved BEFORE you move to the next variant or model!

This also applies to the 727-200 Freighter.

Happy flying.

Mark

EDIT: I did this a couple of times and now they are listed

KFC -> 727-100 Freighter.
DHL -> 727-100 another company Freighter.
