This is a crazy experiment that I'm not entirely sure of what I am doing so if anyone knows how to fix any issues there might be, please do. I would greatly appreciate it.
Anyways, what lead to this project was that I noticed that at least three of Air India Express' and one of SAS' 737-800s don't have any winglets. I decided to try see if I can modify GabrielYV's 737-800 to have optional winglets. Then I thought why don't I take it further and expand it to include the other members of the 737 Next Generation family since I see 737-700s and 737-900s that fly by my house that I wish I could do liveries for but can't because the only 737 Next Generation add-on I know of for FlightGear has models that have issues (engines to shiny, liveries won't show up on the winglets...). Anyways, long story short, I more-or less combined GabrielYV's 737-800 and said 737 Next Generation add-on to make this. Like I said earlier, if anyone knows how to fix any issues there might be, please do.
