In reality B-5713 does have a split winglet, but in the game not (picture 1)and after I change the option.tmc file(picture 2), the split winglet actually be painted, so I think developers may forget to rename the option.tmc file,
Although this may only be a very small problem, for the sake of reality, I think it can be fixed before the official version is launched.(don’t forget to change the preview.ttx)
Thanks again for the 737-800 and so many fantastic liveries
