I need to reaffirm you with what Ariana said.
Don’t give up on your Skyvan. Treat it as a piece of art, as a labor of love. Improve your techniques and skills by applying them to her first and don’t feel discouraged. There is an improvement project for Carenados 182RG, so I can only guess you could start improving the Inibuilds SC7 on that end and again learn skills for yourself to apply in other projects.
Supplemental:
Look at the Porter by FlightSimGames. Announced in April 2021, overtaken by Milviz with their release in September 2021, again by Asobo with their offering as part of 40th anniversary edition in November 2022. They are still working on it and plan to release in the fall this year.
