The corsair is a great looking plane👍The master series definitely looks like the FT guys make it look easier than it really is for most people though. I may experiment with a couple techniques on some small rounded components on my builds using their style of curving,but don't see myself getting too into those techniques any time soon. I'm just starting to get good at A folds and design better fuselages using more basic methods. I agree somewhat with the sentiment of others, FT should develop a build and fly difficulty rating for all their planes. When I was new and saw the Nutball they sort of touted it as a beginner plane, and it definitely is for building, but flying,it's at least an intermediate level.
This is from the master corsair
This is the simple scout
I not saying they are on all, but I think they have a rating on each plan I have used
