I think adding a new tournament might be a good idea so everyone who sees the ad might be pretty excited to compete besides others. Introducing splicing to parts is a really good idea but it might be a little too complex for new players.
maybe having the sizes/rise and run on one part and having smoothing and splicing under "advanced settings" would really help all the new players that will be coming.

I think the tutorial is outdated its mostly just blocks and i don't think it needs to go but I think it should be a 2 part tutorial where the second one requires some fuselage wore and more advanced wing work.

let me know if you agree.
