I’ve noticed that, compared to other planes I see, mine kind of suck. I’m not sure as to what exactly I’m doing wrong but even my best plane of the few I’ve made (the best of which I’ve posted) is the F-23 Sky Samurai and even that isn’t very good. Any tips?
What FlightGuy said, there's no secret magic trick to "get good", you just slowly learn how to do things better over time. If you check the profiles of the highly skilled builders here you'll see the vast majority of them have been here for years, almost since the very beginning.
Same thing i said when i enter SP, yeah it sucks at the start, but you will be better over time
Most of the learning process for SimplePlanes is just slowly getting better over time. It may not sound very helpful, but that's just how it works: lot's of practice and gameplay.
Yes, you will probably use building techniques from others people's creations, but that will be a small portion compared to your own experience.
Give it time and practice, and your builds will gradually become better.
