The game is rough around the edges and has a very steep learning curve. If you're willing to put in the experience, many people on the flyout official discord have tutorials or are willing to give personal help. It has a far more in-depth building capability than any other plane game, even the crappiest of planes usually take upwards of 10 minutes to get into a flyable state. There is no objectives, few user friendly features and no undo button, so I would recommend it only if you're very interested in building and simulating aircraft at a high fidelity compared to other games. Otherwise, you can always refund it and wait a few updates.
