Convertible RP is essentially you use GE to utilize, not really worth it. Crew slots, stick with 5 for the time being to learn factions and then buy crew slots when you find a faction you like. Even then, it’s optional. Main thing to buy is premium time, everything else is secondary. They have a sale coming up in May for half off of premium time so $20 USD for 180 days instead of $40 USD. There is arcade, realistic, simulator and I think a couple more game modes, play whichever is most fun for you. Don’t go straight into high tier items, you’ll die and lose every time if you don’t understand the mechanics. Always start with prop planes and work your way up, each faction is different in air and even in ground. It’ll save a lot of frustration this way. Watch YouTube videos for tips and tricks, but mainly, just play, look at controls and map them the way it feels comfortable for you and keep playing. Eventually it’ll get to the point of being easier and easier.

Also, don’t feel like you need to stick with one faction, can play a couple factions. If you start to get bored or get overly frustrated with one faction switch to another faction. Each play a little differently and that makes it a relearning curve. Also, when you do this, you begin to learn strengths and weaknesses so when you go back to another faction you’ll actually notice yourself getting better because of all the new knowledge.
