Hello, @Yurakap5. Welcome to the site. Please read the rules and follow them, so you won’t get into trouble.

Yes, this is indeed your first plane, and a lot of flaws come by. The entire plane is unusually chrome, too many weapons, the wings looks odd, the fuselage and nose cone looks odd, the cockpit fuselage is missing (you could have used fuselage slicing), and there is indeed no throttle or trim control (and yaw pedals). Try to improve your skills. If you don’t know how to do it, try to figure it out by yourself, and if you still did not, get help from other people (and make sure you follow the aforementioned rules and try and be patient, don’t throw tantrums if you didn’t get help). Enjoy the privilege of using this site.
