This civil aviation aircraft is very good.Quality stands up to inspection. It's a good choice for carrying passengers. Landing instructions for take-off aircraft:1.The plane doesn't have to add throttle when it lands on the Isle of Wight. The same is true in other corners. If you think you've slipped to the top, Then please pull the trim up to the full. 2.When the aircraft takes off and flies, it is recommended to control the throttle between 25% and 27%,There is no need to refuel during the period. Specific introduction:ag1&ag5:Lights,ag2&ag3:Simulate horizontal tail shedding and vertical tail shedding. (If you don't want to simulate a crash, don't touch these two buttons. )Two bombs are a small rocket:Simulated fuel tank explosion and air disintegration. (Same as above).Thank you for choosing Z-151-100. Wish you has a wonderful experience.
