Updated, everyone, a lot of things have been updated. You can tell by the number of parts. The update instructions are as follows:///////////1* The automatic guns on the side are improved into "Dark Cloud" anti-aircraft guns, which are distributed randomly to a certain extent, and the upgraded fire control system improves the hit rate! Also more improvements! ///////////////2* Replace the bottom main gun with a semi-hidden machine gun turret with laser aiming and shell throwing effect. The switch is "Activate1" Automatic aiming and injury firing rate are well controlled. //////////////////3* Four tracks have been added, and now you can run on the ground without mod! Switches are "LandingGear".And this is also the button to switch the flight mode. The speed control switch of the wheel is "Trim".Pulling up is accelerating, pulling down is decelerating, and turning left and right is "Roll"./////////////////////4* Now, we have mastered the automatic hovering technology. When in air mode, "Trim" Pull up to fly up, pull down to descend, hover without moving, fully automatic. /////////////////////5 * has added an automatic landing system. Now, when you switch to land mode directly at high altitude, you don't have to worry about breaking, because when you are close enough to the ground, the buffer engine will be turned on to assist landing, and the final descent speed will be about 12 kilometers per hour. Very convenient and safe. ///////////////6* modified the position of speed brake, which is more beautiful. VTOL opens when it is lowered. //////////////////////7* Modify the appearance, which looks better. ///////////////////8* removed the transition system, because it encountered some problems that can't be solved by the current technical force, and may rejoin in the future.//////////////9* improves the principle of attitude control engine, and it is not easy to get out of control and slip when turning.
