Hi guys, all Aries jets have this sound in the air. It is given by the construction of the airframe. Be very careful and check everything carefully and secure all screws with loctite. My friend's exhaust pipe came loose during the flight. Aries began to burn in the air. It was completely destroyed after the impact. When everything is in order, it flies very nicely. If you want to use 3D acrobatics, I recommend a turbine with a pull of min. 300N. ***winter***
