content: Haha yes, you can hear it in the video in the link i posted above, here's the YT link directly. Much of the noise is due to high-rpm inside a plastic body. I remember always being jealous at someones plane, helicopter or car when I was younger, but now I finally have time and money to play(i'm 30 this year) , and nobody's stopping me, so far i've got a JR Propo 450 helicopter, Trainstar(plane with 1,4M wingspan), and this boat. I bought extra 4s batteries to this boat so i'll be able to reach 80 km/h in theory, i'll post again with video once I get out.
