the hs55 do buzz brand new out of the box. i just plugged them in the receiver not attached to anything and they buzz. not too bad and they go away and come back. no big deal because they are performing well at this point. they'll probably strip easy with even the lightest of crashes. no big deal there either because they're only 10 bucks. i got six ready to rock and roll.!. so yeah i'm gonna bring it with the titan.
