Literally just got this thing so just checking but...... Half throttle sounds fine like a normal r/c car and then if you floor it, it literally sounds like multiple swarms of killer bees. Like neighbor's dogs start barking. And that's on 4S. The Hobbytown where I picked it up checked the mesh out of the gate and said it was good to go so I haven't touched anything. It may as well be a nitro. Is this normal??
