Are you talking about the electric vortex?
Yes. It's Exceed's version but it's the same thing.
I'm running some 4600 packs. It does it no matter which batteries I use. It's not terrible, it's just noticable. Either I've never noticed with my other R/C's or it's just a trait of this one. I have about 35 other cars and trucks.
