Everyone thinks mine is modded.It just screams.I hope they don't change it.I like it just the way it is.When these two are worn out (soon) I'll buy a couple more.I am not sponsored by these guys either.I just know a good deal when I see one.....No engine in this price range is better than the Caster Grenade...Period.
