mine arrived last week and yes there was and update sheet in the kit as far as cg...it basically said that this plane will fly without any problems with a cg between 4 to 6 inches behind leading edge.....for you guys running the magnum...i don't want to down anyone or any manufacturer for trying....but when it comes to anything RC, after being in this hobby for 25 years and owning a local hobby shop here...that 90% of the the things you buy are on the saying "you get what you paid for".....for example when GP came out with the 1/4 giles i bought one and after looking at the servo torque required and the prices of the ones available...i went with the hobbicos and let me tell you yes they definetely have the torque...but that is it....it takes them an infinety to find center compared to the JR digitals and the slop around center we don't need to go there.....any how i can go on and on over crap i have been through in this hobby....how many of you know that Hobbico is actually the "main" owner ship of Tower Hobbies via Great Planes, Futaba and recently bought and owns Dubro...hmmmm this could turn into a wal-mart deal....point is why would the head name put there name on the cheaper products....hmmmm..
