Per manual, these settings give you a range. Beginner-3.5", intermediate-4.0", advanced-4.5". It will be very forgiving, self-correcting with the beginner CG...intermediate, a little less so...if you are a newbie you'd better be on your toes for the advanced CG though. I like to set this plane up with no dead weight so its CG is at the advanced position. Then add weight to the front to do the beginner's CG to start with. Once a pilot gets confident with that, take some of the weight out. Then once the pilot is doing even better, take all of the weight out and let 'er rip!
