The only CG problems I've ever had was with Nitroplanes stuff. Go check your forums. Many of your customers say the CG on many of your products are incorrect. I've put together 10 ARFs. Not one ever had CG problems, except for the two that came from your store. Yes, two other ones from your store flew fine. Like I said earlier, many of your products are good. But some are just not worth buying, especially if the CG is wrong. Go read the forums. I'm not alone.
