Nevermind my last post, found my answer in a search. Apparently AE overlooked the 3 pivot CVD system like the Losi CVD's have. According to a discription on another thread, the two pivot design of the CVD's causes the CVD to accellerate and decellerate 4 times in 1 revolution causing the chatter. I haven't noticed much decrease in handling but was just wondering if others are also experiencing this. Might be an upgrade part for AE to look into.........
