my father and i are baffled we have a fancy c.g balancer and my father is trying to balance his great planes dazzler but its doing soething really funny that none of the other planes have ever done..it appears to be totally backwards when we add wait to the tail instead of the tail dropping the tail rises and when we add weight to the nose instead of the nose dropping the nose goes up and the tail goes down. it appears to be entirley backwards and we can not figure it out as to why. it appears to be defying physics and we are stuck cratching out heads at this we have tried balancing the plane both right side up and upside down and teh effect is the same and we are balancing on the recommended c.g point. if anyone could explain to us as to why this is doing what it is please inform us, as we can not figure it out

thank you!
