Question for you all, I ordered a Getterback for my Phantom after seeing some information on here and getting really nervous everytime I fly over water. I installed it on one of the legs yesterday (it weighs next to nothing) and flew the Phantom. It behaved really strangely. It would hover for a couple of seconds and then it would just fly sideways and backwards for a large distance without trying to correct. It would not stay in one spot for more than a couple of seconds before veering sideways. I landed the Phantom, shut it off, removed the Getterback, then flew it again. It hovered perfectly, not issues or weird behavior. So I am really confused because I know that people have attached all kinds of cameras and other FPV setups to the Phantom and it flies just fine, so why would the Getterback cause such instability?
