The controller that you have will not eork with the Jeti Programming card. The stutter you are hearing is the controller telling you its time to land. A three cell Lipo pack can be taken down to 2.5v per cell (7.5v) so dont be alarmed if your three cell pack goes below 9v. The Jeti 08 3p auto detects the cell count of your pack by measuring the voltage of the pack. It is important that you only fly fully charged packs, if you connect a 3 cell lipo that is not fully charged (say 10v) The controller may detect it as an 8 cell nicd and then it might over discharge your Lipo, Hope this make sense!
