Default RE: Possible Futaba 9CAP recall

As far as I know, the 9C "v-tail bug" is history. If you have the older stock with shorter Vr knobs, Futaba will exchange your processor FOC when you send it in for service. The newer stock with tall Vr knobs comes with the upgraded processor.

Technical description of the v-tail bug : In Glid2 mode, when programming the butterfly function with elevator compensation and vtail, the elevator servo travels twice the distance of the rudder servo (Both servos are suppose to travel equal distance). When elevator delay is used in butterfly, the rudder servo oscillates (It is suppose to move gradually to the endpoint).
