Issues with sky RC Toro 1s

[Martin.s]

I have been using this ESC for around a year with no issues at all. Recently installed new (Futaba) radio gear and now the Speedo will not work.

I've tried calibrating it to the new radio gear as per the Speedo instructions but all it will do is flash a slow green led with associated beep. Is it time for a new Speedo or can any help me get this running again?

Thank you!
