Hi, I just bought the APM 2.5 together with the Remzibi OSD (not the minimOSD). Now I try to get the connection from the APM to the OSD with the adapter calbe for telemetry http://store.diydrones.com/Adapter_cable_for_APM_2_5_p/kt-apm25-cable.htm EDIT:  I want to send a big thank you to Heino R. Pull who send me a lot of informations and the very good working code for the ardurino mini to start…
