Thanks Paul...I had a flameout on my Merlin (also in an UF), but everything pointed to an air bubble (“low speed” error msg, normal pump voltage). I like the idea of setting a pump voltage alarm which is why I asked how much above the norm would cause concern. I’ve got a JC Cheetah SE and a Kingtech K85G2 in the fleet...would like to set those planes up with alarms as well. Maybe I’ll start with 1.0v over max and keep an eye on the data logs.
