Hi Guernsey
You have got that one right, Grumpy comes from the grand-daughters who say that's what I am when not flying or freezing in a paddock trying to shoot something.
Doing the homework on the Jabiru 2200 supplied around 2013 as a aircraft I am looking at has one fitted, and most sites state they still have issues around the 300hr mark, any advice being from the home of these beasts
