2 dogs. i dont think you flew a jab that revved at 5000 rpm. A rotax powered jab perhaps?
I agree though. We should have better engines avialable. I recall jabiru brought out a recommendation that the engines get a 25 hourly oil change. We immediately adopted this procedure IAW with factory directions. The 2200 engine was subject to this schedule at the time of the failure, and (at a guess) for the previous 100 hours leading up to it.
