We operate an aircraft with GTISO 520 engines. Our SOPs are simple 55% power setting and slightly rich. Fuel is cheap but an overhaul is expensive.
I reckon that 'rutan around' and 'Lead Balloon' fly their own single engine aircraft which are both fitted with IO-520 engines. What about you, 'andrewr'?
