Default Another Update

"Just got back from an airshow here in QLD. Seem to be getting a handle on this aircraft at last. Cruising at 8500ft amsl, temp 42deg F, 4200rpm for a prop speed of 2320, 2 POB, luggage, full fuel etc, etc, we averaged 166knots. I am beginning to think I will stay with the IVO prop and just upgrade the blades and the turbo. Cooling is perfect…the logging for coolant temp varied 4-5 deg C for all conditions.

In constant climb to 8500amsl at 5 lbs boost,5000rpm, 90 knots, 2000fpm, 2 POB, 80 litres fuel and luggage, sees coolant temp at 84 deg C constant."

Let's face it... who wouldn't want two cool under-wing rads as neatly packaged as these ones? Can you say "shades of Spitfire"?

Pretty impressive performance numbers.
