Stupid question: I'm flying my RV-4 equipped with IO360 with CS prop. I'm headed for Hawaii and have past my no turn back point and realize I might not have enough fuel to make it. What speed and power setting would I use to stretch what I have left?
I read through some articles that seem to indicate best glide is probably the speed or close to it. I played with this a little on the transition to Oshkosh trying to fly 90 knot approach. 90 knot/105 mph requires a very small power setting like 15 in/1500 rpm. I tried leaning at this setting and couldn't ever get an EGT rise. I got down to around 3 GPH on the flow meter but got a little nervous being only 1,000 AGL.
Are there any gotchas running at these tiny power settings? Is there an optimum altitude? Will a little bit of flaps help?
