I'll write about our trip to WV in a little while, but I wanted to ask about the performance I got from our Tiger this weekend. The plane was one of Tiger Aircraft's new planes.
The instructor when I checked out said to maintain about 2400 rpm for cruise, and Anthony Amorosi has mentioned the same rpm, I think. Now, in the Skyhawk SP with almost the same engine, 75% requires 2550 to 2600 rpm. On our trip this weekend, I held 2400 rpm, and looking at the book performance and the fuel I burned I don't think I was pulling even 65% power. We were at 6500 feet on the way there, and 7500 feet on the way back. We only got 118 knots TAS both ways. Now frankly, that's not the speed I've been led to expect out of the Tiger, and isn't any better than the Skyhawk SPs. I also only burned 22 gallons getting there, for a fuel burn of 7.3 gph. I leaned until rough, then enriched a bit, and kept the mixture rich enough to keep the CHT under 400. Obviously, I wasn't pulling much power. What rpm do other Tiger drivers use?
