I can see what they are this afternoon if you think it will help. I started with the basic settings they recommended and only had to change the ones having to do with altitude hold (pitch sensitivity and servo torque I think). However, based on the different wing, it will probably be different for your airplane. I recently was up with Linda in her Lightning doing the initial Trutrak set up so the settings she used would probably be similar for your airplane. By the way, congratulations on your first flight.

However, one odd occurrence was having a headwind when on an easterly heading - very unusual. My initial cruising altitude of 5,500 had about 7 to 10 on the nose which changed to 12 to 15 on the nose when I climbed to 7,500 over the mountains. Later that went to 15 to 20 as I got further into NC and VA. Dropping back down to 5.5 did not help and gave the same headwind component. Once again, my cross country technique is to set the fuel flow I am looking for and accept the rpm and airspeed this gives me. In this case, at 5,500 when I set 6.0 gph it gave me an rpm of 2950 to 3000 (the altitude hold causes the rpm to vary as it "flys" the airplane to keep the altitude constant) and the true airspeed was 155.9 mph. Actual fuel burn from start up to shut down (remember this would include start, taxi, run up, and climb to altitude) averaged out to 5.9 gph for the entire flight. Actual inflight fuel burn would probably be closer to 5.5 to 5.6. Now having made numerous cross country flights in the 10 to 14 thousand foot area and several in the 4 to 8 thousand area, I am about ready to say that you can expect to average about 160 mph (140 kts) true when in the lower area and 170 mph (150 kts) true when in the higher altitudes. Fuel burn seems to be about the same in either altitude band. If you want to impress your non pilot friends, tell them that you get about 28 mpg at 170 mph. Their Nash Rambler won't get anywhere that at half the speed.

Is that running around 80%, and how does the 3300 like that RPM range?
