I quite agree. That is why I suggested setting trim to max cruise speed (which I guess correspond to +8/+9 lbs of boost). The very top speed any plane can reach is quickly bled off when one start to turn to aim anyway, I would think the +8/+9 lbs boost speed would make an appropriate compromise. 170 mph is a bit on the slow side though.
Helofly, what do you mean by cruise speed? Fuel economy fuels speed or max cruise speed? I think this difference is the crux of the matter. |
