Got in some flights today before the rain gets here. Pretty nice at 75 deg, 6 knot wind.
Decided to try an 18x10 3BL PT model prop.
Same pipe setting, required a touch richer on low and high needle.
71-7200 top end, 5300 mid, 1900 idle, measured at end of 11 min flight.
Changed the sound to a deeper more pleasant note, which made me happy.
Performance was pretty nice for masters. Nice speed, downline speed just right. Doesn't pull the top radius as nice, may be a problem in heavier winds and heat. Will have to see. I'm thinking if this is a problem may be able to shorten pipe about an inch or so and gain some extra performance? Would have to see about that. Overall, I really liked the setup under todays conditions. Not as sharply responsive, which made things smoother. Pipe only gets slightly warm, which amazes me.
