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.

Eastern Daylight Time, pequeajim@gmail.com writes: Is 2950 a typical cruise RPM? Is that running around 80%, and how does the 3300 like that RPM range? Jim, The short answer is yes, my engine seems perfectly happy at 2950. In fact, it seems happy running as high as 3150. That is the highest I have run it for extended periods. So for my airplane, engine and propeller combination all seems to be good at those rpms. My engine currently has about 365 hours total time in the past 21 months, and other than routine maintenance, it has been trouble free. The prop I am currently running is a Sensenich 64-ZK-55, and it is not the right prop as it still allows my engine to turn up quite a bit over 3300 rpm at full throttle. Nick is also experimenting with different props and we look forward to trying a 62-FJ-58 on the prototype and N31BZ as soon at they arrive. The prototype is currently running a 62-FJ-56, and this blade profile seems better for the entire rpm range. It will still turn over 3300 at full throttle, but the big difference we see with this blade profile is that the rpm is up on takeoff roll and climb out which results in shorter takeoff rolls and higher rates of climb. The extra pitch should allow a higher top end or the same speed at a lower rpm and thus less fuel flow. It remains to be seen if we will need to once again adjust the carb jets to optimize performance with the new prop. Along this line, Don in Australia has done some great experimenting putting a Revmaster throttle body injector on the 3300. In the long run, that may turn out to be the way to go, as it gives additional rpm and with a manual mixture control is more efficient at the higher altitudes.

It was in the same truck that delivered #49 to Bill in Arizona last Friday. Since Friday it has been to Los Angeles, shared the trailer with a car, visited Van's in Oregon and arrived here sharing the trailer with a RV-10. My delivery experience was the same as Bill's in Arizona right down to the rubbed area on the inside of the canopy. In my case the Partain driver, Seth, investigated the cause and determined that the scraped area was caused by a bundle of three aluminum tubes that was packed unprotected and unsecured inside the fuselage. He removed them from the fuselage so they couldn't cause any more damage. Note to factory: those tubes need to have bubble wrap around the ends of them when they are packed for shipping. I can't say enough about the TLC that Partain's driver Seth used in caring for my Lightning while it was under his care. Thanks in advance for the support that I have seen demonstrated to previous builders and that I hope to experience.
