Mike,
Yeah, I calibrated my torque meter a while back and discovered that I was using much higher torque settings in Cat I than I'd realized.
On the 23 minute flight, there was one bump about 3 minutes in, and a good bit more bumping starting around 12 minutes. Around 18 minutes, the model got out of reach of my steering pole, and while I Nick was bringing me his, the model hit the side of the "slot" and slid down from around 30' to the level of the rest of the ceiling, which is about 22'. I was able to catch it with the pole to keep really bad things from happening, but that much altitude loss really hurts the stopwatch. Unfortunately, that was the first and last time that session that I was able to get above 18' on the second climb because I couldn't get the model to start its second climb until after 10 minutes, which is waaay too late with the setup I'm using. Still worse, I found out later on that the hub bearing is getting sloppy, allowing the prop to drop to a lower than intended pitch around 19-20 minutes, which really damages efficiency.
