Alan,
Great! Please keep me informed as to the numbers that the Eagle Tree comes up with.
Well I managed to leave the house today without the Eagletree Data Recorder
, but in any case everything was using the Nobler setup (timer, ESC, motor, prop, battery, lines). RPM on the APC TE 12-6 prop was, to refresh your memory, 7950 rpm. If anything, the PF was a hair faster than the Nobler--my Talking timer was giving me the 5 minute mark just midway in the clover, while the Nobler is just entering the clover at that point.
I drew 1600 mAHr out of the 4s2100mAHr pack, basically identical to recent Nobler flights. So within my understanding, the PF and Nobler are almost identical from today's flight. Fred timed me at 5.1s (nominal) a lap. I might prefer 5.0 s once I retrim the plane. Seems to be a slight warp--maybe a consequence of storing the PF up in my attic since last fall (2007). Not much. Also may need a bit more wingtip weight without the glow engine cylinder head hanging out further than the battery.
My setup looks similar to yours, I am using liberal amounts of velcro to hold the battery on with some rubber bands to give a little more secure feeling.
I just put on the Eagletree in case the weather tomorrow is better than forecast!
