I gotta agree Jim, #1 is just a stonger pack. And yes, I can tell a difference in flight. That last Immelman in Master's, it accelerates to the top. The other packs work fine, but I do find myself from time to time checking the throttle stick to see if it’s all the way up when carving the top corners.

I lost the Spin99 in July when I was shot down. Replacement is a Prestige, A60-20Sv2, CC-HV85. 10 lbs total weight with the 10SX…loving it! I never did have any issues with the Spin though. Another flyer at my club has a similar setup with the Spin and he doesn’t have any issues except that it lost his settings on him once.

Data logger was calibrated against the voltage reading from the 1010C back in the summer. I’m not sure why the logger isn’t correctly marking the flights (sessions), it used to do it just fine.

Six more flights today, here’s the last three (pack 1, 6 then 1 again.)
Let me see if I can attach a complete datafile…(change file extension back to FDR, using version 5.11)
