Today I got some flights in between the rain storms. I flew using an 8.8 x 8.75 & the 9 x 7 APC "E". The flight with the 9 x 7 is after the second bar on the Data logger file. It is very close, but not there yet. It was about the same speed with both props. The 8.8 x 8.75 is my 428 prop of choice, but it works much better @ 20,000 than @ 13,000. The 9 x 7 "E" pulled much harder and accelerated much better. Hopefully the 9 x 7.5 & 9 x 9 APC "E" props will be here this week. The onboard data collector is a great tool. There is no substitute for live information.

Take care,
