Performance Comparrison

combing through the thousands of data points from the G3X SD card I grabbed a comparison from todays flight vs. almost a year ago of similar DA and percent power. The data below is are averages from about 300 points each, two separate flights. The difference is last year it had a whirlwind GA and slick mags and now a Catto 3B 67x70, dual pmags and improved cowl saver baffles. Both slightly ROP. Both props top out +/- 161 KTAS @ 2700 RPM @ 8500 DA. It appears cruise is now faster & more efficient. Pmags are set to 0 adv shift and 30.8 max advance. I've enjoyed combing through the data and comparing performance settings
