"When you move about the air rushing around the airframe causes turbulence, either increasing or decreasing the air pressure around the barometer, if it's losing altitude it is more than likely due to a lower pressure area around the baro,…"

"Must be mad busy indeed :). No need to help Dave. It flies excellent now - just saying my story. Anw I'll try again 11" props with lower stab_P due to your suggestion. Thanks. Brt "

Dave C replied to Dave C's discussion Arducopter Tuning Guide
"HI, sorry mad busy at the moment so no real time to help. But, that horrible flying is probably due to your stab_p being too high for your set up. Reduce stab_P to 3.5 or even 3 and try tuning again, you should be fine with your 11" props then."
