I made this video to show Multiwii doubters or those thinking about giving up for a NAZA or KK board, that a Multiwii Pro with the proper settings can perform as well as those two platforms. All of the flying was done in extreme prop wash turbulence caused by the 4 huge 10 x 4.5 inch SF props without any GPS or altitude hold assist. I never had to make anything more than just very minor adjustments to the sticks to keep it in the air in front of the cam. a couple of times I took it above the camera but I was also doing a log test behind the scenes and needed the two altitude changes for the log.
