Thank you very much, JJB!
I found out that FRAP did not work cause i had CSV file that I somehow failed to convert with TXTlogToCSVtool.exe in the same directory as log files before finding and trying FRAP.
Flight over water is more obvious: it lost VPS readings as soon as it was about water and then it got somewhat random readings whenever it recovered.
Hi Pavel,
Flying low over water with some speed ; yes sometimes VPS height doesn`t measure the height, must be bad reflectings back to the sensor. I fly alot low over water, but always at low speed, had not yet any probem with height measuring. Enough about this to be read in the manual with cautions! and what not do do.
AFAIK VPS height (if withing range) is taken into account for height hold (like an assistence to the baro height signal), as seen in various logs when VPS measures intermittents things can go wrong regarding height holding.
Good question if barometric sensor is influenced by fast moves etc, many different opinions on this forum. I think yes a little and looks like that Flight Control calculations are not that fast in combination (and/or) with little underpowerd motors....MM loose some height in extreme flight moves (sport mode full fwd to aft for example).
But my good news! : when flying 'normal' MM does a great job flying perfectly!
PS some MM has other height hold problems, they loose power and droping uncontrolled in height. This is for DJI to solve!
cheers
